Outing Highlights
Hundreds of Thousands of Tree Swallows at Dusk
At sunset the swallows return from miles away and gather in the river reeds, performing tight, coordinated aerial displays as they come in to roost—an astonishing natural spectacle and the primary purpose of this sail.
A Scenic River Passage
Beyond the roost, the cruise is about the river itself: a quiet sail along the Connecticut River with changing light and riverside landscape that frames the evening’s main event.
Small-Group, Ever-Changing Evenings
Each sailing is unique—small groups, attentive crew, and variable bird behavior mean no two evenings are the same; the captain and crew aim to give passengers a full evening to enjoy the show.

As the sun falls the sky fills with birds returning to the reeds; the crew times the approach so passengers witness the swallows’ aerial ballet.
