I literally made an account to write this review. It's gorgeous and perfect at Umbagog. The sunsets here put all other sunsets to shame. The lake is crystal clear, there are so many great places to snorkel, swim, kayak, fish, literally anything. For a lot of people, the lack of wifi is a deal-breaker, but that's what the Errol library is for. Bring some books, board games, and a sketchpad. (maybe download some tunes) and get ready to relax.
