When the snow melts and you are lucky enough to find yourself in Keystone for the summer months, the Keystone Bike Park is the place to hang out for some real thrills on two wheels. Offering outstanding seasonal recreation for mountain bikers of all ability levels, the park includes 55 downhill trails for charging down the mountain. There are big jump features and rock gardens for the experts, clinics and lessons for the novices. Gear rentals are at nearby Keystone Sports in River Run Village. A bike-haul ticket is required to put your bike on the lift, and you can purchase that in River Run Village also.
