The Wild Center - Tupper Lake
This center is situated in the middle of the Adirondacks and includes many trails, trails, ponds, rivers and exhibits. But the best attraction is the "Wild Walk". This is a series of platforms and walkways - elevated ABOVE the trees so that you can see things differently, from a vantage point you don't usually get to experience. These walkways are loaded with hands-on activities for the kids but there's enough to see and experience is you are visiting without kids. Either way, it is a must see if you are in the area of Tupper Lake!
