Boldt Castle and Yacht House, Alexandria Bay

(4.7/5 based on 1,300+ reviews on the web)
Nestled on an island of the St. Lawrence River, Boldt Castle and Yacht House tells a tragic story of a wealthy couple who never got to live in their lavish estate. Straddling the border between the United States and Canada, the castle came to life in 1900, constructed by millionaire George C. Boldt (owner of the famed Waldorf Astoria Hotel in New York City). It was cancelled in 1904 due to the sudden death of his wife, but construction eventually resumed in 1977. Today you can see some incomplete and some finished rooms, a basement with a swimming pool and bowling lanes, hallways with pictures and artifacts, and a collection of wooden boats. Learn about how electricity was obtained in the early 20th century. Take a guided tour and explore the surrounding grounds.

  • We've been to Bolt many times. We are always impressed by the size, the workmanship and the history. This is a good trip for any one, but kids really love it!

  • It was about two decades ago that I last visited this place. At the time it was a large abandoned castle on an island. Today it's in the process of being restored and can truly be considered an attraction worth visiting. There still remains some work to do and perhaps they can eventually build a nice table-service restaurant inside of it rather than just the junk food that's available at the entrance. The landscaping is beautiful and the boat ride to and from on the Thousands Island is even better!
  • LOVED the self guided tour. We had been here before and just wandered around, but this time spent the extra $$ to get the mp3 player and hear the history. Some of the signs were a little hard to follow I could swear one of the directions was turn left after exiting the house, but we couldn't find the # we were looking for!) It was a VERY hot day, and they had plenty of fans on for circulation. Staff are friendly and helpful, and the grounds are magnificent. The history/story of this place is amazing.
  • It was good to visit. The upper floors aren't done so not a whole lot to see. The outside area is pretty. The food vendors are decent for fast food. CANADIANS: when u get on the dock do NOT pass the yellow line on the dock. It's a $5k fine and boat gets taken away. Stay and wait for guard.
  • So lovely, they are really doing an amazing job of restoring the place. You are able to go around and explore your self. Well worth spending the day there, the landscape is beautifully and there are lovely picnic area around the island.
  • It's really improved since the last time I was there 10 years ago. Much more to see and it's nice to see their not only just keeping it up but restoring to what was formally there. It's a great piece of history that you should visit. While it's a sad story that lead to the castle being ultimately abandoned, we see a part of our past being restored so we can visit. Both gift shops are kinda bare so don't expect to walk off the island with more than a bunch of pictures and a couple of trinkets.
