Thousand Islands Bridge
The Thousand Islands International Bridge (French: Pont des Mille-îles) is an American-maintained international bridge system over the Saint Lawrence River connecting northern New York in the United States with southeastern Ontario in Canada. Constructed in 1937, with additions in 1959, the bridges span the Canada–US border in the middle of the Thousand Islands region.
Boldt Castle and the Boldt Yacht House
Construction began on Boldt Castle in 1900 at the bidding of millionaire hotel magnate George C. Boldt as a tribute to his beloved wife Louise. Boldt Castle was designed as their summer dream home. A castle rivaling those of Europe, built on the St. Lawrence River, in the heart of the 1000 Islands. However it was not to be, Mrs. Boldt passed away suddenly just months before the completion of the castle. Mr. Boldt was inconsolable and immediately stopped all construction on Heart Island, leaving the property vacant for over seventy years.

Good trip except the bad weather. The castle still in reconstruction to second floor. If the boat is full, maybe not enough time for visiting the island

In the cruise and in Boldt Castle with my family everything are memorable. But disappointed because the city cruises never give us the one ticket from Boldt Castle that not used. Because one never join us because the she called for work. Why the city cruises never give the ticket? We paid that ticket! I hope you can do action of this. Thank you

This was a really lovely tour. Booking this tour couldn't have been easier. You get your tickets sent to your phone and the instructions on where to go are very clear. I will book with Viator again!!

Boldt Castel and the grounds are simply spectacular! The cruise was informative and interesting! Gananoque is a lovely place to visit for an inexpensive weekend getaway. It is a very quaint town with friendly service. Looking forward to going back!!!
