Wisconsin's weirdest and most wonderful roadside attractions

World of Dr. Evermor, Intergalactic Time Traveler

Wisconsin is quietly one of America's greatest states for roadside oddities, and a family road trip here can include a 143-foot fiberglass fish you can stand inside, a Soviet satellite crash site, goats grazing on a restaurant roof, and a 320-ton steampunk machine built to launch its creator into the heavens.

From Milwaukee to the Northwoods, the Badger State delivers a density of quirky stops that rivals Route 66 — most of them free, nearly all of them family-friendly. What follows is a region-by-region guide to 31 attractions that range from beloved classics to genuine hidden gems, curated for Milwaukee-area families looking to turn any weekend drive into an adventure.

Milwaukee area: Bronze Fonz and more

The Bronze Fonz

The Bronze Fonz (Milwaukee) — A life-size bronze statue of Arthur "Fonzie" Fonzarelli from Happy Days stands in his signature double-thumbs-up pose on the Milwaukee Riverwalk at 117 E. Wells St. Local citizens raised $85,000 to erect the statue, sculpted by Gerald Sawyer. Actor Henry Winkler called it "truly beautiful" at the unveiling. It's Milwaukee's most-photographed statue and a perfect quick stop along the scenic Riverwalk. Free, all ages, accessible 24/7.

National Bobblehead Hall of Fame and Museum (Milwaukee) — The world's only museum dedicated entirely to bobbleheads houses over 10,000 specimens spanning sports, politics, pop culture, and the absurd at 170 S. 1st St. in Walker's Point. A built-in "Where's Waldo" scavenger hunt keeps kids engaged, and USA TODAY's 10Best named it a top-10 pop culture museum. Co-founders Phil Sklar and Brad Novak started collecting in 2002 and opened the museum in 2019. $5/person, children under 5 free. All ages.

SafeHouse (Milwaukee) — Operating since 1966 at 779 N. Front St., this spy-themed restaurant requires a secret password to enter. Those who don't know it must complete an on-camera "clearance test" — dancing, hula hooping, or making animal noises — broadcast to patrons inside. The interior features secret doors, rotating walls, hidden passageways, a piece of the Berlin Wall, and a different secret exit than the entrance. Families should visit during daytime hours; it becomes 21+ after 9 PM on weekends. No cover charge (pay for food/drinks). Family-friendly during lunch and early dinner.

American Science & Surplus (Milwaukee) — Part store, part curiosity cabinet, part treasure hunt at 6901 W. Oklahoma Ave. This employee-owned institution sells an ever-changing collection of surplus industrial, military, and scientific items — beakers, skeleton models, robot parts, rubber horse masks, whoopee cushions, and "items whose time has not come." Founded circa 1937 when Al Luebbers sold rejected camera lenses for 50 cents, it's a paradise for STEM-curious kids. The hilarious product descriptions alone are worth the trip. Free to browse (retail store). All ages.

Mars Cheese Castle (Kenosha) — This fairy-tale castle looming over I-94 at the Illinois-Wisconsin border houses 1,000+ varieties of Wisconsin cheese, sausages, a bakery, a full taproom, and a deli. Founded in 1947 by Mario and Martha Ventura (the "Mars" derives from Mario, inspired by the Roman god), the original store burned down in 1957 and was rebuilt. The current castle — complete with watchtower holding the wine collection — was redesigned in 2011. Free cheese samples make it the perfect road trip fuel stop. Free to enter. All ages.

Madison area: mustard, trolls, a pink elephant

National Mustard Museum (Middleton) — The world's largest collection of mustards — over 6,500 jars from all 50 states and 70+ countries — lives at 7477 Hubbard Ave., about 10 minutes west of Madison. Founded by Barry Levenson, a former Assistant Attorney General who started collecting mustard in 1986 after the Red Sox lost the World Series. Visitors can sample 100+ mustards at the tasting bar, browse "Poupon U" merchandise, and catch "MustardPiece Theatre" screenings. National Mustard Day (first Saturday of August) is a full festival. Free admission, donations encouraged. All ages.

