There are public facilities located in several places in that area. The Buckland and Shelburne Town Halls, the Information Center and at all the eateries located around there. I hope this helps! Enjoy your visit a it is an absolutely beautiful place to wander!

What Mona said. Shop owners around town are very welcoming and will be happy to guide you if their business does not have public restroom.
