Arches National Park: 2,000 Stone Arches and Counting

Start with the number: more than 2,000 documented stone arches packed into 76,000 acres of southeast Utah. The densest collection of natural arches on Earth. Then the stranger fact: the whole park is built on salt.

Three hundred million years ago a sea covered this corner of Utah, evaporated, and left behind a salt bed thousands of feet thick. Rock piled on top. Salt does something odd under that kind of weight. It flows. The rock above warped into domes, the domes cracked into parallel fins, and water and ice have spent millions of years whittling those fins into holes. In 1991 a 60-foot slab peeled off Landscape Arch while hikers watched. The park is mid-collapse. That's not a flaw. That's the show.

Know before you go: Arches sits 5 miles north of Moab, Utah, on US 191, and as of 2026 you do not need a timed-entry reservation. Pay the $30 vehicle fee (valid 7 days) at the gate and drive in, though gates can pause entries for a few hours when parking fills. Delicate Arch is a 3-mile round-trip hike with no shade, the Fiery Furnace requires a $10 permit reserved on Recreation.gov, and dogs are not allowed on any trail in the park. April, May, September, and October are the months you want; summer runs past 100 degrees.

Do you need a reservation for Arches in 2026?

No. After several years of timed-entry tickets, the park dropped the requirement for 2026. Pay at the gate and drive in.

One catch. On busy days, when the entrance line backs up to the highway or the trailhead lots fill, rangers temporarily close the gate and let the park drain. Waits at the entrance can pass an hour between March and October. The fix hasn't changed in a decade: be through the gate before 8 a.m. or after 4 p.m. Early gets you the light and an empty Windows section. Late gets you Delicate Arch at sunset, which is when that hike makes the most sense anyway.

The Fiery Furnace still runs on permits, and they sell out fast in spring and fall. Self-guided entry is $10 per person on Recreation.gov, bookable no more than 7 days out and no less than 2. Groups max out at six, kids under five can't enter, and every person on the permit has to show up at the visitor center for an orientation video before you go in. Ranger-led hikes ($16, spring through fall) are the better call for a first visit.

Camping is one campground: Devils Garden, 18 miles inside the park, $25 a night. Reserve for March through October, and reserve early, because it fills nightly all summer. Winter is first-come, first-served and quietly excellent.

What's it actually like inside?

One paved road, about 18 miles end to end, climbing from the visitor center into the good stuff. Park Avenue comes first, a mile-long wash between sandstone walls that Manhattan would recognize. Then Balanced Rock, 128 feet of physics dare. The Windows section is the best arch-per-step ratio in the park: North Window, South Window, Turret Arch, and Double Arch all sit within a mile of easy walking.

Delicate Arch is the one on the Utah license plate, and for once the symbol undersells the experience. The hike is 3 miles round trip up an open slickrock ramp, around a ledge, and into a bare sandstone bowl where the arch stands alone on the rim, 52 feet tall, framing the La Sal Mountains. No shade anywhere. Carry more water than feels reasonable. Sunset turns the whole bowl orange and draws a crowd that feels more like an amphitheater audience than a trail. Go anyway.

Devils Garden anchors the far end of the road. An easy 0.8 miles gets you to Landscape Arch, a 306-foot ribbon of rock that looks too thin to exist, because it nearly doesn't. Past it the maintained trail ends and the route gets interesting: slickrock spines, exposure, and a 7.9-mile primitive loop for hikers who want the park mostly to themselves.

The Fiery Furnace is the strangest hour in Utah. A labyrinth of fins with dead ends, drop-ins, and no marked exit, where GPS bounces uselessly off the walls. You will get turned around. With a ranger, that's the fun of it.

Can I do this with a dog?

Not on the trails. Arches bans pets from every trail in the park, even carried in a pack or sling. Where they can go: Devils Garden Campground, parking areas, and along the roads, including the unpaved Cache Valley and Willow Springs roads, always on a leash of 6 feet or less. In summer that's a worse deal than it sounds, since pavement here can blister paws by mid-morning and a parked car is lethal in minutes. Moab has boarding kennels; on a summer trip, your dog is happier there.

Bringing kids?

Arches is one of the easier parks to do with young kids, because the payoffs come fast. The Windows loop is under a mile with three huge arches. Sand Dune Arch hides in a shaded slot between two fins with a natural sandbox underneath it, the best kid stop in the park. Balanced Rock is a five-minute leg-stretch.

Delicate Arch with kids is a judgment call. Steady walkers of 8 and up handle it fine outside of summer heat; the final ledge section is narrow but short. The honest bailout is the Lower Delicate Arch Viewpoint, a flat 100-yard walk with a distant view of the arch. The Fiery Furnace draws a hard line for you: no children under five, and under-tens need real scrambling confidence.

Stay safe out there

Heat is the main event. Summer highs top 100, the rock radiates it back, and shade is close to nonexistent. The park's guidance is a gallon of water per person per day, and on the Delicate Arch trail in July that is not a suggestion. Slickrock grips like sandpaper when dry and turns to glass when wet or icy, so mind winter mornings and monsoon afternoons. Speaking of monsoons: July through September brings lightning, and an open slickrock bowl is the last place to be standing when it arrives. Watch the sky after noon. Climbing on any named arch is illegal, and cell service inside the park is a rumor. Tell someone your plan.

FAQs

Do you need a timed-entry reservation for Arches National Park in 2026?

No. Arches ended its timed-entry reservation program for 2026, so you can enter anytime with a standard pass ($30 per vehicle, valid 7 days). The park may still pause entries for a few hours on peak days when parking lots fill. Arriving before 8 a.m. or after 4 p.m. avoids the problem.

How hard is the Delicate Arch hike?

It's 3 miles round trip with about 480 feet of climbing, most of it up an open slickrock slope with zero shade, ending in a short ledge walk. Most hikers take 2 to 3 hours. In summer, go at sunrise or sunset and carry at least 2 liters of water per person.

Do I need a permit for the Fiery Furnace?

Yes. Self-guided entry requires a $10-per-person permit reserved on Recreation.gov between 7 and 2 days before your trip, with a group limit of six, no children under five, and no pets. Ranger-guided hikes ($16 per person) run spring through fall and are recommended for first-timers.

What is the best time of year to visit Arches?

April, May, September, and October offer mild temperatures and the best hiking weather, and they're also the busiest months. Summer regularly exceeds 100 degrees with almost no shade. Winter is cold but uncrowded, and snow on red rock is a photographer's cheat code.

Are dogs allowed in Arches National Park?

Dogs are not allowed on any trail in Arches, even carried. They are permitted in the campground, parking areas, and along park roads on a leash of 6 feet or less. In summer heat, boarding in Moab is the kinder option.

Scratch off park #18
