Visit Thompson Island!

Open House- October 2, 2022

2022 marks the 25th anniversary of the Boston Harbor Islands National 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 2022 all areas of the island will be open and available for guests to explore.

The ferry will depart the EDIC Berth 10 dock in the Seaport at 12 noon. Please arrive at least 15 minutes early. 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 3:30pm. 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.
