Loon Lodge

Located on beautiful Damariscotta Lake, "Loon Lodge" is a rustic cabin from another era. Fall asleep to the sound of crickets and frogs and wake every morning to the call of the lake's many loons. The cabin is 30 minutes from Augusta and 15 minutes from Damariscotta. Hiking enthusiasts will enjoy climbing the Camden Hills-a quick 45 minute drive from the lake. You’ll love my place because of the views, the ambiance, the people, and the location. My place is good for couples and solo adventurers.
