Petroglyphs and beautiful geology
This park is overlooked since it’s so far from everything (literally borders Mexico), but it’s very much worth the trip. There is wonderful natural history to learn about. Even if you can’t do a long hike the views are very pretty. There are a few options for campsites, including tent-only, but they’re all pretty similar in views.
Yay: fantastic hikes along and into canyons and caves, wildlife (lizards were cool), lots to learn. Picnic tables have nice shade (otherwise it’s very open).
Nay: they don’t have the tours of the petroglyphs every day and you can’t visit them on your own.
Surprise: this park is not huge but there is so much to do and learn. Bring a camera!
