Arches National Park warns of wildfire smoke, long entrance waits in 2026

Smoke from the Cottonwood Fire near Beaver reached Arches National Park on June 24, and air quality could be unhealthy in many areas inside the park over the next 24 hours. That made the usual Moab day-trip math a lot less forgiving: Arches is still open 24 hours a day, but entrance waits between March and October can top 60 minutes.

If you were aiming for Delicate Arch, Devils Garden, or any exposed desert scramble, this was not the day to go hard. Summer temperatures often exceed 100 F, and the smoke alert urged people to limit exertion outdoors. That mattered most on long hikes and open slickrock routes, where heat, sun, and poor air pile on fast.

The cleanest way in was before 8 a.m. or after 3 p.m. to avoid traffic. Arches does not require advanced timed-entry reservations in 2026, but busy days still bring temporary gate delays when the entrance line backs up to US 191. If the trailhead lot was full, do not park on vegetation or block roadways. Check the webcam before driving in, then return later if the line or parking looked jammed.

The smoke warning landed as the Southeast Utah Group tightened fire restrictions, too. Those rules took effect at 12:01 a.m. on Friday, June 26, banning open fires except in approved fire pits and grills at developed sites, limiting smoking to enclosed vehicles or paved areas without nearby vegetation, and banning fireworks on all federal public lands.

Reservations still applied for Devils Garden Campground and Fiery Furnace hikes.
