Serenity describes this park that’s tucked away in Penobscot Bay where visitors use their own boat to access the island. The park is designed for the boating public, and there is no public ferry transportation to the island. No phones are available on the island ensuring a Robinson Crusoe-esque experience. Campers choose from one of the 10 campsites or the two Adirondack shelters for accommodations. A trip to Warren Island is guaranteed to create memories that will last all winter long!
