Holbrook Island Sanctuary
The 1,230-acre Holbrook Island Sanctuary protects the region’s fragile ecosystem and has nine hiking trails (pick up trail maps in the parking lot), a gravel beach with splendid views, and a picnic area. There's a good chance you'll spot a blue heron, osprey, or bald eagle here. Note that the sanctuary, which is open from 9 am till sunset, is on the mainland; Holbrook Island itself is privately owned.
