Reservations can be made up to 6 months in advance at recreation.gov and at 877-444-6777. The North Rim Campground is open from mid-May to mid-October. It is operated by the National Park Service.
There are no hook-ups for RVs. However, there is a dump station within the campground. Pets are allowed but must be leashed at all times, and may not be left unattended. They are not allowed on the trails in the park.
Wood and charcoal fires are only permitted in provided campsite grills. No gathering of down wood is allowed. Wood may be purchased at the general store. Coin operated laundry and showers are located at the entrance to the campground. Accessible campsites and restrooms are available.
It is possible to check at the campground for the slight chance of drop-in availability.
A maximum of two vehicles, six people, three tents are allowed per site. (A vehicle, which is towing a trailer, pop-up, tent trailer, fifth wheel, or a motor home pulling a vehicle, is considered two vehicles.)
After mid-October, weather permitting, a limited number of campsites at the North Rim Campground with limited services (portable toilets) will be available on a first-come, first-served basis until snow closes Highway 67. Hikers and cross-country skiers will be permitted to use the park's group campsites throughout the winter months if they have obtained a permit through the park's Backcountry Information Center.
If you need a park map to get a sense for where everything is and to map out your hiking routes, you can purchase one of three Trails Illustrated maps covering different areas of Grand Canyon National Park at REI.com.
