At the Keystone Ancient Forest you'll hike amidst a classic Oklahoma cross timbers forest with 500-year-old cedars and 300-year-old post oak trees. Come out and take in all that this magnificent forest has to offer inside a 1,380 acre nature preserve listed by The Nature Conservancy as one of the last great places on earth!

Trail Ambassadors

Volunteer trail ambassadors help staff, monitor the parking lot, and hike the trails offering information and assistance. You can hike alone, or if there are enough trail guides available and you choose to, someone may hike with you to help interpret the forest landscape and this interpretative project in the making!

Guidelines

No reservations are needed.  Pets are allowed on select hike with your dog days. Wear comfortable hiking attire, sun screen, and bug spray if you would like.
