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…

The Boat Tour from Clayton to Boldt Castle was a blast! My compliments to Mike with the mike and Captain Jack. The optional self-guided Castle Tour was wonderful! Mike even gave me the mike to tell a couple of pirate jokes. Here's one: What did the pirate say on his 80th birthday? Aye Matey! I'm eighty. LOL

The cruise was very informative and relaxing. We would have preferred a half hour more on Heart Island. Otherwise, we highly recommend this tour.

Great time, the guide was great with his stories of the area. River traffic was heavy in spots with many other craft creating large wakes. Our captain handle those with ease to ensure a smooth and Dry cruise. Next time I would pass on the box lunch....

My son, daughter-in-law and I took the St. Lawrence River Cruise and toured Boldt Castle. We had an amazing time the weather was perfect, just a little chilly out on the water. The young man on the boat provided us with many interesting stories about the various islands and people who owned them. He had grown up in the area, so it was good to be provided with first hand information in many cases. I had been to Boldt Castle 20 years ago, and the renovation continues to be spectacular, albeit SLOW, but all the funds raised by the admission fees goes toward re-building the castle, so I feel my money is being wisely spent. My children enjoyed the trip and the tour very much...a very pleasurable way to spend time with your loved ones.
