Grand Canyon National Park Bicycling
Bicycles are not available for rent inside the park. If you plan to bring a bicycle, be aware that in Arizona bicycles are subject to the same traffic rules as automobiles. Use extreme caution when riding on park roads! Shoulders are narrow and vehicle traffic is heavy.
Bicycles are permitted on all paved and unpaved park roads and the new Greenway Trail. They are prohibited on all other trails, including the Rim Trail. Bicyclists must obey all traffic regulations. Always ride single file with the flow of traffic. See and be seen; wear bright colors and a helmet.
This road is open to bicycles throughout the year, but be aware that during the summer months there is heavy bus traffic. Hermit Road is narrow and bicyclists should pull to the right shoulder of the road and dismount when large vehicles are attempting to pass. Never hang on to a shuttle bus while riding.
Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
