Arches in March.

Crowd snapshot.

March averages about 144,000 recreation visits, roughly 74% of the May peak and the first month of the busy season. NPS asks visitors to enter ahead of 8 a.m. or past 3 p.m. for the lightest traffic, and it can temporarily delay entries when the entrance line reaches the highway or the parking lots fill. You can check the entrance backup live on the park's webcam. Devils Garden's reservation season opens March 1 and the campground is usually full every night; sites open six months out at 10 a.m. Eastern, with a last-minute window four days out. Two accessible sites exist: 4H held first come for people with disabilities, and site 7 reservable in season.

Weather snapshot.

The Moab station records a March normal high of 64.6°F and a normal low of 35.6°F, with 0.70 inches of precipitation and 0.2 inches of snow. This is the first month where the weather stops being the limiting factor and the crowd starts being it. Nights still drop near freezing, so shaded slickrock can hold ice into early spring on the Delicate Arch route. Rain or a late snow can turn the park's unpaved roads to four-wheel-drive condition or make them impassable, which is weather-triggered rather than seasonal. The main paved road has no seasonal closure window.

Access snapshot.

The gate never closes and 2026 asks for no timed-entry booking, though an entrance pass is required and can be bought online or at the station, card only (NPS Arches fees page). NPS recommends arriving before 8 a.m. or after 3 p.m. and may delay entries on very busy days (NPS hours page). Devils Garden takes reservations for nights from March 1 through October 31 on Recreation.gov, and is usually full every night (NPS camping page). Rangers normally offer Fiery Furnace hikes spring through fall, and the only way in is with a ranger or on an individual permit; the ranger-led hike is $16 per person and a private permit $10, with no children under 5. Backpacking uses four designated sites and needs a $7-per-person permit picked up in person south of Moab. For the closures, entry delays and restrictions in force, read the NPS current conditions page.

Seasonal events.

March is when the Fiery Furnace season normally starts. NPS runs ranger-led hikes daily spring through fall, and they require reservations. It is not a casual walk: the route crosses uneven surfaces, narrow ledges above drop-offs, loose sand, gaps you have to jump, and squeezes that need hands and feet against the rock. Children under 5 are not permitted on either the ranger-led hike or a private permit. Elsewhere, the soil-crust rule starts to matter as the crowds arrive. Stay on trails, slickrock or washes, because stepping onto crust can do damage that takes centuries to recover. Many trails here are marked only by cairns across broad rock, so follow them rather than making your own line.

Audience verdict.

March is the first month where Arches is both comfortable and fully running, and the crowd reflects that. Hikers get every trail in play without heat planning. Photographers get long shadows and clean air. Families get ranger-led Fiery Furnace hikes back on the calendar, with the age-5 minimum and a genuinely demanding route to weigh. The catch is reservations: Devils Garden fills every night, and Fiery Furnace needs booking. Anyone chasing quiet should aim at the first week of the month or wait for November. RV travelers should book six months out. Arrive before 8 a.m. or after 3 p.m., because the entrance line is now a real thing.

Common questions.

Is March a good time to visit Arches?

March runs busy at Arches, about 74% of the May peak, with mild shoulder-season weather (average highs near 65°F). It is one of the busier months, though not always the single peak.

How crowded is Arches in March?

How much of Arches is open in March?

In a typical March, about 100% of Arches's road network (weighted by how important each route is) is open to wheeled vehicles. Road-opening dates shift year to year, so check the official NPS page for current conditions before you go.

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.
