Bowdoin Coastal Studies Center, Orr’s Island

  • Pets: yes

Walk the perimeter of this college-owned land at different times of the day and in different seasons to experience the changing light on the sea. But don’t ignore the center trail in the long peninsula. This red-blazed trail takes you to a bit higher ground, where you have some good views.

This is a remarkable piece of land, owned by Bowdoin College, which maintains a marine lab, large meadow and farmhouse on site (the property is also known as Thalheimer Farm). The network is about 3.6 miles. Dogs must be leashed.

Directions: From the intersection of Mountain Road and Harpswell Islands Road (Rt. 24), follow Harpswell Islands Road south toward Orr’s Island. Approximately 2 miles after crossing onto Orr’s Island from Great Island take a left onto Bayview Road (this turn is easy to miss). The dirt road into the center extends off the end of Bayview.
