1000 Islands Harbor Hotel

The 1000 Islands Harbor Hotel is a AAA Four Diamond hotel set along the St. Lawrence River in Clayton, New York, offering 6,000 square feet of event space across eight distinct venues. From the intimate Picton Boardroom to the riverfront Tent Space, the property accommodates gatherings ranging from small executive meetings to outdoor celebrations of up to 500 guests. The Harbor Ballroom is the hotel's flagship space for large-scale weddings and conferences, welcoming up to 300 guests. Adjacent meeting rooms — including the Calumet and Grindstone Ballrooms and the Murray and Round Rooms — serve conferences, banquets, and private dinners for groups of 50 to 130. Outdoor events benefit from the hotel's landscaped waterfront grounds and a tented riverside setting with the St. Lawrence River as backdrop. Creative catering options, high-speed Wi-Fi, and state-of-the-art audiovisual technology are available across all event spaces. A professional wedding consultant supports ceremony and reception planning throughout the process.
