Wisconsin Bike Trails and State Trails

Overview

Wisconsin claims the distinction of hosting the country's first rail-to-trail conversion: the Elroy-Sparta State Trail, which opened in 1967 after the Chicago and North Western Railroad abandoned its Monroe County line. That 32-mile route from Elroy to Sparta set a pattern replicated across the state. Today, the Wisconsin Travel Guide counts more than 25 state trails managed by the DNR, covering nearly 700 miles of off-road riding, and those connect to hundreds more miles of county and municipal paths.

The trails fall into a few broad corridors. In the southwest, the Coulee Region trails form a connected network: the Elroy-Sparta links to the La Crosse River State Trail (21.5 miles west toward La Crosse) and the 400 State Trail (22 miles east to Reedsburg), so an ambitious rider can string together 75-plus miles across three separate trails without touching a paved road. In south-central Wisconsin, the Military Ridge State Trail runs 40 miles from Dodgeville through Mount Horeb to Verona, where it meets Madison's local path network, and the Glacial Drumlin State Trail picks up near Cottage Grove and runs 52 miles east to Waukesha through glacial lake country. The Great River State Trail follows the Mississippi River corridor for 24 miles between Onalaska and Trempealeau, close enough to the bluffs that you can watch bald eagles working the backwater channels below. Up in the Northwoods, the Bearskin State Trail connects Minocqua to Tomahawk over 18.5 miles of Oneida County forest. The longest single trail is the Tuscobia State Trail, a 74-mile multi-use corridor running from Park Falls to Rice Lake through Rusk and Price counties.

What to Expect

Most Wisconsin state trails are crushed limestone, which is smooth enough for hybrid or mountain bikes and manageable on road bikes with wider tires. A few key trails are paved: the Military Ridge is mostly asphalt, and sections of the Glacial Drumlin are paved as well. Trail grades are gentle almost everywhere. The railroad engineers who graded these routes in the late 1800s kept slopes under two percent, which means even casual riders can cover 20 to 30 miles without feeling wrecked at the end. That gentle grade is one reason the Elroy-Sparta attracts as many first-time rail-trail riders as seasoned cyclists.

The signature feature of the Elroy-Sparta is its three unlit tunnels: the Elroy Tunnel (a quarter mile), the Wilton Tunnel (a half mile), and the Norwalk Tunnel (three-quarters of a mile). All three were blasted through limestone ridges in the 1870s and stay around 50 degrees year-round. Bring a light and a layer even in July. Riders walk their bikes through the tunnels, and most groups stop to let their eyes adjust and take photos before continuing. Between Elroy and Sparta, the trail passes through the villages of Kendall, Wilton, and Norwalk, each with a diner or tavern within a short walk of the trailhead.

Door County offers a different kind of bike experience. The Ahnapee State Trail runs about 30 miles from Algoma through Forestville to Sturgeon Bay on a flat rail corridor, making it a practical add-on during a Door County weekend. Many visitors also ride the county roads between peninsula villages, the Bay Shore Drive between Egg Harbor and Sister Bay is low-traffic, with orchard views and Lake Michigan glimpses. Cycling is popular enough in Door County that several shops in Fish Creek and Sturgeon Bay rent hybrid bikes and e-bikes by the day.

Trail towns are a real part of the experience. The Elroy-Sparta and La Crosse River trails converge near La Crosse, where Buzzard Billy's on Pearl Street is a consistent local stop for post-ride catfish and cold drinks. On the Military Ridge corridor through south-central Wisconsin, Verona and Mount Horeb have cafes and bars at the trailheads, and Madison is only a short ride from the eastern terminus. The Old Fashioned on Capitol Square in Madison is the right place to end a Military Ridge-to-Madison day with cheese curds and a brandy old fashioned. Near the 400 State Trail's eastern end, Ishnala Supper Club on Mirror Lake in Lake Delton is worth the short detour for anyone spending a night in the Dells area after a ride. For a broader look at where to eat along trail routes, the Best Supper Clubs in Wisconsin guide covers the classics by region.