Mount Horeb Trollway (Mount Horeb) — Over 40 hand-carved wooden troll statues line the streets of this village 20 miles southwest of Madison, each with its own personality: "The Chicken Thief," "The Accordion Player," and "Wavin' Walton" (born when lightning struck a 100-year-old white pine). Norwegian settlers brought troll folklore here, and when the highway was rerouted in the 1980s, the town doubled down on trolls to keep visitors flowing through downtown. Stop at the Welcome Center for a troll map, then grab lunch at the Grumpy Troll Brew Pub. The nearby Cave of the Mounds (4 miles west) makes for a perfect day trip pairing. Free outdoor art, accessible anytime. All ages.

Dr. Evermor's Forevertron (North Freedom/Sumpter) — A sprawling outdoor sculpture park off US Highway 12, about 14 minutes south of Baraboo, featuring hundreds of steampunk sculptures built entirely from scrap metal. The centerpiece is the Forevertron — a 320-ton, 50-foot-tall machine that Guinness recognized as the world's largest scrap metal sculpture. Created by retired industrial wrecker Tom Every (1938–2020), who worked without blueprints, the Forevertron incorporates Thomas Edison dynamos from the 1880s, the decontamination chamber from Apollo 11, and 1920s power plant components. The fictional backstory: Dr. Evermor built the machine to launch himself into the heavens on a "magnetic lightning force beam." Surrounding sculptures include 15-ton insects and a 70-piece bird orchestra made from instruments. Free, donations appreciated. Open Thu–Mon, closed Dec–Mar. All ages.

House on the Rock (Spring Green) — Perhaps Wisconsin's most legendarily bizarre attraction, this sprawling complex 40 miles west of Madison defies categorization. Highlights include the 218-foot Infinity Room cantilevered over a valley with no supports, the world's largest indoor carousel (269 animals, 20,000+ lights, hundreds of mannequin angels), rooms of self-playing music machines, and a giant sea creature. Built by Alex Jordan starting as a weekend retreat, it opened to the public in 1960 and features prominently in Neil Gaiman's American Gods. Often described as "the creepiest place in Wisconsin" for its surreal, overwhelming atmosphere. ~$30–35 adults, $16–18 ages 7–17. Best for ages 7+. Plan 2–4 hours.

Pinkie the Pink Elephant (DeForest) — A towering bubblegum-pink fiberglass elephant wearing oversized black glasses stands at a gas station just off I-90/94, about 15 minutes north of Madison. No explanation. No historical plaque. Just pure roadside whimsy. She's been here since the 1960s, originally placed to help the station stand out from competitors — created by Sculptured Advertising out of Sparta, Wisconsin. Free. All ages. Five-minute photo stop right off the interstate.

Wisconsin Dells: where kitsch is king

Top Secret: The Upside-Down White House

Top Secret: The Upside-Down White House (Wisconsin Dells) — A full-scale replica of the White House flipped completely upside down, resting on its roof at 2127 Wisconsin Dells Parkway. Walk through inverted rooms including the Oval Office, where all furniture and chandeliers hang above you. The fictional backstory claims the White House mysteriously crash-landed in the Dells, and an archaeological dig team is investigating. It's the largest upside-down White House in the country — twice the size of similar attractions in Florida and Tennessee. The exterior alone makes a great free photo. ~$5–7/person. Ages 6+. Takes 15–20 minutes.

Tommy Bartlett Exploratory (Wisconsin Dells) — A vintage-feeling, hands-on science center at 560 Wisconsin Dells Parkway that houses a real Russian MIR space station core you can walk through, alongside quirky optical illusions and interactive experiments. It evolved from Tommy Bartlett's Robot World of the 1980s–90s. The MIR module is an authentic piece of Russian space history — a surprising find in all-American Wisconsin Dells. ~$15–18 adults, discounted children's rates. All ages.

Door County: goats, ghosts, and bitters

Al Johnson's Swedish Restaurant & Butik (Sister Bay) — Live goats graze on the grass-covered sod roof of this Swedish restaurant at 10698 N. Bay Shore Dr. The tradition started as a prank in 1973 when Al Johnson's friend Winkie Larson bought him a goat named Oscar and tried to put it on the roof — breaking his collarbone in the process. The goats became world-famous. There's an online "Goat Cam," and the town holds an annual "Roofing of the Goats" parade each spring. The restaurant serves traditional Swedish pancakes with lingonberries. Free to watch goats from outside; moderately priced restaurant. All ages.

