Otter Brook Preserve, Harpswell


  • Preserve Size: 68 acres
  • Trail Mileage: 1.6 miles in system
  • Pets: yes
  • Difficulty: easy
  • Sights: Otter Brook, freshwater marsh

This preserve has two loops making up a 1.6-mile trail system. It appears to me, based on an untrained eye, that the forest here is successional, that is, it’s recovering from harvesting. The trail meanders along Otter Brook for a ways, which is one of the largest freshwater streams in Harpswell. The freshwater stream, marsh, and pond system is rare in the area, according to the Harpswell Heritage Land Trust, and it was important to preserve it to help keep Ewing Narrows and Harpswell Cove clean for healthy clams and other marine life. Along the trail, you’ll see glimpses of the brook, and there is a viewing spot by the marsh with a bench.

Directions: The parking area is at 429 Harpswell Neck Road. From the intersection of Rt 123 and Bath Road at Bowdoin College in Brunswick, follow Rt 123 south for 6.1 miles. Look for a parking lot on the left.


Let me know if you have any trail updates or corrections!
