Adams County is expanding it's trail system as land and monies become available. Petenwell Park, on Wisconsin's 2nd largest inland body of water, will be constructing an ATV/UTV campground with access to Adams County's State funded trail system with anticipated opening in spring/summer 2017. Many ATV/UTV road routes consisting of sand, gravel, and/or pavement also exist in Adams County, and are open year round.
