Not really a cave to explore but really awesome to see. Reminds me of the video game Halo when you are about to go and drive under ground. Good area to walk around. Plenty of parking when we went. Trails are well marked.
Parking is hard to find in the area. There are a couple garages nearby though and the price isn't bad. Very pretty area to spend an hour or so.
Lots to do in the area of the Arch. Get tickets in advance. They sell out quickly. Takes 90 minutes to wait, get up in the arch and back down. We would do it again for sure. Traffic in the area is horrible so give yourself time for dealing with traffic. You'll want to spend a couple hours in the area.
This was impressive and met our expectations. It is part of a larger park, with great trails. They were restoring an old train engine at the park while we were there. If you are just driving through and needing a break, give yourself an hour, if not 90 minutes. You can spend half a day here easy.
