Cathleen Stone Island Events

Cathleen Stone Island Events hosts weddings, conferences, team building programs and private celebrations on Thompson Island in Boston Harbor, about one mile from downtown Boston. The island is part of the Boston Harbor Islands National and State Park, and guests reach it by private ferry. It combines the exclusivity of a private resort with the access of an urban conference center, offering outdoor venues with views of the Boston skyline.

Thompson Island covers 204 acres of undeveloped land with mature forests, meadows, freshwater and marine wetlands, salt marshes and notable geological features. A school campus on the island includes dormitories, a dining hall, classrooms, lab space, auditoriums, a gymnasium, outdoor challenge courses and climbing towers. Event sites include the Ocean Bluff Pavilion, Waterfront Landing, Gable Orchard and the Ocean Bluff Gazebo, used for everything from corporate clambakes to family reunions.
