The Schoodic Peninsula is a peninsula in Down East Maine. It is located four miles (6 km) east of Bar Harbor, Maine, as the crow flies. The Schoodic Peninsula contains 2,266 acres (9 km), or approximately 5% of Acadia National Park. It includes the towns of Gouldsboro and Winter Harbor. The peninsula has a rocky granite shoreline containing many volcanic dikes. The peninsula is home to the former United States Navy base, NGSA Winter Harbor, which has been converted into a National Park Service training center. A 3,300-acre (13 km2) resort development has been proposed for land abutting Schoodic Peninsula's national park holdings to the north.
