Quests

Thames River Heritage Park quests are self-guided, family-friendly, treasure-seeking hikes that take you on a fun learning adventure. Your mission, should you choose to accept it, is to follow a series of clues at Fort Trumbull State Park, Waterfront Park in Downtown New London, Fort Griswold Battlefield State Park or Thames Street in Groton to learn about its history and ecology while solving a word puzzle. 

‘Questers’ who finish a TRHP Quest anytime during the year and send a selfie from the final location to [email protected] will be entered into a random weekly prize drawing for a Hop-On, Hop-Off Harbor Cruise ticket. Finish all 4 TRHP Quest and send 4 photos from each location to increase your chances of winning!
