Hidden Ponds Hike 

Join us for a guided tour of the wet areas of Thorn Creek Woods. Discover vernal ponds, listen for the return of amphibian choruses and explore the marshes of Owl Lake and beyond. These low lying areas provide vital habitat for woodland creatures and are an integral part of the Thorn Creek ecosystem. Participants will enjoy a 3-mile hike on natural surface trails across uneven terrain.
