Islands in the Sky Cruise Professional Review and Guide
"Canyonlands National Park is a true showcase of Utah’s deep canyons, goosenecks, and buttes. The landscapes here are equally harsh, intimidating, intriguing, and alluring. There are five park districts, not all of which are accessible by paved roads. The Island in the Sky and Needles Districts are probably the most accessible to visitors. Relative to Moab, both Island in the Sky and Needles are to the southwest, although access to the former is from the northwest. The Island in the Sky District was selected for a road biking ride, in part, because it is closer to Moab than the Needles District and, in part, because Dead Horse Point State Park is adjacent. Thus, it is possible to integrate two parks into one ride.
The Islands in the Sky Cruise is a 51-mile out-and-back ride over undulating terrain between and through Dead Horse Point State Park and Canyonlands National Park. The elevation ranges from 5,639 feet at Upheaval Dome, in Canyonlands National Park, to 6,184 feet on Big Flat, on SR 313 between the Canyonlands and Dead Horse Point Parks. The route is entirely on state highways and national park roads, so the pavement is generally smooth."
