Saint Croix Island, Maine

Saint Croix Island (French: Île Sainte-Croix), long known to locals as Dochet Island (), is a small uninhabited island in Maine near the mouth of the Saint Croix River that forms part of the Canada–United States border separating Maine from New Brunswick. The island is in the heart of the traditional lands of the Passamaquoddy people who, according to oral tradition, used it to store food away from the dangers of mainland animals. The island was the site of an early attempt at French colonization by Pierre Dugua, Sieur de Mons in 1604.

In 1984 it was designated by the United States Congress as Saint Croix Island International Historic Site. There is no public access to the island, but there is a visitor contact station on the U.S. mainland and a display on the Canadian mainland opposite the island. The 6.5 acres (26,000 m2) island measures approximately 200 by 100 yards (183 m × 91 m) and is located approximately 4 miles (6.4 km) upstream from the mouth of the river on Passamaquoddy Bay.

Saint Croix Island, Maine occupies a particular place in the imagination of American public lands. As a Park Unit in Maine, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
