History and Cultural Heritage

Isle au Haut has a long and diverse history. Native American tribes, including the Penobscot people, were the island’s earliest inhabitants, relying on its natural resources for fishing and gathering. In the 17th century, European explorers, most notably French navigator Samuel de Champlain, arrived and named the island "Isle au Haut," which translates to "high island" in reference to its rugged, elevated terrain.

In the 19th and early 20th centuries, the island was primarily a fishing and farming community. During this time, it attracted summer visitors, including artists, writers, and wealthy families, many of whom built summer cottages and established a seasonal community that still exists today. In 1943, the U.S. government purchased the southern portion of the island to be included in Acadia National Park, thus preserving its natural beauty and preventing overdevelopment.

Isle au Haut Today

Today, Isle au Haut remains sparsely populated, with a permanent population of fewer than 100 residents. The island comes alive in the summer, however, when seasonal residents and tourists flock to its shores. There are no hotels or resorts on the island; instead, visitors can stay in rental homes or camp at Duck Harbor, one of the most remote and scenic campgrounds in Acadia National Park.

Access to the island is limited, as there is no bridge or causeway connecting it to the mainland. The Isle au Haut Ferry, departing from Stonington, Maine, provides daily service to the island during the summer months and a more limited schedule in the off-season. Visitors must carefully plan their trips, as the ferry ride takes about 45 minutes, and the island's limited amenities require a self-sufficient mindset.

Acadia National Park on Isle au Haut

The portion of Isle au Haut managed by Acadia National Park offers some of the most remote and scenic hiking trails in the park. Unlike the bustling areas of Acadia on Mount Desert Island, Isle au Haut’s parkland sees far fewer visitors, providing a more serene experience.

The Duck Harbor Mountain Trail is one of the most popular hikes on the island, offering a moderate climb through forests of spruce and fir to the rocky summit of Mount Champlain. The views from the top are unparalleled, with sweeping vistas of the Atlantic Ocean and the surrounding islands. The trail also passes through coastal meadows and granite outcrops, showcasing the island’s diverse landscape.

Another popular hike is the Western Head Trail, which skirts the island’s southern coastline, offering stunning views of the ocean and rugged cliffs. The trail winds through dense woods and along rocky shorelines, leading to picturesque beaches and secluded coves.

For those seeking a longer adventure, the Isle au Haut Loop offers an opportunity to explore much of the parkland in a single day. This 7-mile loop traverses the island’s varied terrain, from coastal cliffs to tranquil forests, providing hikers with a comprehensive view of Isle au Haut’s beauty.

Wildlife and Nature

Isle au Haut’s isolation and protected status have made it a sanctuary for wildlife. The island is home to a variety of bird species, including bald eagles, osprey, and peregrine falcons. Its coastal habitats provide excellent opportunities for birdwatching, especially during migratory seasons. Along the shoreline, visitors can often spot harbor seals lounging on rocks or playing in the surf.

The island’s forests are primarily composed of spruce, fir, and pine, creating a habitat for deer, foxes, and other small mammals. The abundance of tidal pools along the rocky shores also supports a vibrant marine ecosystem, teeming with crabs, sea stars, and other creatures.

Duck Harbor Campground

For those looking to spend a night on the island, Duck Harbor Campground is the ideal destination. This primitive campground is located in a remote part of the island and offers five lean-to shelters, each with spectacular views of the ocean. The campground is open from mid-May through mid-October and requires reservations, which can be made through Acadia National Park’s website. With no electricity or potable water, campers must come prepared for a rustic experience, bringing their own supplies and being mindful of Leave No Trace principles.

Camping at Duck Harbor is an experience unlike any other in Acadia National Park, offering unparalleled stargazing, the soothing sound of waves crashing on the shore, and complete immersion in the island’s natural beauty.

Planning a Visit to Isle au Haut

Visiting Isle au Haut requires careful planning. Due to the island’s limited services and accommodations, day trips are common, but those looking to explore its trails more thoroughly or camp at Duck Harbor should plan ahead, especially in the busy summer months.

There are no stores or restaurants on the island, so visitors must bring all necessary supplies, including food, water, and camping gear. The ferry service from Stonington operates seasonally, with tickets often selling out quickly, especially in the summer. Visitors should also be aware that cell phone service is spotty at best, adding to the sense of remoteness that makes Isle au Haut so appealing.
