Keystone Ancient Forest

Keystone Ancient Forest
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 1,360 acre nature preserve listed by The Nature Conservancy as one of the last great places on earth! 

Deer, mountain lion, bobcat, American eagles, migratory birds, and over 80 varied species of butterflies inhabit this place. So enjoy, but please leave only footprints during your hike.


Open Thursday 7am-2pm, Friday-Sunday 7am-6pm

Property is locked promptly at closing time.

Dogs allowed the 1st weekend & 3rd weekend of each month.

Hike dates are subject to change due to weather! Please see our Facebook page for current updates and cancellations.

Trail Guides

Volunteer trail guides help staff the parking lot and monitor each hike event. 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!


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.
