Things to Do

Check out our Things to Do page for ideas in planning your visit. This page will tell you about our Visitor Center Museum and Bookstore (open 9am to 5pm daily, 7 days per week), Park Movie, Entrance fee details, Tours, and Picnic Facilities. The typical park visit lasts 2 hours, but it really depends on what you are most interested in and conditions when you visit.

Special Events

Check out our Calendar page for special happenings and events going on in the park. There is generally more happening in the cooler fall and winter compared to the nice hot summer months. Past events include a Speakers Series, Arts Festival, Archeology Month Hand On Events, Demonstrations by Native American Artists and Craftsmen, Junior Ranger Day, Fee Free Days, and so much more.


Well behaved pets under physical control (usually a leash 6 foot long or less) are welcome. Please don't let your beloved companion stay in a vehicle where it can get very hot very quickly. You may NOT leave your vehicle running to provide air conditioning so bring your buddy with you. Don't forget to bring your equipment for cleaning up after your pet, too.

Fun for Families

Well behaved children can find some excellent adventures using the park Junior Ranger book and speaking with park volunteers. Scout groups who call and plan in advance may visit to earn patches, badges, knots, and many other awards. Look at the For Kids section for activities to do before your visit as well.
