A day spent on the sandy "beach" at Echo Bay is like having your own little piece of paradise. Far on the north shore of Lake Placid's Echo Bay, slightly to the left of center, you'll find a beautiful little sandy spot.
Great swimming and it's easy to pull boats up with no rocks anywhere nearby. It's not really a beach, but the shore is very shallow and user-friendly. Get there early as it's tiny and a popular spot!
