The Boothbay peninsula is surrounded by beautiful islands, many of which provide significant bird habitat. BRLT protects seven islands in the Boothbay region. BRLT owns a least a portion of six islands and holds an easement on a seventh island. Damariscove, Indiantown and Spectacle Islands have publicly accessible hiking trails. See the Happy Landings guide for detail on accessing these islands by boat. Miles and Lower Mark Islands are owned by BRLT but do not have any hiking trails.

Damariscove Island
Historic Damariscove Island, 5 miles off the Boothbay coastline, offers hiking trails, a small museum and unsurpassed sea views.  BRLT maintains two guest moorings in the harbor on the southern tip of the island, which can be used by daytime visitors or for an overnight stay.  BRLT has a gangway and float for access to the island where two courtesy dinghies are available.  The wooden float is for loading and unloading only.  Boats should not tie up to the wooden float nor to the adjacent stone pier.   These are reserved for fishermen who continue to work out of Damariscove Island, a practice since the early 17th Century.  Visitors are asked to respect their activities.

Indiantown Island
A BRLT guest mooring is located at a wooden pier and float near the northwest tip of the island.  A courtesy dinghy is kept at the float.  Canoes and kayaks may tie up to the float, but small boats should utilize the mooring for extensive visits.  The mooring depth is too shallow for large boats.  Hiking trails are located throughout the island.  BRLT owns the northern half of the 60-acre island and holds a conservation easement on the southern half.  In 1995 and 1996 a major archaeological project sponsored by BRLT was conducted. 

Miles Island
Located in Sheepscot Back River, canoes and kayaks may land near the northwestern corner of the island for day use only.  There are no hiking trails on the uninhabited 17-acre island but visitors may explore it.  Miles Island is surrounded by extensive mud flats which are an important area for migratory seabirds, wading birds, marine worms and shellfish.

Lower Mark Island
The island off of Southport in the Sheepscot River is a 9-acre nationally significant seabird and wading bird nesting site.  The great blue heron rookery is increasing at a time when herons are declining in Maine. 

Spectacle Island
Located in the Sheepscot River, this small island is owned jointly by BRLT and Sheepscot Valley Conservation Association.  The island is popular with picnickers, but boat access facilities are not provided.  Boats anchor off the eastern shore and gain access by dinghy. Canoes and kayaks may land on the sandy beach. The island as easily accessible by canoe from the town landing on McKown Point Road, a distance of 2 miles traveling under the Southport bridge.
