Hiking
Several short trails explore the mesa top with minimal elevation change, enjoying canyon views from above. Moderate trails involve elevation, such as climbing a sandstone feature or descending partway into a canyon. Long trails at Island in the Sky begin on the mesa top and descend via switchbacks to the White Rim bench, or beyond to one of the rivers. All are considered strenuous, with an elevation change of 1,000-2,000 feet, and require negotiating steep slopes of loose rock as well as sections of deep sand.
All trails are marked with cairns (small rock piles). Water is scarce; bring at least 1 quart (1 L) of water per person for short trails, and up to 1 gallon (4 L) for long trails. Avoid hiking during peak heat on summer days. Carry a flashlight, map, and basic first aid equipment.
