There's really no tourist traps in Arches; no commercial establishments of any sort. The photo shows the entry to Sand Dune Arch. To access you must squeeze yourself through the rock fins. Don't get trapped.
I visit Arches in 2003
Unique Suggestions: Do a lot of hikings. Just enjoy.
Fun Alternatives: Nearby is Canyonlands. The small city Moab is a nice place for staying a couple of days.
