Warren Island

Warren Island is a wild and serene 70-acre spruce-covered island sitting in Penobscot Bay off Lincolnville, where you anchor off and row or dinghy ashore. Once on land, you'll find 12 campsites and two Adirondack shelters with fresh drinking water, making it a rare Maine island with real overnight infrastructure. A 1.5-mile trail loops the entire island, weaving through the spruce forest with open views across the bay toward the Camden Hills.
