Clamtown is a quaint village surrounded by rolling, forested mountains. There is a small creek running directly through the village that feeds into the Little Schuylkill River. The village also has a small lake commonly known as the "Little Schuylkill Lake" that is just outside of it. Some fish such as trout can be found here. The lake itself is presumed to be man made due to the abandoned train depot directly next to it.
