Arches National Park

Arches: Over 2,000 Natural Stone Arches in 76,000 Acres, and the Park Fills by 8am in Summer

Arches National Park in Utah contains the largest concentration of natural stone arches on Earth – over 2,000 formations in 76,519 acres. The Entrada Sandstone that produced them formed from ancient sand dunes compressed and cemented over 300 million years, then slowly undercut by salt dissolution below the surface. The resulting fins, arches, and balanced rocks are the colour of rust and brick, shot through with white and cream. Five miles north of Moab on the Colorado Plateau, the park has become one of the most visited in the American Southwest, which means the timed-entry reservation system is now mandatory during peak season.

The Essential Stops

Delicate Arch is the state symbol of Utah and the most photographed feature in the park: a 65-foot freestanding arch accessible via a 3-mile round trip hike with 480 feet of elevation gain across exposed slickrock. No shade, no guardrails. Go at dawn or two hours before sunset. The arch at sunset turns deep orange-red in a way that earned it its reputation.

Landscape Arch in the Devil’s Garden area is the longest arch in North America, spanning over 290 feet in a span so thin that geologists are watching it for structural integrity. A 1991 rockfall removed a significant slab from the span. The access trail is 7.6 miles round trip but the first 1.3 miles to the arch are easy.

Double Arch in the Windows Section consists of two arches joined at their base, accessible via a 1-mile paved loop. A textbook example of the parallel arch formation that distinguishes Arches from other Utah parks.

Fiery Furnace is a labyrinth of sandstone fins requiring either a ranger-guided permit or a self-guided permit, both bookable ahead through Recreation.gov. The formations create a maze of narrow passages and dead ends that makes it genuinely possible to get lost. The ranger tours run two hours and provide navigation and geological context that transforms the experience.

Practical Logistics

The park entrance at the junction with US-191 near Moab requires a timed-entry reservation from April through October, bookable up to 90 days ahead at Recreation.gov. The entry fee is $35 per vehicle (covered by America the Beautiful annual pass). The park fills to capacity by 8 to 9am on busy spring and autumn days; arrive at 7am or plan an afternoon entry. Winter (December through February) offers solitude, occasionally dramatic snow-dusted formations, and no timed entry requirement.

Devils Garden Campground, the only in-park camping, has 139 sites at $25-50 per night. Reservations open 6 months ahead and disappear within minutes for peak-season dates.

Moab, 5 miles south, is the service base with restaurants, hotels, and outfitters. Carry at least 3 litres of water per person for any hike longer than an hour. Slickrock is abrasive and hot; proper hiking boots matter more than they do in most parks. Download offline maps before you lose cell service, which happens throughout much of the park.

Combining Arches with Canyonlands National Park (30 minutes south) and Dead Horse Point State Park (20 minutes) makes a logical multi-day circuit of the Colorado Plateau canyon country that you won’t replicate elsewhere in the world.
