Elroy-Sparta State Trail: The ultimate family guide
America's first rail-trail is a near-perfect family adventure — 32.5 miles of gentle, crushed-limestone path through Wisconsin's scenic Driftless Area, punctuated by three pitch-dark, hand-dug 1870s railroad tunnels that will have your kids talking for years. At roughly two and a half hours from the Milwaukee area, the Elroy-Sparta State Trail offers an accessible weekend escape packed with small-town charm, tunnel thrills, and ice cream stops. Here's everything you need to plan the trip.
The trail runs between the towns of Elroy (eastern end) and Sparta (western end), passing through Kendall, Wilton, and Norwalk along the way. Built on an abandoned Chicago and North Western Railway line, the corridor was purchased by the state for just $12,000 in 1964 and opened to the public in 1967 — earning its place in history as America's very first rail-trail conversion. It was named a National Recreation Trail in 1971 and inducted into the Rails-to-Trails Conservancy Hall of Fame in 2008. Today, more than 60,000 riders use it annually.
Tunnels carved by hand and dynamite
The tunnels are the undeniable headliner. All three were blasted through solid rock in 1873 to carry trains through the ridges of the Driftless Area. Each features massive 20-foot-tall wooden double doors at both ends — originally opened and closed by watchmen for passing trains — and year-round interior temperatures hovering around 50°F, even on the hottest summer days. They are completely unlit inside, water drips steadily from the ceilings, and you must walk your bikes through all of them.
Tunnel #1 sits between Kendall and Wilton, about 3.3 miles west of Kendall. At roughly 1,694 feet (about a third of a mile), it's the driest of the three and the best introduction for young kids. The surrounding approach features a natural canopy of trees that feels like entering a storybook. Tunnel #2, between Wilton and Norwalk, is also approximately 1,694 feet long. Its interior was refurbished with a brick and masonry liner in 1878, and both portals feature handsome arched entrances. Small safety niches from the railroad era are carved into the walls.
Tunnel #3 is the showstopper — and the most intimidating. At 3,810 feet (nearly three-quarters of a mile), it is the longest railroad tunnel in Wisconsin, stretching longer than ten football fields. Water drips so heavily that visitors describe it as "raining" inside. On humid days, fog can fill the interior, making it impossible to see the light at the far end. Budget 15 to 20 minutes to walk through. A reconstructed watchman's shack and an eight-foot-deep stone drainage flume sit at the eastern entrance. This tunnel is home to the northern long-eared bat, a federally threatened species — one reason all three tunnels close from November 1 through April 30.
Flashlights or headlamps are essential. The Wisconsin DNR officially says "recommended," but in practice you cannot safely navigate these tunnels without a light source. Headlamps are ideal for kids since they keep hands free. Pack a light jacket or sweatshirt — the 50°F temperature feels shockingly cold after biking in summer heat — and consider a lightweight rain poncho for Tunnel #3's relentless dripping.
Distances, surface, and which direction to ride
The trail surface is crushed limestone, firm and smooth enough for hybrid and mountain bikes but not ideal for road bikes. The grade never exceeds 3%, but the sustained climbs approaching each tunnel can tire younger riders. The trail's total elevation change is about 194 feet.
Here are the town-to-town distances:
Segment Distance Elroy → Kendall 6.3 miles Kendall → Wilton 9.1 miles (includes Tunnel #1) Wilton → Norwalk 5.8 miles (includes Tunnel #2) Norwalk → Sparta 12.3 miles (includes Tunnel #3) Total ~32.5 miles
One important tip: riding from Elroy to Sparta is the net-downhill direction, making it the easier ride and the preferred route for families using shuttle services. Many families arrange a one-way shuttle drop-off and ride back to their car.
How to match trail sections to your kids' ages
Not every family needs to tackle all 32.5 miles. The trail's town-to-town structure makes it easy to pick the right segment for your crew.
Families with kids ages 4 to 6 should plan for bike trailers or trail-a-bikes (available for rent at Speed's Bicycle Shop in Sparta). The crushed limestone surface handles trailers well. The best option is parking at the Kendall Depot and riding the 3.3 miles west to Tunnel #1 and back — a 6.6-mile round trip that delivers a full tunnel experience without overdoing it. Alternatively, the flat Elroy-to-Kendall stretch (6.3 miles one-way) is the easiest segment with no tunnels. Keep total mileage under 10 miles for this age group. Standard strollers struggle on crushed limestone; a jogging stroller with large wheels can manage.
Families with kids ages 7 to 10 can handle longer distances. The Kendall-to-Wilton segment (9.1 miles, including Tunnel #1) is an excellent one-way ride with a shuttle back. For a round trip, the Kendall-to-Tunnel #1 out-and-back remains a great choice. Target 8 to 14 miles for the day. Tunnel #1 is the friendliest for this age group — Tunnel #3's length and darkness can genuinely frighten younger kids.
