Serenity describes this park that's tucked away in Penobscot Bay where visitors use their own boat, or a private shuttle, to access the island. No phones are available on the island ensuring a Robinson Crusoe-esque experience. Campers choose from one of the 12 campsites or the three Adirondack shelters for accommodations. A trip to Warren Island is guaranteed to create memories that will last all winter long! Folks without their own boat can contact Quicksilver Water Shuttle for boat trips to and from the island.
