Go for the treehouse. The Center, which is housed in a gorgeous old lodge on a bluff over looking Cayuga Lake, has a lot of old world charm with it's big windows and stone fireplace. Built as a Preventorium for children during the Tuberculosis era, it is now an educational center for learning about local wildlife and native plant and tree species. With miles of trails to walk, gorges to explore, and a permanent collection of animals to visit, you can spend an entire afternoon here soaking up the atmosphere. For many, the big draw is the 6 story treehouse. Built in the woods in a creek bed, as you climb you become a voyeur in the active world in the treetops, spying on the birds and squirrels as they go about their business.
