Cyclists - As their popularity develops, you can expect to encounter mountain bicycles on the trail. Cyclists should know, however, that all wilderness areas are closed to bicycles. Where they are allowed, cyclists should strictly follow the backcountry ethics that follow, especially in regard to trail use. Cyclists should similarly obey the courtesy of allowing hikers (as well as horse-back riders) the right-of-way, just as vehicles do on city streets. If you are traveling through any area with a limited field of view be sure that your ability to stop quickly is maintained at all times.
