A Special Use Permit is required when any of these conditions exist:
Trail Ridge Road and Old Fall River Road
Trail Ridge Road is a paved highway that crosses the park from east to west. Elevations range from 7,800–12,183 feet, with 11 miles above treeline (see elevation profile below). Road shoulders are narrow, guardrails are few, and some drop-offs are steep. Trail Ridge Road and Old Fall River Road remain open to bicycles April 1 to November 30 (except during maintenance and emergency closures). However, the road is only maintained and regularly patrolled from Memorial Day weekend until the first major snow in mid-autumn; use at your own risk. When Old Fall River Road is open to vehicles, bicycles must travel in the same direction as traffic, which is uphill/westbound only.
Other Park Roads
Bicycles are prohibited on the Grand Ditch Road and on all trails except for a two-mile segment of the East Shore Trail near Grand Lake. E-bikes are prohibited on the Grand Ditch Road and on all trails including the East Shore Trail.
Bicycles and e-bikes are permitted on all roads open to motor vehicles (paved and dirt) unless otherwise posted. Roads are narrow with few or no shoulders and no designated bicycle lanes, so ride with care.
After autumn road closures:
Lodging, Rentals, and Facilities
There is no lodging in the park, and camping is allowed only in campgrounds. Bicycles are not available for rent in the park. Lodging and bicycle rental, repair, sales, and tours are available in nearby communities.
There are bike racks at visitor centers but no bike racks on shuttle buses. At trailheads, if no bike rack is available, cyclists may carry their bike into the woods and lock it to something out of sight (like a tree) as long as no harm is done to that object. Cyclists may not lock bikes to signs or trailhead bulletin boards.
If you plan to leave your bike overnight, you must get a dash tag from the Wilderness Office and tape it to your bike. Items left over 24 hours are considered abandoned. Permits are required for all overnight wilderness camping.
The park assumes no liability for bikes or other property left unattended.
Safety is your responsibility. Cycle at your own risk.
