Canyonlands National Park is about 30 miles from Arches. It too has fascinating rock formations, but in some ways it’s a different experience. Part of the reason is that it’s more remote and so has fewer visitors.
The park has three sections that are not connected to each other: Island in the Sky, the Needles, and the Maze, which can be reached only by four-wheel drive or water.
We went to Island in the Sky, the most accessible. Island in the Sky is essentially a giant triangular plateau formed by the Colorado and Green Rivers, which meet at the southern end.
Like Arches, the photos really tell the story of Canyonlands.
