Wazee Lake Recreation Area: Wisconsin’s deepest lake

Wazee Lake Recreation Area is a 1,300-acre county park built around a flooded iron mine 3 hours northwest of Milwaukee — and it's one of the most unusual outdoor destinations in the state. At 355 feet deep with turquoise, spring-fed water, Wazee holds the title of Wisconsin's deepest inland lake and doubles as the Midwest's most popular scuba destination.

It also features a clean sandy beach with shallow shoreline water for little kids, roughly 12 miles of easy hiking and biking trails, rustic lakeside camping at $12 a night, and a surrounding region — the Black River State Forest and Jackson County Forest — that adds more than 200,000 acres of public land within a 30-minute radius. This guide treats Wazee as a weekend base camp and walks through what to do, when, and what to bring in every season.

A quick orientation note: Wazee sits just east of Black River Falls at N6302 Brockway Road, reached via I-94 Exit 116. Plan about 3 hours from Milwaukee (≈195 miles) via I-94 West, with natural stopping points in Madison, Wisconsin Dells, or Tomah. The lake was born in 1983 when Jackson County Iron Company shut off the pumps at its taconite mine; groundwater filled the 355-foot pit over the next decade. "Wazee" means tall pine in Ho-Chunk.

What to expect at Wazee

The park's personality splits cleanly in two. The east end holds the family side: a large semicircular sand beach carved into the shoreline, a newer concession/flush-restroom building (added in 2020), a playground, a pavilion, a handicap-accessible fishing pier, and a boat launch. The water near shore stays under four feet deep for a good stretch — comfortable for kids who aren't strong swimmers — but there are no lifeguards, so parent supervision matters more than usual given the lake's extreme depth just offshore. The rest of the park is wild: red iron cliffs along the northwest shore, restored pine-oak barrens, a semi-surprising 18-hole disc golf course, and trails winding through former mine terrain.

The trail system totals roughly 9 miles of hiking trail plus a 3-mile surfaced (crushed-stone) bike trail, which together form an approximately 6-mile loop around the lake. Difficulty is easy to moderate with rolling terrain and a few climbs to rim overlooks. Trails are shared between hikers and mountain bikers, and e-bikes are permitted. The surfaced lakeside route works well for families with jogging strollers or new riders; the dirt spurs into the surrounding woods give more adventurous hikers and bikers room to roam. Trail maps are posted at the Black River Area Chamber site and via the Avenza Maps app.

Scuba is the park's claim to fame. More than 1,000 divers visit each year to explore submerged mine roadways, a 40-foot vertical wall simply called "The Wall," a drowned tree stand known as "Sherwood Forest," training platforms at 35, 70, and 90–110 feet, a sunken boat, and a novelty skeleton at depth. Summer visibility runs 30 to 40 feet; winter clarity can reach 60 to 100 feet because algae dies back. Three distinct thermoclines drop water temperature from a summer surface of 70°F to 34°F below 70 feet, so dry suits are strongly recommended for deep dives. A dive flag is mandatory and locally enforced. Wazee Sports Center on Highway 54 is the on-site go-to for air fills, gear rental (including kayaks and SUPs), and instruction.

Fishing is a two-tier affair: stocked brown, rainbow, and brook trout share the water with smallmouth and largemouth bass, bluegill, walleye, and panfish. Trout tend to hold deep — experienced anglers report 15- to 20-inch fish at 60 to 90 feet on white jigs tipped with minnows. No gasoline motors are allowed on the lake (electric trolling motors, kayaks, canoes, paddleboards, and rowboats are fine), which keeps water clarity and noise down.

Fees, hours, and practical amenities

Daily vehicle admission is $3 to $5 and an annual pass runs $25 to $30 — Jackson County's newer fee sheet lists $3/$25, while on-site reports from 2023 and 2024 cite $5 at the gate, so budget for $5 and you'll be covered. Scuba divers pay an additional $10 per day or $75 per year. Camping is $12 per night at 12 rustic lakeside sites (6 reservable with a 3-night minimum, 21-night max; plus a $7 reservation fee). The park is open 6 a.m. to 11 p.m. daily year-round; the beach and staffed contact station run Memorial Day through Labor Day, with self-registration the rest of the year. Campground season runs April through December. Call (715) 284-3171 in summer or (715) 284-8475 off-season to confirm current fees before you drive up.

