In 2006, the park saw initiation of an International Mountain Bicycling Association (IMBA) trail improvement project. The trail system earned the IMBA's "Epic" designation in 2009. In 2009, Wyoming began a program to build additional hiking trails in several Wyoming state parks. Curt Gowdy State Park served as the pilot project for the program, with 32 miles of additional trails. The state required that the newly built trails do not fundamentally alter the landscape of the park. Funding for the trails came from federal and state funds and private donations.
