The easiest way to visit Boldt Castle!
Tickets are available at out ticket booth beginning at 9 AM and no reservations are needed.
Our shuttle service to Boldt Castle is available every day that Heart Island is open to visitors! The first departure is always as soon as the Castle opens, 10 AM most days (see Boldt Castles schedule below) and every half hour after that first trip.
Approximately 1.5 hrs before they close for the day we can no longer bring passengers TO Heart Island. However the shuttle will continue making trips until ALL visitors have returned to our docks in Alexandria Bay, NY when Boldt Castle closes in the evening.
Once at the castle and after paying your admission, you can spend as much time as you wish on the five-acre island enjoying not only the 129-room castle built by George Boldt for his wife Louise but also its out buildings (Hennery, Power House, and Alster Tower) and its lovely landscaped grounds as well.