Nelsen's Hall Bitters Club (Washington Island) — Wisconsin's oldest continuously operating tavern, established in 1899. Visitors take a shot of Angostura bitters to become members of the legendary "Bitters Club" — a tradition dating to Prohibition, when owner Tom Nelsen obtained a pharmacist's license to legally serve bitters as "stomach medicine." Over a million members have been initiated. The island itself requires a ferry ride, adding to the adventure. Cost of a drink. Best for families with older kids who appreciate quirky history.

Green Bay and Fox Valley: hamburger birthplace and automatic fish

Home of the Hamburger (Seymour) — This small town 15 miles west of Green Bay claims to be the birthplace of the hamburger, marked by a 12-foot fiberglass statue of "Hamburger Charlie" Nagreen and a Hamburger Hall of Fame with 1,500+ pieces of burger memorabilia. The story: in 1885, 15-year-old Charles Nagreen was selling meatballs at the Seymour Fair. When nobody wanted to stop walking to eat, he flattened the meatballs between bread slices and called them "hamburgers." He sold burgers at the fair for 66 years. On display: the 22-by-22-foot "Charlie Grill" that cooked an 8,266-pound world-record hamburger in 2001. The annual Burger Fest (first Saturday of August) features a Giant Ketchup Slide. Free (Hamburger Hall of Fame inside Seymour Community Museum, open Sunday afternoons Memorial Day–Labor Day). All ages.

Tunnel of Automatic Fish (Green Bay) — A 110-foot-long pedestrian tunnel beneath the CityDeck area rigged with motion sensors connected to 22 translucent fish sculptures that pulse with LED lighting, simulating swimming motion as you walk through. Part of Green Bay's public art and waterfront revitalization along the Fox River. Free, accessible 24/7. All ages — kids love triggering the sensors.

Hearthstone Historic House Museum (Appleton) — The world's first home lit by a central hydroelectric station. On September 30, 1882 — just weeks after Thomas Edison's Pearl Street Station lit Manhattan — this Victorian mansion was illuminated using power from the nearby Fox River. Listed on the National Register of Historic Places, it showcases original Edison light fixtures. Appleton's claim to electric fame predates most cities in the world. ~$8–10 adults, reduced for children. Ages 8+.

Sheboygan and Lake Michigan corridor: space debris and submarine sleepovers

Sputnik IV Crash Site (Manitowoc) — A brass ring embedded in the middle of 8th Street marks the exact spot where a 20-pound chunk of the Soviet Union's Sputnik IV satellite crash-landed on September 5, 1962. Two police officers found the glowing hunk but initially thought it was scrap from a local foundry. The Smithsonian confirmed it was Soviet space junk; the Soviets reluctantly accepted the original back. A replica lives in the adjacent Rahr-West Art Museum. The annual "Sputnikfest" (September) features the Ms. Space Debris Pageant, Cosmic Cake competition, and Alien Drop raffle. Free to see the street marker and museum replica. All ages.

Wisconsin Maritime Museum & USS Cobia (Manitowoc) — Tour a fully restored WWII submarine docked in the Manitowoc River — or actually spend the night on it via "Sub Bnb" on Airbnb, choosing from 65 original sailor bunks. Manitowoc built 28 submarines during WWII. The USS Cobia sank enemy ships in the Pacific and is now a National Historic Landmark. The museum spans 60,000+ square feet, and the Waterways Room lets kids control water flow and locks. $12 adults, $10 children 6–15, under 5 free. Overnights ~$44/person. All ages.

Acuity Insurance Flagpole (Sheboygan) — The world's tallest flagpole at 400 feet flies the world's largest free-flying American flag — 70 by 140 feet, weighing 250 pounds. The flagpole itself weighs approximately 420,000 pounds, standing nearly 100 feet taller than the Statue of Liberty. Visible for miles around when the flag is at full staff, though it doesn't fly in rain or extreme wind. Free, with public parking, benches, and a reflective pond on the Acuity Insurance campus. All ages.

Bookworm Gardens (Sheboygan) — A whimsical, interactive botanical garden at 1415 Campus Drive entirely themed around children's literature. Garden areas bring classic books to life — climb aboard a Magic School Bus, explore scenes from Charlotte's Web and Curious George, and discover reading nooks throughout. 100% of TripAdvisor reviewers recommend it. Seasonal (May–October). Generally free or low-cost. Specifically designed for families with young children.

