Navigate your way to this intimate outcropping that’s reachable by boat, or, at low tide, on foot across the shallows, and amble along a short loop trail to a wooded hilltop.

Explore a sandy beach, a small open field, and a wooded hilltop on this coastal island in picturesque Marblehead Harbor. Formerly called Brown’s Island, the property’s name honors Louise DuPont Crowninshield, a pioneer in America’s historic preservation movement from 1925 until her death in 1958. She summered at Marblehead’s Peach Point on nearby Dolliber Cove.

Accessible by foot at low tide, this five-acre island packs an abundance of family-friendly experiences. If walking across the dry channel at low tide, arrive one hour before dead low tide and leave one hour after to allow for maximum time on the island.

Peek into tidal pools full of interesting shells and creatures, and wander along a short loop trail past rocky outcrops offering wondrous views of the harbor, other small islands, and 17th-century Fort Sewall. A south-facing lawn is a go-to spot for a mid-day picnic.
