On the lake
A narrated cruise leaves from Sunapee Harbor on a fixed schedule. Rentals and private launches allow a self-directed route, but require current weather, parking, inspection, and posted-restriction checks.

Things to Do in Sunapee
A warm-weather day can move from boat or beach to the harbor; colder months trade the water for Mount Sunapee snow, winter roads, and shorter village stops.
Choose by place and season
Lake Sunapee, the harbor, and Mount Sunapee offer distinct outings
Around the harbor

South in Newbury
Mt. Sunapee State Park combines the public beach, picnic grounds, launch, campground, and marked hiking access. The adjoining resort adds lift-served skiing when terrain is open.