James Tellen Woodland Sculpture Garden (Town of Wilson, near Sheboygan) — A hidden woodland trail dotted with over 30 life-size concrete sculptures created by self-taught artist James Tellen (1880–1957). Figures depicting Abraham Lincoln, Native Americans, religious figures, and woodland creatures emerge unexpectedly from the forest. Tellen's masterpiece "Fallen Log" is a 65-foot-long trompe l'oeil log with bears and figures. He reportedly buried failed sculptures in his yard, enjoying the idea that future people would find "eerie cement heads." Preserved by the Kohler Foundation. Free, open daily 8 AM–6 PM. Best for ages 8+; younger children may find some sculptures unsettling.

Northern Wisconsin: giant creatures and mythical beasts

National Fresh Water Fishing Hall of Fame & Giant Musky (Hayward) — The undisputed king of Wisconsin roadside attractions: a 143-foot-long, 4.5-story-tall fiberglass muskellunge — the world's largest fish sculpture, as long as a Boeing 757. Visitors enter through the musky's tail and climb to an observation platform in its gaping jaw that holds 20 people and has been used for weddings. Below sits an 88,000-gallon stocked fishing pond. The 7-acre museum complex contains 50,000+ fishing artifacts. Built in 1976 by FAST Corporation of Sparta. ~$8.95 adults. Open mid-April through October. All ages.

The Hodag (Rhinelander) — A larger-than-life fiberglass sculpture of the Hodag — a fearsome mythical creature "discovered" in 1893 by prankster Eugene Shepard, described as having "the head of a frog, the face of a giant elephant, thick short legs with huge claws, and a long tail with spears at the end." Through the "Hodags on Parade" initiative, over 24 hand-painted Hodag statues are scattered throughout town. The hoax was so convincing the Smithsonian announced a visit before Shepard confessed; P.T. Barnum traveled to Rhinelander to try to buy the creature. Use the town's "Hodag Finder" map for a full monster hunt. Free, accessible 24/7. All ages — kids love the scavenger hunt aspect.

Claire d'Loon — World's Largest Talking Loon (Mercer) — A 16-foot-tall, 2,000-pound fiberglass loon with an interactive voice box in front of the Mercer Chamber of Commerce. Press buttons to trigger four different loon calls (hoot, tremolo, yodel, wail). Mercer is officially the "Loon Capital of the World" based on wildlife studies finding the highest concentration of nesting loon pairs in the continental US. Claire has been shot at least twice but was repaired and made to "talk" again in 2015. Free, visible 24/7. All ages — kids love pressing the buttons.

World's Largest Penny (Woodruff) — A 10-foot-wide, 17,000-pound concrete replica of a 1953-D Lincoln penny. It commemorates a remarkable story: local doctor Kate Newcomb ("the Angel on Snowshoes") and a teacher led a campaign to collect one million pennies to build a hospital in the remote Northwoods. The story went national, pennies arrived by the pound from across the country, and the effort raised about $106,000 (over $1.2 million in today's dollars). Woodruff got its hospital in 1954. Free, always visible. All ages — great story about community generosity.

Fred Smith's Wisconsin Concrete Park (Phillips) — A National Register of Historic Places folk art masterpiece featuring 237 life-size and larger concrete sculptures among shady trees on Highway 13. Created by retired lumberjack Fred Smith (1886–1976) with no art training, the figures depict Paul Bunyan, Abraham Lincoln, cowboys, and animals — all made from concrete embellished with beer bottle glass, mirror shards, and car tail lights. When asked why, Smith said: "Them ideas is hard to explain, ya know... Nobody knows why I made 'em, not even me." His final piece was a full Budweiser beer wagon with Clydesdale team, completed just before a stroke ended his work in 1964. Free, donations appreciated. Gift shop open seasonally. All ages — bring bug spray.

Central Wisconsin: scrap-metal dinosaurs and a talking cow

Jurustic Park (Marshfield) — A gloriously weird outdoor sculpture garden at 112021 Old Sugarbush Lane featuring hundreds of fantastical creatures made from rusted scrap metal, created by retired attorney Clyde Wynia. Dragons with working propellers, monsters with dagger-teeth, frog-gunslinger hybrids — many rigged with handles to make them wiggle and clang. Clyde plays a deadpan amateur paleontologist claiming these are "extinct Iron Age creatures dug up from the nearby marsh." He has nearly 1,000 sculptures, each with a name: "Oxide the Watchdog," "Porky-Pine the Half-Pig-Half-Porcupine," "Abe Lawbender the lawyer from Shysterville." RoadsideAmerica.com rates it "Major Fun." His wife Nancy creates hand-blown glass art in the on-site "Hobbit House." Free, donations accepted. Open May–Aug, Mon–Sat 10 AM–4:30 PM, Sun 12–4:30 PM. All ages.

