White Island Preserve

Harpswell Heritage Land Trust

The mudflats off the southern portion of White Island in Middle Bay provide excellent habitat for shore, land, and wading birds.

Bald eagles and osprey have been sighted nearby, and it is a popular stopover for migrating birds and waterfowl during their spring and annual migrations. Explore the extensive mudflats at low tide, or take in the wooded shoreline from your boat or kayak. White Island is a great place to see diverse species of birds, particularly during the migration in spring and fall.


Access by water only. The steep shore can make landing difficult.
