They have also introduced fees for the fiery furnace hike and other activities. Arches has heavy visitation all year round. You won't find solitude here, but you can practice your foreign language skills with people from all over the world. I suspect that Arches will soon be going the way of Zion National Park in instituting a shuttle program where you park outside the park and ride in en masse with the other tourists. I'm not ready to predict what they'll do about campground access.
Arches is a beautiful site with the most naturally occuring arches in a given area.
There are also archaelogical and fossil sites in the park. Within the Desert Pleasure site, you can find information about some of the Arches backcountry sites, Delicate Arch , and soon, the Windows, The Grotto walk, Courthouse Wash hike, and the Fiery Furnace.
