Where and Tips
Amazing natural arches and surreal landscape where you have to hike to. The arches are not visible from the road. Roads are mostly paved and can get crowded in peak summer months.
There are more than 2000 arches in the park. The origin started more than 65 million years ago, when the area was a dry seabed. The arches are made out of sandstone. The park receives not much rain but unfortunately, it’s enough to let erosion work at this kind of sandstone. Every arch will collapse someday like the Wall Arch on August 4 in 2008. Landscape Arch could be the next famous one.
