Island in the Sky

Mesa Arch and sunrise timing

Mesa Arch is the most photographed location in Canyonlands and the reason many visitors arrive at the park before dawn. The arch sits at the very edge of the mesa rim: a 27-foot sandstone span framing a view of the canyon more than 1,000 feet below. You can see it at any time of day, but sunrise does something specific to it.

At sunrise, the sun rises behind you from the east and its first light reflects off the canyon floor below the arch and illuminates the underside of the sandstone from below. For about 10 to 15 minutes, the bottom of the arch glows deep orange while the sky behind it is still blue. The effect requires clear skies and the sun being close to the horizon, which makes it most reliable from March through October when the sun rises far enough north to clear the canyon walls at the right angle.

Sunrise timing by month

The following arrival times are approximate guides for when to be at the arch before the light arrives. Sunrise time shifts by roughly 2 minutes per day across the year.

• October: sunrise ~7:10-7:20 a.m. (MDT). Aim to arrive at the trailhead by 6:15-6:30.
• September: sunrise ~6:45-7:10 a.m. Arrive by 6:00.
• March-April: sunrise ~6:30-7:00 a.m. Arrive by 5:45.
• May: sunrise ~6:00-6:30 a.m. Arrive by 5:15-5:30.
• June-July: sunrise ~5:45-5:50 a.m. Arrive by 5:00.
• December-January: sunrise ~7:30-7:45 a.m. (MST). Less dramatic effect in winter because the sun is lower and more southerly; the canyon light doesn't reflect as strongly.

Logistics

The trailhead parking lot is 6 miles from the visitor center on the main paved road. The trail itself is a 0.5-mile flat loop on packed gravel, taking about 15 minutes to walk. On busy spring and fall weekends, the parking lot fills 60 to 90 minutes before sunrise. An overflow pullout on the road handles the spillover on the busiest days; add a 5-minute walk to the trailhead from there.

At any other time of day, Mesa Arch is a 20-minute round trip. The view of the canyon through the arch framing is worth the walk regardless of the hour, and the crowds are significantly lighter after 9 a.m.

Grand View Point

Grand View Point is at the southern end of the paved scenic drive, 12 miles from the visitor center. At 5,820 feet, it is the highest accessible point in the district and the best canyon panorama in the park. On a clear day, the visible horizon is around 100 miles in every direction: the White Rim sandstone bench below, the Colorado River more than 1,000 feet down, the Needles district visible as a band of orange spires on the southern horizon, and the La Sal Mountains rising above the canyon rim to the east.

A 2-mile round-trip trail follows the mesa rim from the parking area to the southernmost promontory. The trail is easy on a flat, rocky surface with no significant elevation change. At the end of the drive, a paved path leads 100 yards to an accessible overlook above the main canyon, and es suitable for strollers and wheelchairs. The 2-mile rim trail begins here and extends further, adding a second, slightly closer viewpoint over the confluence of the Colorado and Green Rivers.

Rangers give geology talks at Grand View Point on spring and fall afternoons. Check the program schedule at the visitor center or the NPS Canyonlands website. No shade exists on the 2-mile trail. In summer, do it early or late.

Other overlooks along the scenic drive

Shafer Canyon Overlook

One of the first pullouts after the entrance station, with a view down the Shafer Trail switchbacks. The Shafer Trail descends 1,500 feet in a series of hairpin turns cut into the sandstone cliff face. It was originally used by cowboys to move cattle between the mesa top and the grazing land below; now it is the primary vehicle descent to the White Rim Road. With a high-clearance 4WD vehicle and off-road experience, you can drive down it. Without one, watching other vehicles negotiate the switchbacks from the overlook is its own attraction.

Green River Overlook

A 100-yard paved path from the parking area to a rim-top viewpoint directly above the Green River, which flows far below in a canyon carved into the White Rim level. The Green River joins the Colorado 4 miles to the south, and on a clear day you can see the confluence zone. The overlook is accessible, takes about 5 minutes round trip, and is one of the best spots in the park to see the river's true scale relative to the canyon walls surrounding it.

Buck Canyon Overlook

A short walk from the parking area to a viewpoint above Buck Canyon, a side canyon that drains into the Colorado. Less visited than Grand View Point, it offers a different perspective: looking down a narrower canyon rather than across the full plateau. A good stop if you have time after Grand View Point and before driving back.

All hikes in Island in the Sky

Most trails in Island in the Sky start at mesa-top level and stay there, offering rim views throughout. The exceptions are Gooseberry Canyon, which descends steeply off the mesa to the White Rim, and the lower sections of some trails that drop into shallow drainages before climbing back to the rim. No shade exists on any of the mesa-top trails.

Trailhead parking areas are marked on the NPS map available at the visitor center. Water is only available at the visitor center. Carry at least 1 liter per hour per person on any hike from May through September, more in July and August.

Guided tours

Island in the Sky is easy to explore independently: a standard paved road reaches every overlook, and the trails are well-marked. Guided tours make sense if you want access to backcountry terrain that requires a 4WD vehicle, commentary on the geology, or a combined itinerary that covers Island in the Sky, Arches, and Dead Horse Point in a single organized day.

White Rim Road

The White Rim Road is a 100-mile dirt loop that circles the Island in the Sky district at a lower elevation, running along the White Rim sandstone bench approximately 1,200 feet below the mesa top and 1,000 feet above the rivers. It is one of the most famous 4WD routes in the American Southwest and a classic multi-day mountain bike circuit.

