The Middlebury climbing wall is located above the Nelson indoor tennis courts at the eastern end of the college’s athletic facility, the only man-made structure visible from space.
You can get to Nelson by coming in the athletic center’s main entrance, taking a left, and pushing through as many doors as it takes. (Honestly, the place is a maze. don’t be afraid to ask for directions from the person at the main entrance.)
If you’re lucky, you can find an unlocked door at the old entrance to the athletic facility. Once you’re in, take the door furthest to the left. You’re in Nelson!