Amenities include flush toilets at the new beach building, vault toilets elsewhere, drinking water, a seasonal concession stand (limited — pack food anyway), an ADA-accessible fishing pier, paved handicap parking at dive sites, and a leash-law for dogs with a hard rule: no dogs at the beach or picnic areas. Showers are not on site — the closest are at Castle Mound Campground or the Flying J travel plaza in town. Cell service is spotty; download offline maps before you arrive.

Where to go within 30 minutes of Wazee

The surrounding public land is Wazee's secret weapon. The Black River State Forest (68,000 acres) and Jackson County Forest (120,000+ acres) wrap around the park, and together they offer a lifetime of return trips.

Castle Mound Nature Trail, fifteen to twenty minutes away off Highway 12, is the single best half-day add-on. A 1.5- to 2-mile loop with about 300 feet of climbing delivers you to a Cambrian sandstone butte that rises 180 feet above the sand plain — a state-designated Natural Area since 1952 — where a short spur and a steel ladder reach an old fire-tower observation deck with panoramic views of the former Glacial Lake Wisconsin basin. AllTrails users rate it 4.6 stars. Castle Mound Campground at the trailhead is the region's most developed, with 35 sites (14 electric), hot showers, flush toilets, an ADA electric site, a playground, a dump station, and year-round access.

The Smrekar and Wildcat trail systems near Millston (20 to 25 minutes from Wazee) add 22 to 24 miles of multi-use trail across seven to nine loops for hiking, mountain biking, and Nordic skiing. The Ridge, Norway Pine, and Wildcat loops are steep and expert-only; the South Trail is a beginner's 1.5-mile roll. Smrekar's trailhead has a heated warming shelter, drinking water, and pit toilets — critical in winter. Two Adirondack shelters with fireplaces are scattered through the system.

Dike 17 Wildlife Area (20 to 25 minutes east) is the region's best birding destination bar none. Thirteen flowages across 3,100 to 5,000 acres host breeding bobolinks, sedge wrens, golden-winged warblers, whip-poor-wills, four owl species including short-eared owls hunting at dusk, and the original release pen for central Wisconsin's reintroduced elk herd. An observation tower along Rustic Road 54 gives marsh views. There are no bathrooms and no marked trails — come prepared.

Lake Arbutus at Hatfield (20 to 25 minutes northwest) is the motorized counterpoint to Wazee: 821 acres of impoundment on the Black River where waterskiing, pontooning, jet-skiing, and walleye/musky fishing are welcome. Whitewater releases below Hatfield Dam on scheduled 2026 dates (June 13, July 11, August 8, September 12) draw Class II–IV paddlers; a standing surf wave appears at high flows.

In town, Lunda Community Park has a splash pad, playground, bandshell (free Tuesday-night summer concerts), and connects to Black River Falls' 4.1-mile paved Foundation Trail loop. The Lunda Community Center houses an indoor waterpark, climbing wall, and field house — a rainy-day lifesaver. Hoffman Aquatic Center runs an outdoor pool for about $5 in summer. Ho-Chunk Gaming offers a renovated hotel ten minutes from Wazee for non-campers. Bruce Mound Winter Sports Area in Merrillan (25 to 30 minutes north) is the regional downhill ski and tubing hill (note: the "Skyline" in Black River Falls is a golf course, not a ski area — its only winter use is ungroomed cross-country skiing). The Wisconsin Cranberry Discovery Center in Warrens (25 to 30 minutes south) anchors an entire afternoon of bog tours and cranberry ice cream.

