Best Times to Visit Arches National Park

The best time to visit Arches National Park is April through May and September through October, when daytime temperatures average about 60 to 80 degrees. In the summer, temperatures can exceed 100 degrees, which can make exploring the park's trails very uncomfortable. In late summer, violent storm cells often cause flash floods which can be quite dangerous if you get caught unaware. Winter can be a lovely time to visit, with fewer crowds, though occasional snow and ice can make trails slippery. In addition, there are no ranger programs offered at that time. However, the visitor center is open daily.

April-May

Weather-wise, this is great time to visit before the scorching days of summer descend. Expect temperatures in the lows 80s and 70s. For that reason, it's also a very popular time to visit. Be prepared for crowds and lines to get into the park. Rangers offer free, daily guided 1-mile walks along easy trails; check with the visitor center for more information on specific trails.

Key Events:

June-August

Despite temperatures that can rise above 100 degrees, summer is still high season for the park, when kids are out of school and families go on vacation. Every visitor should have plenty of water and be dressed for the weather, with a hat and lots of sunscreen. Visiting very early in the morning or in the late afternoon is one strategy to avoid the crowds and the blazing sun. What's more, rangers lead free guided evening walks in the summer.

Key Events:

September-October

Like April and May, September and October offer cooler, pleasant temperatures with highs in the mid-80s and 70s and lows in the 50s and 40s. Thanks to the mild weather, falls is another popular time to visit, so be prepared for crowds.

Key Events:

November-March

With temperatures in the 30s to 50s, visiting in winter can be a chilly proposition. That said, there are fewer tourists to contend with, so visitors don't have to compete for parking or be crowded on trails. There are two things to be aware of though: there are no ranger programs offered in winter and some roads and trails may be closed due to snow or ice.
