Sparta Walk-In Campground is a primitive walk-in facility designed for trail users on the Elroy-Sparta State Trail, America's first rails-to-trails project.

Each site features a fire ring and picnic table, with hand pumps for water and vault toilets available; vehicles must be parked in an adjacent lot, making this a true walk-in experience ideal for hikers and bikers.

The campground operates seasonally (spring through fall) and reservations can be made online through the Wisconsin State Parks system, though be aware that highway noise from nearby I-90 can be significant.
