Thames River Heritage Park is elated to announce the return of Historic Boat Tours, Evening Cruises and the Hop On, Hop Off Harbor Cruise on the river starting on Saturday, June 13. Each weekend, there will be over six excursions to choose from between Friday and Sunday. All ages are welcome to discover the Park along the Thames River! 

The Park operates all tours and experiences across four departure locations: Fort Trumbull State Park and City Pier in New London and Nautilus Dock and Thames River Landing in Groton. This gives folks on both sides of the river the opportunity to get out and explore! Full Moon, Fireworks and Drone Cruises for “Celebrate New London” and other major local events will be rolled out as the season progresses. 

This year, in honor of the Park’s 10-year anniversary, youth ages 4-17 ride for $5 when an adult ticket is purchased by a parent or guardian. This only applies to Historic Boat Tours and the Hop On, Hop Off Harbor Cruise. All Boat Tour tickets must be purchased online, and infants ages 0-3 always ride free! 

The Hop On, Hop Off Harbor Cruise will see the addition of a fourth stop at the Nautilus Dock on Sundays only! Saturday’s traditional schedule will have three departure locations between New London and Groton. Locally known as the Water Taxi, the one-hour loop connects the park’s heritage sites along the Thames River.  

This service will operate on both Saturday and Sunday between 11am-5pm and walk-ons are welcome to pay as they board the boats. Hop on at one location and off at another to experience heritage sites, state parks, shopping or restaurants. Guests are also welcome to sit back and relax for the one-hour loop. 

Well-behaved dogs and coolers are even allowed! We also offer individual Season Passes for the entire summer. This will become your go-to activity with your visiting guests and family!