Spring: wildflowers, warblers, and mud season

Ice typically leaves Wazee in early to mid-April, a week or two later than shallower central-Wisconsin lakes because of its depth. The reward for showing up in late April is bloodroot, spring beauty, hepatica, and Dutchman's breeches blooming in the hardwood understory, followed by large-flowered trillium peaking in mid-May and wild lupine (the only food plant of the endangered Karner blue butterfly) coloring the oak-savanna barrens from mid-May through June. The Bauer-Brockway Barrens and open corridors along Rustic Road 54 are prime lupine territory.

The Karner blue itself flies in two broods: late May to mid-June, then mid-July to early August. Spring warbler migration peaks in early to mid-May in the Castle Mound and Perry Creek hardwoods. Sandhill cranes, trumpeter swans, and teal populate the Dike 17 flowages. Wisconsin's 2026 general fishing opener is Saturday, May 2, and — in a notable rule change — inland trout harvest opens a month earlier than it used to, running April 4 through October 15, 2026.

A practical warning: March and early April are mud season, and many multi-use trails are soft, rutted, or informally closed. Ticks are active anytime temperatures rise above 40°F, and Pigeon Creek has a documented tick problem. Bring layers for 30s-to-60s temperature swings, waterproof boots, rain gear, permethrin-treated pants, and binoculars.

Summer: beach days, bug spray, and bass

Summer is when the Wazee beach earns its keep. Surface water warms into the low 70s by July, the concession building opens, and the shallow swim area handles toddlers well. The parallel story is underwater: scuba training classes fill the dive sites most weekends, and divers have right-of-way at the fish cribs near the boat launches (occasionally a frustration for anglers). Mountain bikers get their best conditions of the year on the 34 miles of designated singletrack across the Black River State Forest.

Camping demand peaks June through August, so reserve Castle Mound and Pigeon Creek sites up to 11 months in advance through the Wisconsin State Park system or 888-947-2757. Wazee's own 12 rustic sites can be booked via Jackson County's reservation portal. Bring potable water to Pigeon Creek — the hand pump has run brown in recent seasons.

Key summer events anchor weekend trips: the Black River Heritage Festival (formerly the Karner Blue Butterfly Festival) runs the third Saturday of July with parade, lumberjack show, 5K/10K, and trolley tours to the barrens and Wazee Lake. The Jackson County Fair runs July 28 through August 2, 2026 with a $10 admission for ages 9 and up.

Bugs are the summer tax. Mosquitoes peak at dawn and dusk from late May through August, and deer flies arrive with the hot afternoons of late June. Afternoon thunderstorms are common in June and July, and Wazee's open beach and ridgeline trails offer limited cover — check radar before you head out. Pack sun protection, water shoes, hydration for the drive, and a cooler with real food.

Fall: Wisconsin's best foliage weekend

Central Wisconsin's color peak lands in the first two weeks of October, with October 7 to 10 the statistical sweet spot per the state climatology office. Aspens and birches go gold first, followed by sugar maples (red and orange), then the oaks hold a russet curtain into late October. The best vantages within 30 minutes are Castle Mound's observation deck, the old mine-rim overlooks on Wazee's north loop, the Dike 17 observation tower, and a slow drive along Rustic Road 54 past Pigeon Creek.

Fall is also the region's least-crowded sweet spot — cool nights in the 30s and 40s, almost no bugs, and most campsites available after Labor Day. But a major caveat applies: this is hunting country. Wisconsin's archery season opens in mid-September, the nine-day gun deer season runs approximately November 21 to 29, 2026 (Saturday before Thanksgiving through the following Sunday), and muzzleloader and antlerless hunts extend through late December. The DNR strongly recommends that hikers, bikers, and dogs on public forest land wear blaze orange or fluorescent pink during any firearm deer season — at least 50% of clothing above the waist for hunters, and highly advisable for everyone else. Wazee itself is a county park where hunting isn't allowed, but the surrounding state and county forests are heavily hunted.

Fall is also cranberry-harvest season. The flooded bogs around Warrens turn brilliant red mid-September through mid-October, and the Warrens Cranberry Festival — September 25 to 27, 2026 (53rd annual) — draws 170,000 visitors to what the town calls the world's largest cranberry festival. Free admission, 1,300+ booths, marsh tours, and the ice cream parlor at the Discovery Center make it a legitimate family day.

