Officially, the North Rim  section of Grand Canyon National Park is open May 15-October 15, but it’s Mother Nature, not the Park Service, who really calls the shots. The Park Service closes the lodge and other facilities at the North Rim on October 15, but you can visit or camp until the first snowfall closes Highway 67.
Hardy Nordic skiers can get backcountry permits for winter camping or reserve the North Rim yurt, but for most of us, the time for outdoor recreation on the North Rim is limited to the sweet, brief summer and early fall.
Even in midsummer, nights can be cool, so bring some warmer clothes as well as a jacket for afternoon showers. Drink plenty of water and take some time to get used to the high elevation and low humidity before setting out on a challenging hike or ride.
You don’t need a permit for a day hike  or bike ride . The park’s website (www.nps.gov/grca ) and The Guide  offer many tips and suggestions for short meanders and full-day adventures. For overnight trips or winter camping, backcountry permits  are required.
The North Rim may lack some of the creature comforts offered by Grand Canyon Village  and the South Rim , but it offers a wider variety of recreational activities. If you like exploring the great outdoors, you’ll be glad you made the extra effort to get to this side of the canyon.
