The cruise is gentle but engaging, perfect for those seeking a serene yet dynamic outdoor adventure. During the sail, visitors can enjoy unobstructed views of the river’s winding course, rippling waters, and the colorful horizon at sunset.

Whether you're an avid birdwatcher or simply looking to enjoy an evening on the water, the Onrust Sunset Sail offers a meaningful, photo-worthy experience that highlights the vibrant biodiversity and rich history of the Connecticut River.
Route Schematic
Route & Key Stops
The sail follows a short river route: departure from the museum, time underway for riverside viewing, arrival at the swallow roost for sunset, then return to the dock.
Connecticut River Museum / Onrust Boarding
Board Onrust at the museum dock and prepare for the evening departure; crew briefings and embarkation happen here before the sail begins.
Scenic Passage Along the Connecticut River
Sail upriver or downriver (as conditions dictate), watching shoreline scenery and enjoying the unfolding light as the boat approaches the swallow roosting area.
Swallow Roost at Sunset
The vessel moves into position at the special roosting location in time to watch hundreds of thousands of Tree Swallows descend into the reeds and settle for the night.
Return to Dock
After the birds have settled, the sail returns to the museum dock; exact return time can vary slightly with tides and bird behavior.
The cruise typically lasts about two hours but may be extended or shortened by up to roughly 15 minutes depending on tides and the behavior of the birds; passengers should be able to board and move about a small sailboat and follow crew safety briefings.
