22 percent increase from the prior year. The geography of the park is well suited to a number of different recreational uses. Hikers, mountain bikers, backpackers, and four-wheelers all enjoy traveling the rugged, remote trails within the Park. The White Rim Road traverses the White Rim Sandstone level of the park between the rivers and the Island in the Sky. Since 2015, day-use permits must be obtained before travelling on the White Rim Road due to the increasing popularity of driving and bicycling along it. The park service's intent is to provide a better wilderness experience for all visitors while minimizing impacts on the natural surroundings. , the Island in the Sky district, with its proximity to the Moab, Utah area, attracts 76.7 percent of total park visitors. The Needles district is the second most visited, drawing 20.7 percent of visitors. The remote Maze district accounts for only about 1.5 percent of visitors, while river rafters and other river users account for the remaining 1.1 percent of total park visitation.

Below the Confluence, Cataract Canyon contains powerful whitewater rapids, similar to those found in the Grand Canyon. However, since there is no large impoundment on the Colorado River above Canyonlands National Park, river flow through the Confluence is determined by snowmelt, not management. As a result, and in combination with Cataract Canyon's unique graben geology, this stretch of river offers the largest whitewater in North America in heavy snow years. Political compromise at the time of the park's creation limited the protected area to an arbitrary portion of the Canyonlands basin. Conservationists hope to complete the park by bringing the boundaries up to the high sandstone rims that form the natural border of the Canyonlands landscape. On March 27, 2020, Canyonlands National Park was closed to help prevent the spread of COVID-19. Geography The Colorado River and Green River combine within the park, dividing it into three districts called the Island in the Sky, the Needles, and the Maze. The Colorado River flows through Cataract Canyon below its confluence with the Green River. The Island in the Sky district is a broad and level mesa in the northern section of the park, between the Colorado and Green rivers. The district has many viewpoints overlooking the White Rim, a sandstone bench below the Island,
