This review is for the trail across the road from the Marina near the spillway. The trail provides great access to a protected area with a lot of biodiversity. There is a vernal pool in the environmental education field that harbors spotted salamanders during their spring migration. There is a Great Blue Heron rookery near the standing water. Hikers can do a smaller section if they like. There is a huge Sycamore close to where you first take the steps next to Little Sandy. A nice mix of trees and native plants in the field. Lots of wildflowers, mushrooms, and wildlife. Mushrooms include oysters, milkies, chanterelles, hedgehogs, puffballs, beefsteak, chicken of the woods, hen of the woods, cauliflower, and plenty others. I’ve even seen a bear! Easy access from I-64 for anybody coming through Grayson.
