Closed on: New Years, Thanksgiving, and Christmas days. The visitor center typically closes at 2:00pm on Thanksgiving and Christmas eve's.
Tons of fun and a nice hike! Easy to get to. It's a nice little hike through the Petroglyphs so I recommend a backpack carrier for younger kids. Very interesting to look at all the old writings on the petroglyphs.
Perfect for a nice day outside, exercise plus educational fun!