Winter: ice, skis, and Wisconsin's clearest underwater viz

Winter may be the quietly best season for outdoor range. The Smrekar and Wildcat trail systems are groomed for both classic and skate cross-country skiing across 22-plus miles, with Smrekar's heated warming shelter making it a forgiving day out for kids. A Wisconsin State Trail Pass ($5/day or $25/year) is required. Wazee itself holds 11 miles of ungroomed ski trails around the lake for quieter outings. Dedicated snowshoe trails leave from the Smrekar lot (1.6 miles total). Snowshoers are welcome anywhere in the state forest except on groomed ski tracks. Snowmobilers get access to Jackson County's 300-plus miles of groomed trail connecting to the statewide system.

Ice fishing on Wazee targets trout, bluegill, perch, crappie, smallmouth bass, and walleye. Sherwood Forest Landing is the preferred access point because the walk to deep water is under 50 yards. Deep spring-fed lakes with current can ice over unevenly, so check thickness locally — the DNR recommends a minimum 4 inches of clear ice for foot traffic and 5 to 7 inches for snowmobiles, and it does not monitor individual lakes. Shanties must be removed by the last Sunday in March (Jackson County is in the Northern Zone) and must display owner identification.

Scuba divers who can handle cold water will find Wazee's best visibility of the year in winter — up to 60 to 100 feet — though dry suits and experience at depth are non-negotiable. Downhill skiers and tubers head to Bruce Mound Winter Sports Area in Merrillan; the hill runs Friday nights 5 to 10 and Saturday/Sunday/holidays 10 to 4, December through March. The local sledding hill is at Lunda Park in Black River Falls.

Winter camping is possible at Castle Mound (some sites plowed, electric available) and Pigeon Creek (rustic, water systems shut off). East Fork closes after mid-October. Pack layered clothing, insulated waterproof boots, wool socks, mittens with liners, hand warmers, and — if you're ice fishing — a bucket, auger, flasher, and shanty.

Planning the trip from Milwaukee

Drive time is about three hours door-to-Wazee via I-94 West to Exit 116, with Madison, Wisconsin Dells, and Tomah as natural break points. A weekend works better than a day trip; families doing the round trip in one day spend more time driving than recreating.

For non-camping lodging, the newly renovated Ho-Chunk Gaming hotel is ten minutes from Wazee and the most kid-friendly casino-adjacent option in the area (the hotel and restaurants don't require gambling). Chain options near I-94 include Best Western Arrowhead Lodge & Suites, Holiday Inn Express, Quality Inn, Comfort Inn, and Coratel. Family-friendly restaurants in Black River Falls include Cozy Corner (breakfast and comfort food), Sand Creek Brewery, Rozario's (pizza), and the reliable Wisconsin road-trip standby, Kwik Trip.

Medical care consolidated in late 2024: the former Black River Memorial Hospital and Krohn Clinic merged into Black River Health at 610 West Adams Street (715-284-4311), a 25-bed critical-access hospital with a 24/7 ER. Larger specialty hospitals are in La Crosse (Gundersen, 40 miles) and Eau Claire (50 miles).

Bottom line

The best single weekend of the year at Wazee is the last weekend of September or first weekend of October — fall color near peak, water warm enough for a brave swim, camping available, few bugs, and the cranberry festival 25 minutes down the road. The best summer weekend is mid-to-late June, before deer flies arrive and after black-fly season ends. The best winter weekend is late January, when the ski trails are groomed, ice is reliable, and scuba divers see 80 feet through the quarry walls.

Bring your own food, bring a dive flag if you're diving, bring blaze orange in the fall, and bring a paper map because cell coverage drops off fast in the state forest. Verify current fees by phone before you leave — Jackson County has been updating its fee schedule, and published amounts vary between $3 and $5 daily. The drive is long, but the payoff — a clear 355-foot lake, an easy 6-mile family loop, and 200,000 acres of public land at your doorstep — is a harder combination to find in southern Wisconsin.
