Dillon Reservoir has a popular 18-mile paved bike path that winds around the entire reservoir. The path can be accessed at any point around the reservoir. Starting in Frisco and going clockwise, it goes behind the Summit Middle School, marshlands, and continues across the Dam road. It passes the towns of Silverthorne and Dillon. Once into Summit Cove subdivision, the path climbs over Swan Mountain and reaches its highest elevation of 9,500′ above sea level at the top at Sapphire Point, which is 1,100′ above the lowest point of the bike path. This is a popular lookout over Dillon Reservoir and much of Summit County. The path dissolves into the road on the other side. Bikers and cars must share the road. At the bottom, the path resumes near Summit High School. The path goes behind the hospital and back into Frisco.