Completing the full loop requires 2 to 4 days depending on pace and vehicle. A high-clearance 4WD vehicle with a low-range gear is required for the vehicle route. Mountain bikers must be self-sufficient: no services exist anywhere on the road. Designated campsites must be reserved in advance through Recreation.gov at $36 per night plus $5 per person per night.

The main access point from Island in the Sky is the Shafer Trail, which descends 1,500 feet via switchbacks to the White Rim level. From the top at the Shafer Canyon Overlook you can see the first set of switchbacks. The road is maintained by the NPS but is subject to closure after significant rain, which can make sections impassable even in a 4WD vehicle. Check current conditions at the visitor center before attempting the Shafer descent.

Day trips onto the White Rim are possible if you do not need to complete the full loop. The first few miles down Shafer and along the White Rim bench give a completely different perspective on the landscape compared to the mesa-top overlooks.

Aztec Butte and the Ancestral Puebloan granaries

The Aztec Butte Trail starts flat, then climbs sandstone slickrock to the top of the butte. Near the summit, the trail splits. The left fork leads to two Ancestral Puebloan granaries tucked into a rock alcove just below the butte's rim. These small stone structures were built by farming communities who inhabited the Colorado Plateau between approximately 600 and 1300 CE. They stored dried corn, beans, and squash here, placing the food storage above the canyon floor where it was safer from weather and animals.

The right fork continues to the top of Aztec Butte for views down into Taylor Canyon to the north and across the mesa top. Both forks together add about 0.5 miles to the base trail distance. The granaries are the most tangible evidence of human habitation in Island in the Sky and worth the scramble to reach them. Stay on the trail and do not touch or enter the structures.

Upheaval Dome

At the northwestern end of the district, Upheaval Dome is an anomaly in the surrounding landscape: a circular depression roughly one mile in diameter with a central rock pinnacle, completely unlike the layered canyon walls everywhere else in Island in the Sky.

Two competing theories explain it. The meteorite impact hypothesis proposes that an asteroid struck here approximately 170 million years ago, compressing and then rebounding the underlying rock into the current dome shape. The salt anticline hypothesis argues that a massive salt deposit deep underground pushed upward over millions of years, deforming the overlying rock layers and then partially collapsing as the salt dissolved. The meteorite hypothesis has gained support in recent decades after researchers found shocked quartz in the area, a mineral that forms only under the extreme pressures of an impact event. The question is not definitively settled.

The Crater View Trail to the first overlook is 1.8 miles round trip and gains 330 feet. A second, higher overlook adds 0.25 miles and gives a wider perspective on the entire structure. The parking area is at the end of the Upheaval Dome Road, a spur from the main scenic drive.

Willow Flat Campground

Willow Flat is the only campground in the Island in the Sky district. It has 12 sites, all first-come, first-served at $15 per night. The campground is open year-round. There are no hookups, no showers, and no water at the campground itself. A vault toilet is on site.

Fill water at the visitor center before driving to the campground. The campground is 6 miles from the visitor center on a paved road, and the Green River Overlook is adjacent to the campground access road.

In spring and fall, sites fill on weekends by midday Friday. Arriving on a Thursday afternoon is the safe strategy for a spring or fall weekend. In summer, the extreme heat reduces competition for sites, but midday is still the worst time to arrive. Camping here puts you on the mesa for both sunrise and sunset without the 45-minute commute from Moab, which makes Mesa Arch sunrise significantly more manageable.

For campgrounds closer to Moab, the BLM-managed sites along the Colorado River corridor on Highway 128 are the most practical alternative. See the Moab camping guide for a full comparison.

Combining Island in the Sky with Dead Horse Point

Dead Horse Point State Park shares the same road as Island in the Sky: both are accessed via UT-313 from US-191 north of Moab. At a junction 14 miles from the highway, the left fork goes to Dead Horse Point (9 miles) and the right continues to Island in the Sky (18 miles). The two parks are about 20 minutes apart and work well as a single day trip from Moab.

Dead Horse Point sits at the tip of a narrow mesa 2,000 feet above a Colorado River gooseneck bend. Its distinctive feature compared to Island in the Sky is the view of the turquoise evaporation ponds used by a potash mining operation on the canyon floor, which add an unusual industrial contrast to the red rock canyon. Entry costs $20 per vehicle (2 consecutive days) and the America the Beautiful annual pass is not accepted there.

The standard Moab day trip runs Dead Horse Point in the morning for the best light on the ponds, then drives 20 minutes to Island in the Sky for the afternoon and early evening. From Moab, budget the first departure of the day for Dead Horse Point (it's on the same road, so no backtracking).

Getting to Island in the Sky

From Moab, drive north on US-191 for 10 miles. Turn left (west) onto UT-313. Follow UT-313 for 22 miles southwest to the park entrance. The drive from Moab is approximately 32 miles total and takes 40 to 45 minutes.

No GPS correction needed, but the NPS specifically warns that navigation apps sometimes route drivers the wrong way on UT-313 or onto unpaved roads. Use the map from the visitor center if you have any doubts about the route.

Gas: There is no fuel anywhere on UT-313 or inside the park. Fill up in Moab before departing. Moab has multiple gas stations on Main Street and US-191.

Cell service: Service is limited or absent on UT-313 beyond the first few miles and inside the park entirely. Download any maps or tours for offline use before leaving Moab.

Food and water: No food is sold in the park. Water is available at the visitor center only. Pack everything you need before entering. For full-day visits, a minimum of 3-4 liters of water per person in summer is the practical baseline.

Dead Horse Point junction: At mile 14 on UT-313, a signed junction splits left to Dead Horse Point and right to Island in the Sky. If combining both parks, see the section above for the recommended sequence.
