The following list includes a set of rules established to protect both the park and its visitors (for more information, see the park's free publication, The Guide):
- Bicycles are allowed on all paved and unpaved park roads where motorized vehicles are permitted, and on the Greenway Trail. However, they are not allowed on hiking trails, including the Rim Trail. Bicyclists must obey all traffic regulations, and should ride single-file with the flow of traffic. On narrow Hermit Road, they should pull to the right shoulder and dismount when large vehicles are passing.
- It is illegal to remove any resource from the park. This covers anything from flowers to potsherds. Even seemingly useless articles such as bits of metal from the canyon's old mining operations have historical value to the park's users and are protected by law.
- Leashed pets are permitted on trails throughout the South Rim's developed areas, but not below the rim. The only exceptions are certified service animals.
- Fires are strictly prohibited except in the fire pits at North Rim, Desert View, and Mather campgrounds. In the backcountry, a small camp stove for cooking is acceptable.
- Discharging weapons -- including guns, bows and arrows, crossbows, slingshots, and air pistols -- is prohibited. So are all fireworks.
- If, by chance, you have a hang glider and are considering jumping into the canyon, forget it. It's illegal, and you'll be fined.
