Explore the Magnificence of Boldt Castle: A Tour of Heart Island Alexandria Bay, Upstate New York

Boldt Castle is a grand historic mansion situated on Heart Island in Alexandria Bay, New York, in the Thousand Island region. Take a quick look inside Boldt Castle below and with our video above.

Boldt Castle then and now

Construction began in 1900 by George Boldt, a wealthy hotelier, as a symbol of his love for his wife Louise. The castle was intended to be a full-scale replica of a Rhineland castle with ornate gardens, a drawbridge, and a powerhouse.

However, the construction was abruptly stopped in 1904, after Louise Boldt passed away suddenly. Construction never continued, leaving the castle abandoned for more than 70 years.

Boldt Castle has been through several restoration projects over the years to preserve it for future generations. The Thousand Islands Bridge Authority acquired the castle in 1977 and embarked on a multi-million dollar restoration project to restore it to its former glory.

Today, Boldt Castle is open to the public. It is now a museum and event venue. You can even have your wedding at Boldt Castle (Get Wedding Info). Visitors come from all over to see its grand Victorian and Medieval architecture and learn about its fascinating history.

Both guided and self-tours of the castle are available. Visitors are able to explore the grounds, including the Alster Tower, Power House, Dovecotes, and Yacht House.

Getting to Boldt Castle

Boldt Castle is only accessible by water, and visitors can use a tour boat or personal craft to get there.

We used Uncle Sam Boat Tours to get to Boldt Castle. They offer shuttle service and a variety of scenic cruises. Shuttle service is available every day the castle is open. We went with the scenic cruise that also took us down the Thousand Islands to Singer Castle.

You can get tickets for the scenic cruise on their website. As of now, you can only get the shuttle tickets in person. There is another Boat Tour company right next to Uncle Sam and they share the same small parking lot.

Boldt Castle also recommends Clayton Island Tours. They too offer a variety of scenic cruises, one being the Rock Island Lighthouse Tour on a Glass Bottom Boat.

There are also Tour Boat options if you are coming from Canada, Rockport Cruises and Gananoque City Cruises.

The castle and yacht house are not open year round. They open from mid-May to mid-October, and the grounds are open from 10:30 AM to 6:30 PM. If you’re planning a visit, head to their website at BoldtCastle.com for up-to-date information on admission prices and hours. Especially around the Fourth of July and Labor Day.