Best Season

The trails open when the snow is off and the limestone surface drains, typically late April to early May in southern Wisconsin and mid-May in the Northwoods. Peak season runs from Memorial Day through Labor Day, when trail towns are staffed, rental shops are open, and campgrounds along routes like the Elroy-Sparta fill most weekends. July and August are hot and humid across the state. Starting rides before 9 a.m. and planning on a midday break in a trail town makes the summer heat manageable.

September and early October are the best riding months. Temperatures settle into the 55-to-70-degree range, crowds thin noticeably, and the hardwood canopy over the Elroy-Sparta and Glacial Drumlin corridors turns red and gold. Fall color on the Great River State Trail, with the Mississippi bluffs changing above the backwater channels, is some of the best fall scenery in the state. The Elroy-Sparta corridor typically peaks in mid-October. For hiking the same corridors on foot, the timing is the same. Some Northwoods trails switch to snowmobile use after the first hard freeze, though a handful are groomed for fat bikes through the winter months.

Typical Costs (Estimates)

A Wisconsin State Trail Pass is required for cyclists age 16 and older on most DNR-managed state trails. The day pass runs approximately $5 and the annual pass approximately $25, both are estimates based on current DNR pricing and subject to change. Passes are available online through the Wisconsin DNR website, at self-pay stations at major trailheads, and at some local bike shops. A separate vehicle sticker is required if you park at a state park or recreation area trailhead, running approximately $8 per day or $28 for an annual pass. Some trailhead parking lots are free while others are fee areas, so confirm on the DNR website before you go.

Bike rentals in trail towns range from roughly $25 to $45 per day for a standard hybrid or mountain bike and $50 to $80 per day for an e-bike, based on estimated rates from shops operating along the Elroy-Sparta and in Door County. Helmets, locks, and handlebar bags are typically included or available as a small add-on. Multi-day rentals from the same shop reduce the per-day rate. If you are coming from Milwaukee or Madison and want to avoid loading bikes onto a car, renting at the trailhead town saves time: Sparta is the main hub for the Elroy-Sparta, Verona serves the Military Ridge, and Algoma or Sturgeon Bay covers the Ahnapee.

Camping at state parks and trail-adjacent campgrounds runs from approximately $17 to $32 per night depending on site type and hookups, with reservations required for summer weekends at popular parks. Budget lodging in trail towns (Sparta, Reedsburg, Elroy) runs roughly $80 to $130 per night. Door County rates are considerably higher, typically $150 to $300-plus in peak summer. Campsite reservations on state trails open six months in advance at reserveamerica.com and fill fast for July and August weekends.

How to Book

There is no reservation required to ride a Wisconsin state trail. Buy your trail pass before you go through the Wisconsin DNR's online store or pick one up at a staffed ranger station, then drive to any public trailhead. The Elroy-Sparta has parking in Elroy, Kendall, Wilton, Norwalk, and Sparta. Military Ridge trailheads are at Dodgeville, Blue Mounds, Mount Horeb, and Verona. Glacial Drumlin trailheads are at Cottage Grove, Lake Mills, Jefferson, Sullivan, and Waukesha. The DNR's trail map page publishes current surface conditions each spring.

Bike shops in trail towns typically do not require advance reservations for rentals on weekdays, but popular Saturday slots in July and August can run short of available bikes. Calling ahead on Thursday before a summer weekend ride is good practice. If you plan to camp along the route, booking at reserveamerica.com six months out is not overkill for the Elroy-Sparta corridor.

Wisconsin's trail network connects easily to other outdoor activities. If you are doing the Elroy-Sparta or 400 State Trail, the water parks of Wisconsin Dells sit about 30 miles from Reedsburg, which makes a solid two-day combination. Reedsburg is also the eastern terminus of the 400 State Trail, so you can ride out in the morning and be at a Dells resort by afternoon.
