Thompson Island Open House

Join Outward Bound for a special Open House on Thompson Island, celebrating the Boston Harbor Islands’ 25th anniversary as a National Park and 50th anniversary as a State Park.

This year, we celebrate the 25th Anniversary of the Boston Harbor Islands as a National Park and 50th Anniversary as a State Park.

Thompson Island is a proud founding member of the Park and is helping to celebrate this milestone with an Open House. On Sunday, October 2nd, all areas of the island will be open and available for guests to explore.

The ferry will depart the EDIC Berth 10 dock at the Seaport at 12 noon. Please arrive at least 15 minutes prior to departure. The ferry ride takes 30 minutes.

This is a rain or shine event. Please note that some guests must be outside for the duration of the ferry ride.

Once on the island, there will be tours led by National Park Service naturalists, campus tours, history discussions, and light refreshments. Most of all it is a day to walk and explore.

The ferry will depart the island promptly at 3:30 pm. Once again, please arrive early for the departure.

There is no cost to visit the island. There is a $5.00 ticketing fee for those attendees 3 and older. Everyone must have a ticket; please buy a free ticket for anyone under 3.

*All adult ticket-holders must provide proof of being fully vaccinated (age 12 and up), and show an ID or proof of residence to board the UPA Ferry. Ticket holders 18 and up will also need to complete an app-based COVID symptom and contact screening process (Clear to Go). A responsible adult must complete Clear to Go for any accompanying minors in their party.
