Squam Swap is a hidden gem that should be added to your list. The name says it all, it's dense, enclosed, and wet. Keep in mind it can be easy to get a little lost in here so pay attention to the numbered posts leading your way of this 1.75 mile trail. It may not offer the same ocean vistas as some of the others, but the thousands of green ferns and beautiful bogs are a welcome treat not often seen on the island.
