About 30 miles. Curt Gowdy State Park is home to thrilling bike trails. The park is well marked with trail info at nearly every intersection, so it’s easy to craft your own journey through the terrain. The extensive single track system is at a lower elevation than Happy Jack and Vedauwoo, so trails are more clear of snow and winter debris. There are lots of obstacles, like log jumps, and heart-stopping vertical drops to keep you on your toes.
