The evening is a great time to search for wildlife at Pleasant Valley. In this naturalist-guided hike, learn about the sanctuary's resident beavers and how other animals benefit from the ponds that they create. Our route will take us into a mosaic of wetlands built over nearly a century by generations of beavers. As you look for wildlife using these ponds, you'll also learn the story behind the reintroduction of beavers at Pleasant Valley in the 1930's. ADULTS