Families with strong riders ages 11 and up can tackle multi-tunnel days. Kendall to Norwalk (about 15 miles) covers Tunnels #1 and #2 with a lunch stop in Wilton. Ambitious families can ride the full trail from Kendall to Sparta (roughly 27 miles) and hit all three tunnels, budgeting 4 to 6 hours with stops.
Trail passes, bike rentals, and shuttle logistics
A Wisconsin State Trail Pass is required for all cyclists age 16 and older. Daily passes cost $5 per person; annual passes are $25. Children under 16 ride free, and hikers and walkers need no pass at all. You can purchase passes online through the Wisconsin DNR website, at the Sparta Chamber of Commerce depot (111 Milwaukee Street), Speed's Bicycle Shop (1126 John Street, Sparta), the Kendall Depot (113 White Street), or Elroy Commons. Self-pay kiosks are located at trailheads in Wilton and Norwalk.
Speed's Bicycle Shop in Sparta has been the trail's primary bike rental and shuttle operation for years, renting mountain bikes, comfort bikes, tandems, child trailers, trail-a-bikes, and electric-assist bikes. Military and group discounts are available, and they've historically offered van-and-trailer shuttle service to any trailhead along the route. However, their website recently noted the business is for sale — call ahead at 608-269-2315 to confirm 2026 operations before building your trip around them. Additional bike rentals are available at the Kendall Depot (608-463-7109), Elroy Commons at the eastern trailhead, and the Tunnel Trail Campground between Kendall and Wilton (campers only, $25/day).
For shuttle alternatives, Caboose Cabins in Sparta (608-269-0444) offers private shuttle service. The Sparta Chamber of Commerce runs a "Trail Ambassadors" volunteer program where someone rides with you to one end and drives your car to the other for about $25. The Kendall Depot also provides shuttle service for approximately $22. Always call ahead and make reservations.
The trail and tunnels are open May 1 through October 31. Peak season runs June through August, but early June and September offer pleasant temperatures with thinner crowds. The trail itself remains open year-round for hiking and snowmobiling, but the tunnel closures make the biking season effectively May through October.
Five trail towns worth exploring
Each trail town has its own personality and offerings. Here's what families should know:
Elroy (eastern terminus) is the trail's hub, where three trails converge — the Elroy-Sparta, the 400 State Trail, and the 13-mile Omaha Trail. The Elroy Commons trailhead features bike rentals, showers, concessions, a playground, and picnic areas. Don't miss the Elroy Historical Society Museum with its railroad exhibits and 1930s model train display, or Wisconsin's only open-lattice pedestrian covered bridge — a great family photo spot. Dining options in Elroy are limited, so stock up on snacks at the Commons before heading out.
Kendall serves as the official trail headquarters, housed in a beautifully restored railroad depot that doubles as a small museum. The Hidden Inn Bar & Grill is the town's go-to family meal stop, known for charbroiled burgers and steaks with outdoor picnic seating. This is a smart place to park for families planning a Tunnel #1 out-and-back ride.
Wilton sits right between Tunnels #1 and #2, making it a natural mid-trail rest stop. The Dorset Valley Schoolhouse Restaurant is a real gem — housed in a historic 1848 one-room schoolhouse, it serves old-fashioned country cooking and is locally famous for its Friday fish fry. The Hitchin' Post dishes up cheese curds, pizza, and burgers, and trail riders report they'll fill your water bottles with ice water. A gas station and convenience store sit right beside the trail for emergency snack runs.
Norwalk — self-proclaimed "Black Squirrel Capital" — is a charming stop with two standout food options. Bailey's Diner (104 Railroad Street) is an authentic Mexican restaurant with a 4.8-star rating that trail riders consistently rave about — try the tacos, tamales, and horchata. Lesa T's Creekside Cafe serves hot dogs, grilled cheese, and critically important soft-serve ice cream with outdoor picnic seating right off the trail. The Norwalk Village Park has playgrounds, shelters, public bathrooms, and showers available for trail users.
Sparta (western terminus, population ~10,000) is the largest town and self-proclaimed "Bicycling Capital of America" since 1990. The must-see landmark is "Ben Bikin'" — a 32-foot-tall fiberglass statue of a Victorian-era cyclist on a penny-farthing bicycle, located at the corner of Highway 16/71 and Water Street. Built by local company F.A.S.T. Corp. (which manufactures giant fiberglass roadside statues), it holds the world record for largest bicyclist statue and features an audio box narrating Sparta's history. The Deke Slayton Memorial Space & Bicycle Museum (166 South Water Street) is a surprisingly fascinating stop, honoring Sparta-native Mercury Seven astronaut Deke Slayton alongside a collection of 200-plus historic bicycles. Kids who love quirky roadside attractions will enjoy the F.A.S.T. Corp. fiberglass mold graveyard, an outdoor display of colorful molds from the statue factory.
