About Crowninshield Island

This intimate outcropping features a short loop trail and is ideal for families, who can reach the island by boat or, at low tide, on foot across the shallows.

What makes Crowninshield Island a special place?
We think it’s the humble island’s location within one of the most spectacular coastal settings in the Northeast: Marblehead Harbor. Crowninshield (formerly named Brown’s Island) has served as a comfortable and familiar saltwater playground for generations of locals. It was Louise DuPont Crowninshield, a summer resident for decades on nearby Peach’s Point, who donated the island, which has been a Trustees reservation since 1955.

You can experience the same enjoyment of wading through the shallows, exploring the modest (5-acre) island, and basking in the beautiful locale. Explore saltwater pools full of interesting shells, tidal plants, and creatures. The island features a sandy beach, small open field, and modest woodlands. Migrating birds rest and feed along the shore, while striped bass chase baitfish through the shallows.

A south-facing lawn is especially picnic friendly. Wander along a short loop trail past rocky outcrops that offer wondrous views of the harbor, other small islands, and 17th-century Fort Sewall.

A short footpath leads walkers around the 5-acre island.

When to Visit

Conservation and Stewardship

Management Planning for Our Properties

Since 1891, The Trustees of Reservations have worked to protect special places in Massachusetts and maintain them to the highest standards. To ensure these standards are met, a program of careful planning and sound management is essential. Comprehensive property management plans are created for each reservation and are completely updated approximately every ten years. We often work with volunteers, property users, and members of the community to carry out this planning, which typically involves several steps:

  • Describing in detail the site’s natural, scenic, and historical resources; identifying management issues related to the protection of those resources. 

  • Describing how visitors use the property; outlining the opportunities that the property provides for people to become involved in the work of conservation and caring for their community.

  • Developing a detailed list of management recommendations, a work plan, and a description of financial needs for implementing the actions.

  • Developing a prescribed routine management program for the reservation that will guide staff work plans, volunteer involvement, and the allocation of human and financial resources.
