Grand Canyon National Park - General Park Information

A powerful and inspiring landscape, the Grand Canyon overwhelms our senses through its immense size; 277 river miles (446km) long, up to 18 miles (29km) wide, and a mile (1.6km) deep.

Camping on the rim within Grand Canyon National Park is permitted in designated campsites only and violators are subject to citation and/ or fine. There are vehicle accessible campgrounds in Grand Canyon Village on the South Rim, at Desert View and on the North Rim.

Going on a hike is wonderful way to experience some of the canyon's rich natural beauty and immense size. However, even if you are an avid hiker, hiking the Grand Canyon is very different from most other hiking experiences.

Mental attitude and adequate water and food consumption are absolutely essential to the success of any Grand Canyon hike, particularly in summer. The day hiker and the overnight backpacker must be equally prepared for the lack of water, extreme heat and cold, and isolation characteristic of the Grand Canyon.

Hiking in the Grand Canyon is so demanding that even people in excellent condition often emerge sore and fatigued. Yet small children, senior citizens, and people with physical disabilities have successfully hiked the canyon.

A hike into the Grand Canyon will test your physical and mental endurance. Know and respect your limitations. Moderation is the key to an enjoyable hike.

Summer temperatures on the South Rim are relatively pleasant. North Rim temperatures are a few degrees cooler due to the higher elevation. Inner canyon temperatures are extreme. Daytime highs at the river often exceed 105°F. Thunderstorms frequently occur during July, August, and early September.

Winter conditions on the South Rim can be extreme. The road into the North Rim is closed from the first heavy snow in November or early December to mid-May.

Spring and Fall. Come prepared for a variety of conditions. Pleasant weather can change to rain or cold.
