Park Avenue is one of the first stops after entering Arches National Park. If you have time there is an amazing two mile out-and-back hike that will take you down and through the canyon. The Park Avenue Overview is the trail start and the trail finishes at the Courthouse Towers. Unfortunately my daughter and I were ill prepared for such a hike on this hot summer day. Perhaps we can make a return trip to walk among natures skyscrapers.
