Canyonlands National Park is made up of three sections: Island in the Sky, The Maze, and The Needles. Island in the Sky, the section we visited, is the most accessible. From Moab, take Highway 191 north to Highway 313, then follow signs to the park.
Once you arrive in the Islands in the Sky section, check out the visitor center. There you can get information about the hiking trails. You will also find restrooms there. If you walk across the street, there is an overlook with a beautiful view.
While in Canyonlands, we hiked a one-mile moderate trail to Upheaval Dome. It was worth it. We also hiked the .5 mile trail to Mesa Arch, an arch on a cliff edge. Green River, Grand View Point, and Buck Canyon overlooks also presented great photo opportunities.
Fuel up in Moab. I don't remember seeing any facilities on Highway 313. Also, food isn't available on 313 or in the Island in the Sky section.
Admission is $10/car. Admission is included if you have a National Park Pass.
