Driving south of Moab on HWY191 stands an impressive roadside arch. Wilson Arch stands 46 feet tall and spans 91 feet wide. Park in the gravel lot, and climb on up!
The climb up is short - 10 minutes max - but it is across sand and slickrock. Make sure you have on appropriate footwear. Once you reach the top, you are rewarded with views of the valley below. Traversing the ground under the arch is easy, but if you have kids please hold onto them. I saw toddlers in Crocs running around alone. Just because it so easily accessible doesn't mean it's safe.
There's not much else to say about Wilson Arch other than to do it! If you're getting out of your car to take photos, you might as well climb up the arch!
