Elroy-Sparta State Trail

Considered the first rail-to-trail conversion in the country, the 32.5-mile Elroy-Sparta State Trail passes through three rock tunnels and five small towns. Walk-in-only campgrounds sit at each end of the trail - Sparta Campground and Elroy Campground - with fire rings, picnic tables, vault toilets, and hand-pump water; vehicles park in adjacent lots since there's no drive-in access to either campground. Wisconsin's own page does not publish a site count for either campground.

Wisconsin DNR statewide camping system: a vehicle admission sticker is required at every state park or forest entrance, including for registered campers - $28/year for Wisconsin residents ($13/year age 65+) or $50/year for non-residents, or $13/day resident / $16/day non-resident. Nightly campsite rates vary by electricity, amenities, location, site type, day of week and season, and are shown when you select a specific site during booking; non-resident campers pay a flat $15/night surcharge on top of the site's own rate. A $9.30 reservation fee applies per booking, plus a $10 cancellation fee or $6 change fee if plans change. Pets are allowed at this campground on a leash no longer than 8 feet at all times, per Wisconsin State Park System's statewide pet policy; owners must clean up and properly dispose of pet waste.
