Boldt Castle and Yacht House, Alexandria Bay

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.

  • It’s amazing. Cool breeze & calm place. But The castle is unbelievable , the inside interior was awesome and the island 🌴 is very very beautiful. Perfect summer vacation. In summer bit crowded. My kids love the island. So many small island are there . We roam around 2 hours and very good service of uncle sam’s boat tour. Really good place. Recommended.
  • Boldt Castle is a tour organised by operators of 1000 Islands tour. It is a medium sized castle. The income generated by way of tourism, we understand, is wholly utilised for preserving the castle. The operators allow about 2 hours for look around which is sufficient to cover the length and breadth of the castle. Public restrooms are available and the entrances are wheelchair accessible. A couple of restaurants are doing business on the island
  • Really cool experience in what feels like a life-sized doll house since it was never actually lived in. Definitely take the tour and watch the video to get the special history. Restoration was still in-progress at the time of my visit (late summer 2016), but the skill and attention to detail appropriate to the era when it was originally built is impressive.
  • It was a beautiful day. You travel here by tour boat. The captain tells you details about thousand islands. Not great food on board. You get to the castle where you can do a self tour or a guided one. You can also walk the grounds which are beautiful. Nice gift shop.
  • The history of this iconic castle catches your interest immediately. My family and I could have stayed all day and we still wouldn't have absorbed it all. Definitely a place we plan to return to.
