Connecticut Trails Day on June 5 is being celebrated with complimentary harbor cruise tickets for the Thames River Heritage Park water taxi as well as special activities to help learn about the region’s history and ecology.

In the Thames River Quests, co-sponsored by the Connecticut Sea Grant program and the heritage park, participants follow a set of clues at different locations to solve a word puzzle. The quests take place at Fort Trumbull State Park and the downtown Waterfront Park in New London; and at Fort Griswold Battlefield State Park and Thames Street in Groton.

Those who register and complete the quests on Trails Day can receive a free harbor cruise ticket and will be eligible to enter a drawing for heritage park T-shirts. The tickets can be used when the water taxi begins operating June 12.

Participants are asked to pre-register on the heritage park website. To download and print the direction visit thameriverheritagepark.org/quests.

“These Quests are a wonderful way to get outside and visit places perhaps you haven’t before, while learning about the rich maritime heritage and history of the Thames River region,” said Nancy Balcom, associate director of Connecticut Sea Grant.

At the end of each Quest, participants are asked to take a photo and post it to their Facebook or Instagram account with @ThamesRiverHeritagePark #TRHPQuest or email it to: info@thamesriverheritagepark.org to receive a complimentary ticket and to be entered into the prize drawing. Winners will be randomly selected throughout the summer.

The Thames River Quests are co-sponsored by The Day.
