A 13.5-mile circuit of Presque Isle State Park. This paved, ADA accessible trail is popular with bicyclists, in-line skaters and joggers. During the winter, the trail is plowed from the entrance to the park office for hikers. For cross-country skiers, the trail is left snow covered from the park office to Perry Monument. The trail was renamed in 2003 for the late State Representative Karl Boyes.
