Please stay on trail and do not go around muddy spots. If people go around muddy areas, the trail widens and vegetation is trampled. A widened trail is very difficult and expensive to restore. Thank you for helping to keep your open spaces beautiful!
The area around the Keyhole has an active bee hive. Please be cautious.

The trail has a potable water spigot at the trailhead, but offers no other water and little shade for miles. Please bring water for yourself and your pets and take care to bring sunscreen and a hat to protect your skin and face from the sun!
The new Hidden Valley Trail is OPEN!
The new trail is now open and accessible to bikers, trail runners and equestrian riders; however, no hikers are permitted on the Hidden Valley Trail.
Devil's Backbone is home to many species of snake, including Prairie Rattlesnakes. It is not unlikely for you to see a snake during the morning and evening when they are most active. If you encounter a snake, back away slowly and give it several feet of space to retreat. If you are bitten by a snake, stay put and call 911.
It is illegal to kill snakes at the Devil's Backbone.
