Safety and Equipment
During summer, some roads undergo "chip and seal" work leaving loose, fine rock on the road. This can be very hazardous to the cyclist. The following gear is recommended: helmets; bright-colored, warm, waterproof clothing; and food and water.
Carry tools and spare parts, and inspect brakes for worn cables and pads.
Descents may exceed 20 miles (32.2 km) and elevation losses of 4,000 feet (1,219 km).
Summer Bicycles are allowed on park roads only.
Be aware park roads have narrow or no shoulders, and often carry heavy traffic. To minimize conflicts with vehicles, plan your ride for the early morning hours.
Try to be off the road in late afternoon when thunderstorms and lightening create serious hazards.
Winter Winter Roads open to bicycles:
Old Fall River Road (gravel surface) and Trail Ridge Road (paved) are open to bicycles early in the summer season (April), before they open to vehicles. Check with the park's Information Office regarding specific dates.
