Vehicle traffic is heavy most of the time. There are no bicycle paths along roadways. We strongly recommend that safety gear, including helmet and high visibility clothing, be worn by all bicyclists. During April, May, and June, high snowbanks make travel more dangerous. Motorists frequently do not see bicyclists or fail to give them sufficient space on the road.
Drivers sometimes pass on hill crests, blind curves, or in oncoming traffic.
Vehicles, especially motor homes or those towing trailers, may have wide mirrors, posing an additional hazard. For more information about bicycling, stop at a visitor center. Bicycling Routes Several gravel roads are open to BOTH bicycle and automotive traffic. These roads are best suited for mountain bikes. Please do not block entrance gates when parking at these locations.
