Overview

This 5-hour cruise departs from Gananoque, Ontario, and travels through the American section of the 1000 Islands region on the St. Lawrence River. The boat passes several landmarks including Zavikon Island, known for its 32-foot international bridge connecting a Canadian and an American island, Millionaire’s Row, the St. Lawrence Seaway, and the 1000 Islands International Bridge that links northern New York with southeastern Ontario. The cruise includes audio commentary in English and French and has onboard restrooms. After approximately three hours of cruising, there is a two-hour stopover at Boldt Castle on Heart Island. During this stop, passengers can tour Boldt Castle and the adjacent Boldt Yacht House. Boldt Castle was built starting in 1900 by hotel magnate George C. Boldt as a summer home for his wife Louise, but construction stopped after her sudden death, leaving the castle unfinished for over seventy years. Admission to Boldt Castle is included in the price. Outside food and drinks are not allowed on board. A valid passport is required to board the cruise, and visitors from outside Canada or the U.S. must have a visitor’s visa and an approved Electronic System for Travel Authorization (ESTA). The operator may cancel the cruise in case of severe weather or unsafe water conditions.

Itinerary

1

Thousand Islands Bridge

The Thousand Islands International Bridge is a system of bridges maintained by the United States that crosses the Saint Lawrence River, connecting northern New York with southeastern Ontario. Built originally in 1937 and expanded in 1959, it spans the Canada–US border within the Thousand Islands region.

2

Boldt Castle and the Boldt Yacht House

Construction of Boldt Castle began in 1900, commissioned by millionaire George C. Boldt as a tribute to his wife Louise and designed as their summer home on the St. Lawrence River in the heart of the 1000 Islands. The castle was intended to rival those of Europe. However, Mrs. Boldt died suddenly months before completion, and Mr. Boldt halted all construction on Heart Island, leaving the property vacant for over seventy years.

3

1000 Islands Tower

The 1000 Islands Tower is a concrete observation tower on Hill Island near the U.S.-Canada border, located in Ontario. Built in 1965, it rises 400 feet (120 meters) above the St. Lawrence River and provides panoramic views of the Thousand Islands in both countries.

4

Zavikon Island

Zavikon Island features a 32-foot-long bridge that connects a Canadian island with an American island, considered the shortest international bridge in the world. According to the Canada-US boundary agreement, no single island is divided between the two countries. Approximately two-thirds of the Thousand Islands belong to Canada, with the remaining third in the United States.
