Seven Seas Lagoon

The Seven Seas Lagoon is a man-made lake at the Walt Disney World Resort in Bay Lake, Florida, near Orlando. Located south of the Magic Kingdom theme park, the Seven Seas Lagoon serves as a natural buffer between the Magic Kingdom and its parking lot and connects with the adjacent Bay Lake. The lake reaches a depth of 14 feet. The lagoon is used mainly for recreational boating, as well as by the resort's three Disney Transport ferryboats that transport guests between the Magic Kingdom and the Transportation and Ticket Center.
