Thames River Heritage Park is a Connecticut heritage park connecting more than thirty historic and cultural sites along the Thames River, including the Submarine Force Museum and Fort Griswold Battlefield State Park. A seasonal water taxi, run on refurbished navy vessels, makes a continuous hop-on hop-off loop between landings in New London and Groton, and the park also offers narrated cruises, walking tours and audio tours. The nonprofit Thames River Heritage Park Foundation operates and promotes the park.
General tours guidance
Habits that pay off across this whole category, not rules for this one venue. Always check the official site for the specifics.
Confirm the meeting point
It is often a corner, a lobby, or a dock rather than the address you searched for. Check it the night before.
Small groups fill first
In high season the intimate departures sell out well before the big-bus options do.
Ask how much is on foot
Knowing how much of the route is walking, standing, or outdoors tells you what to wear and carry.
Read the weather policy
Cancellation windows and rain rules vary by operator, and they are easier to find before you pay than after.
