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!

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. Gates open at 8:00 am. Hikes take about an hour to complete and are typically on your own. You'll need to allow enough time for your hiking experience as trail guides will lock the gate at 2:00 pm No pets are allowed on the trails. Wear comfortable hiking attire, sun screen, and bug spray if you would like. Port-a-potties are available on-site.
