Dive the Bonnie Castle and/or the wreck of the Islander dive sites.

Bonnie Castle resort offers shore dives immediately off their property with platforms at 30 feet for training with direction lines. Visibility is generally 25 feet and more, often well over 50 feet, and, depending on the season, up to 70 feet.

The Islander was built in Rochester, N.Y., in 1871. This sidewheel steamer measured 125 ft. x 20 ft. x 7 ft. and weighed 118 gross tons. As well as a regular mail carrier between Clayton and Alexandria Bay, the Islander began island and river tours on July 31, 1893. On Sept. 16, 1909, at the dock at Alexandria Bay, the ship caught fire and burnt. Since the tragedy, the Islander has become a favorite dive site for many divers.
