St. Croix Island International Historic Site preserves the location of a 1604 French settlement on the St. Croix River, offering visitors a unique glimpse into North America’s early colonial history and the natural beauty of a remote river island.
St. Croix Island International Historic Site is situated on a small rocky island in the St. Croix River, which forms part of the international border between Maine, USA, and New Brunswick, Canada. The site commemorates the first French attempt to establish a permanent settlement in North America in 1604, led by Pierre Dugua, Sieur de Mons, and Samuel de Champlain. The early settlers faced harsh winters, leading to significant hardship and death. Today, the island is preserved to interpret this pivotal moment in early colonial history and Franco-American relations. The surrounding ecosystem features a mix of boreal forest species and riverine habitat supporting diverse birdlife and aquatic species. While visitors cannot access the island itself due to preservation and safety concerns, the nearby mainland interpretive area offers exhibits, trails, and river overlooks. Activities in the vicinity include birdwatching, interpretation of historical exhibits, and enjoying scenic views of the St. Croix River valley. The site’s remote, tranquil setting offers a quiet retreat for history enthusiasts and nature lovers alike. Its river environment and status as an international historic site enhance its significance both culturally and environmentally. Interpretive programs and ranger-led tours provide context for the island’s legacy within early European colonization of North America.
