Before you head out on your excursion, there are a few essential details. First, Arches National Park is one of the busiest in the country so make sure you have reservations prior or get to the park early to avoid any lines. To better understand reservations, check out our article on the national park reservation system. The park does slow down during the winter months, so if you don’t mind a little cold, we recommend visiting then. Additionally, pets are not allowed on any trail because the park gets crowded and can have really high temperatures. We love having furry friends on the adventure, but they might have to sit out on this one. Lastly, try to read up on the science behind the arches. These rock formations are something to behold.
