Canyonlands National Park is the largest national park in Utah. Its dramatic desert landscape has been sculpted over time by the Colorado River. It contains countless canyons, rock pinnacles, mesas, buttes, arches and spires. The park consists of four districts: the three land districts of Island in the Sky in the north (the most accessible and visited district), the Needles in the east (filled with backcountry roads and colourful spires) and the Maze in the west (the most remote and rugged district), and the Green and Colorado rivers that divide the park.
