A Sanctuary That Means It
Holbrook Island Sanctuary covers 1,345 acres on the western shore of Penobscot Bay in Brooksville, on the Blue Hill Peninsula. The park protects a diverse mix of coastal habitats: salt marshes, cobble beaches, freshwater ponds, hardwood forests, and a 115-acre island accessible by kayak at certain tides. This is one of the quieter state parks in Maine, and the no-dogs policy contributes to an atmosphere that feels genuinely wild.
The sanctuary owes its existence to Anita Harris, who purchased the land over several decades and donated it to the state in 1971 with the stipulation that it remain “in its natural wild state.” That mandate has been taken seriously. There are no campgrounds, no concession stands, no playground equipment. There are 11 miles of trails, a gravel beach, picnic tables, and silence.
Trails
The trail system covers 11 miles through varied terrain, from coastal shoreline to the summit of Backwoods Mountain (the highest point in the sanctuary at about 350 feet). The trails connect to create loops of different lengths, so you can tailor your hike to the time you have.
Backwoods Mountain Trail climbs to the summit through mixed forest and offers views of Penobscot Bay and the surrounding islands from an open ledge at the top. The round trip is about 2 miles with moderate elevation gain.
Goose Falls Trail follows the shore to a reversing falls where tidal water flows through a narrow channel. The falls reverse direction with the tide, which is fascinating to watch. The trail is about 1.5 miles round trip and mostly flat.
Fresh Pond Trail circles a small freshwater pond in the interior of the sanctuary. The 1-mile loop is easy walking through forest and along the pond shore. Beavers are active here, and you may see lodges and dams.
Backshore Trail runs along the Penobscot Bay shoreline with views of the islands and the Camden Hills across the water. The cobble beach along this section is good for beachcombing and tide pooling.
Goose Falls is a reversing falls, meaning the water flows in different directions depending on the tide. Visit during a strong incoming or outgoing tide for the most dramatic water movement. Check the tide chart for Brooksville before your hike.
Kayaking
The sanctuary’s shoreline is excellent for kayaking. You can launch from several points, including the beach at Indian Bar Road and the head of Tom Cod Cove. From the water, you can paddle to Holbrook Island itself (115 acres, accessible depending on tide and conditions) or explore the coves and inlets along the bay.
The waters around the sanctuary are relatively sheltered compared to the open ocean, but tidal currents can be strong in the narrows. Check conditions before launching and stay aware of the tide. Cold water gear is recommended for spring and fall paddling.
Dogs are not permitted anywhere in Holbrook Island Sanctuary. This is a strict policy intended to protect wildlife habitat. Leave your dog at home or make other arrangements before visiting.

Brooksville, Blue Hill, and the surrounding towns have excellent restaurants, art galleries, and a thriving local food scene. The Brooklin General Store and the Blue Hill Food Co-op are good stops for picnic supplies.