Chatty Belle — World's Largest Talking Cow (Neillsville) — A 16-foot-tall, 20-foot-long fiberglass Holstein — seven times actual cow size — with a coin-operated voice box that delivers a friendly monologue. She was originally Wisconsin's contribution to the 1964 World's Fair in New York before being brought home to Neillsville. Built by FAST Corporation in Sparta. She has her own Facebook and Twitter accounts. Free (coins for the voice box). Always visible roadside. All ages — little kids absolutely love her.

Chainsaw Forest (Medford) — At the corner of County Highway M and Division Drive stands a small forest of 21 poles with roughly 400 chainsaws sticking out of them — a surreal, slightly menacing tribute to Wisconsin's lumber heritage. Nobody seems entirely sure of its full origin story, which only adds to the mystique. Free, roadside, always visible. All ages.

Western Wisconsin: giant beer and a bicycling capital

World's Largest Six-Pack (La Crosse) — Six 54-foot-tall steel storage tanks painted to look like a giant six-pack of beer stand at 1111 S. 3rd St., next to City Brewing Company. Originally painted in 1970 as Heileman's Old Style Lager, the tanks actually contain real beer — collectively holding 688,200 gallons, enough to fill 7,340,796 twelve-ounce cans, which would provide one person a six-pack a day for 3,351 years. Across the street stands a statue of King Gambrinus, the legendary patron saint of beer, hoisting a golden goblet. Free to view from the road. All ages enjoy the sheer scale.

Ben Bikin' — World's Largest Bicyclist (Sparta) — A 32-foot-tall statue of a Victorian-era gentleman riding a penny-farthing bicycle at the entrance to town. Sparta bills itself as the "Bicycling Capital of America," home to the Elroy-Sparta State Trail — the first rails-to-trails conversion in the United States. Even better: the FAST Corporation, maker of many of America's giant fiberglass roadside statues (Hayward's musky, Mercer's loon, Neillsville's cow), is headquartered here. Visitors can see their "mold graveyard" of discarded statues — a hidden gem within a hidden gem. Free, always visible. All ages.

Planning your quirky Wisconsin road trip

Most of these 31 attractions cluster into natural day-trip or weekend routes from Milwaukee. A southern loop hits Mars Cheese Castle, the Bronze Fonz, and the Bobblehead Museum in a morning, then pushes west to Mount Horeb's trolls and the Mustard Museum by afternoon. The "Weird Central" corridor along Highway 12 connects Dr. Evermor's Forevertron, House on the Rock, and the Dells in a single spectacular day. A Northwoods expedition threads together the Giant Musky, Hodag hunt, Claire d'Loon, and Concrete Park over a weekend, with Jurustic Park and Chatty Belle on the drive home.

A few practical tips for families:

• Best bang for your buck: Over two-thirds of these attractions are completely free. Many paid attractions (Mustard Museum, Concrete Park, Forevertron) accept donations in lieu of admission.

• The FAST Corporation connection: Sparta-based FAST Corporation manufactured many of Wisconsin's fiberglass giants — the Hayward musky, Mercer's loon, Chatty Belle, Pinkie the elephant, and Ben Bikin'. Visiting their "mold graveyard" in Sparta ties the whole quirky ecosystem together.

• Seasonal awareness: Northern attractions and outdoor sculpture parks generally operate May through October. House on the Rock runs mid-March through early November. The Dells attractions have the longest seasons.

• Hidden gem pick: Jurustic Park in Marshfield deserves far more attention than it gets. Clyde Wynia's deadpan comedy, the interactive sculptures, and Nancy's Hobbit House glass studio make it one of the most genuinely delightful stops in the state.

Conclusion

Wisconsin's roadside landscape reveals something deeper than kitsch — it's a state where retired lumberjacks build concrete armies, former attorneys weld scrap-metal dragons, and industrial wreckers construct machines to reach the heavens. The common thread isn't weirdness for weirdness' sake. It's a tradition of stubborn, joyful creativity rooted in long winters and independent spirits. For Milwaukee families, that means the entire state is essentially a free, open-air museum of American folk imagination, and nearly every highway exit has a story worth pulling over for.
