Part 3 of the video provides a brief review of the Grand Canyon Hiking Information from parts 1 and 2 of this video program. If you wish to camp anywhere in the park, other than in developed campgrounds on the North Rim, South Rim, or Tuweep, you must obtain a permit from the Backcountry Information Center. Backcountry travelers must have their permit in their possession while in the backcountry. Once a camp is established, the permit must be attached to a pack, tent, or other equipment in plain view so it can be easily checked by rangers. Permits are valid only for the trip leader, itinerary, number of people, and dates specified on the permit. Permits for all overnight backcountry use must be obtained through the Backcountry Information Center at Grand Canyon National Park.