For dining in Sparta, Rudy's Drive-In is a classic — house-made root beer, burgers, cheese curds, and ice cream at an old-fashioned drive-in. Ginny's Cupboard (127 North Water Street) serves coffee, desserts, and ice cream downtown. Sparta Family Restaurant is the reliable all-day breakfast and homestyle spot where locals eat. For a proper Wisconsin supper club experience, Club Oasis delivers prime rib and Friday fish fry. Pizza lovers should try Slice of Chicago for deep-dish.
Where to sleep along the trail
The standout family camping option is Tunnel Trail Campground (26983 State Highway 71, Wilton), located directly on the trail between Kendall and Wilton. This family-owned campground has operated for over 52 years and offers tent sites, RV hookups, and cabins, plus a heated swimming pool, mini golf, hot showers, laundry, a game room, a playground, and a camp store. It rents bikes to registered guests. Open May through mid-October, it is the most amenity-rich base camp on the trail.
The Norwalk Lions Park Campground is another strong choice — centrally located right on the trail next to Bailey's Diner, with electric sites, tent camping, shelters, bathrooms, and showers. Primitive DNR campgrounds with walk-in tent sites, fire rings, hand-pump water, and vault toilets are located at both trail endpoints in Elroy and about a mile east of Sparta.
For indoor comfort, Sparta has several family-friendly hotels. The Best Western Plus Sparta Trail Lodge (from roughly $107/night) offers an indoor pool, hot tub, complimentary breakfast, and an on-site pub. The Country Inn & Suites by Radisson (from roughly $97/night) also has an indoor pool and free breakfast right off I-90. Budget options include the Super 8 (from about $59/night, pet-friendly) and Best Nights Inn.
For something special, Justin Trails Resort sits on 200 acres eight miles south of Sparta in a private coulee. The property offers luxury farmhouse B&B suites, handcrafted Scandinavian log cabins, a garden cottage, and glamping — plus 14 miles of private trails, two disc golf courses, pet llamas, nightly bonfires, and stargazing. Hearty breakfasts are included for B&B and cabin guests. In Wilton, Amil's Inn B&B features Amish-crafted beds and whirlpool rooms, and the Mid-Trail Motel has connecting rooms ideal for families. Near Elroy, Waarvik's Century Farm B&B is a 150-year-old hand-hewn log cabin on a working farm.
Getting there
The drive from the Milwaukee area to Elroy (the eastern trailhead) is approximately 154 miles, or about 2 hours and 30 minutes via I-94 West and Highway 82. Sparta (the western trailhead) is roughly 184 miles and about 2 hours and 45 minutes via I-94 to I-90 West. Both routes pass through the Madison and Wisconsin Dells corridor.
The Elroy-Sparta Trail is part of a remarkable interconnected network totaling more than 100 miles of trails. At the Elroy end, it connects directly to the 400 State Trail (22 miles southeast to Reedsburg through the Baraboo River valley) and the Omaha County Trail (13 miles northeast to Camp Douglas near Mill Bluff State Park, featuring its own shorter rock tunnel). At the Sparta end, a bridge over Interstate 90 links it to the La Crosse River State Trail (22 miles northwest to the La Crosse area), which in turn connects to the Great River State Trail running 24 miles along the Mississippi River. In theory, you could ride continuously from Reedsburg to the Mississippi.
What to pack for a family tunnel adventure
Gear makes or breaks this trip, especially for the tunnels. Here is what experienced trail families recommend:
Headlamps for every family member — far superior to handheld flashlights because kids need both hands for steering and walking bikes. Bring backup batteries or a spare light.
Light jackets or sweatshirts that can be tied around waists between tunnels — the 50°F temperature drop is abrupt and dramatic.
Lightweight rain ponchos for Tunnel #3's heavy water dripping. Some families cover bike seats with plastic bags before entering.
Old shoes or waterproof shoes for walking through puddles, especially in Tunnel #3.
Plenty of water and trail snacks — there are no services between towns. Granola bars, trail mix, fruit, cheese sticks, and PB&J sandwiches travel well in handlebar bags.
Sunscreen and bug spray for the exposed stretches between towns.
A small first-aid kit with bandages and antiseptic for inevitable minor scrapes.
Toilet paper and hand sanitizer — vault toilets at trailheads don't always have supplies.
Conclusion
The Elroy-Sparta State Trail delivers a rare combination for family travel: genuine historical significance, physical adventure scaled to nearly any age, and the unpretentious warmth of small Wisconsin trail towns. The tunnel experience — walking into absolute darkness at 50 degrees while water drips onto your helmet — is the kind of sensory memory that defines a childhood summer. For Milwaukee-area families, the roughly 2.5-hour drive puts it squarely in weekend-trip range, and the trail's flexibility means you can tailor the outing to a half-day pedal with preschoolers or a full-day, three-tunnel epic with tweens. Start at Kendall for the easiest tunnel access, book a spot at Tunnel Trail Campground if you want to make it an overnight, and don't skip Bailey's Diner tacos in Norwalk or Rudy's root beer in Sparta. This is Wisconsin family biking at its best.
