Arches in December.

Crowd snapshot.

December's five-year average of roughly 49,000 recreation visits makes it the second quietest month after January, about 25% of May. NPS describes winter as the park's peaceful season, free of the crowds and heat of summer, and December is where that is most obvious. The visitor center runs 9 a.m. to 4 p.m. and closes on December 25. Devils Garden has 25 first-come, first-served sites, with Scan and Pay through the Recreation.gov app. There are no services inside the park, so food, gas and supplies come from Moab, 45 to 60 minutes from the campground. In winter the bookstore sells firewood directly rather than through coupons.

Weather snapshot.

The Moab station records a December normal high of 43.9°F and a normal low of 22.0°F, a shade above January's 43.5°F and 21.4°F, with 0.76 inches of precipitation and 4.9 inches of snow. That snowfall figure is the station's highest, though NPS says large snowfalls are uncommon inside the park. When snow does land, the park road can close for a few hours while it is plowed, roads and pullouts stay icy in shaded stretches, and drifting snow can bury trail markers. Delicate Arch and Devils Garden turn slippery with packed snow and ice, and NPS recommends traction devices and trekking poles.

Access snapshot.

Arches never closes its gate, and 2026 asks for no advance entry booking (NPS news, February 18, 2026). The visitor center opens daily from 9 a.m. to 4 p.m. and shuts on December 25 (NPS Arches winter page). Devils Garden has 25 first-come, first-served sites; water taps are at the visitor center and the campground, and pit toilets stay year-round (NPS camping page). Ranger-led Fiery Furnace hikes do not run in winter, and a private permit is the only way in. A private vehicle pass is $30, card only (NPS fees page). For roads outside the park, NPS points to the Utah Road Weather Forecast or 1-866-511-UTAH. For the closures, entry delays and restrictions in force, read the NPS current conditions page.

Seasonal events.

December has the longest nights of the year, which suits a certified dark-sky park. The Geminid meteor shower falls in mid-December, and the darkest viewing comes at a new moon or once the moon has set. NPS names Balanced Rock Picnic Area, the Windows Section, Garden of Eden Viewpoint and Panorama Point, and notes the sky improves the farther north you drive from Moab. Daytime, low winter sun gives long light on the Courthouse Towers and Park Avenue walls for most of the day rather than an hour at each end. Snow on red slickrock is the one photograph you cannot plan for and cannot get any other month.

Audience verdict.

December is for people who want the park to themselves and do not mind the cold. Photographers get long shadows all day, the chance of snow on red rock, and the year's longest dark-sky nights. Campers get first-come sites at Devils Garden. It is a poor month for ranger programs, since none run, and the visitor center closes on December 25. Families can do the Windows, Park Avenue and the Delicate Arch viewpoint, and should carry traction devices if there has been snow. Bring everything from Moab, and check the visitor center's posted trail photos before choosing a route.

Methodology

Monthly recreation visits come from the official NPS Visitor Use Statistics Data Package, 2025 on NPS IRMA Stats; the statistic shown is Recreation Visits, the 5-year mean for 2021-2025. Climate normals come from NOAA NCEI's 1991-2020 U.S. Climate Normals at Moab, UT (station USC00425733, 4,053 ft elevation). Arches has no seasonal road closure, so the access score is 100 in every month. NPS said in February 2026 that no advance timed-entry reservation is required for 2026; Devils Garden Campground and Fiery Furnace hikes still need reservations.
