A great place! The park is just $6 per car to hike the trails or participate in their programs. It is very family friendly, be sure to check their calendar. They offer kids classes daily about hiking, full moon hikes, scorpion hunts, movies, etc.!
They have an ADA accessible trail, and have the Wind Cave trail (800 ft elevation change) that has scenic views from the top. We have also done their Yoga in the Desert classes on Saturday mornings, which is a lot of fun.
