Accessible by water taxi, tour boats and private boat, the castle is open for self-guided tours from mid-May through mid-October. The five-acre island is fully handicapped accessible, has complete restroom facilities, extensive docking for private boats, several picnic areas, a gift shop, and a food and beverage concession.
There are six impressive structures to explore on Heart Island the Castle, the Power House, the Alster Tower, the Hennery, the Arch, and a stone Gazebo. Exhibits in the various structures and a 15 minute video presentation offer a look into the lifestyle of George and Louise Boldt, along with a history of the 1000 Islands Region and the restoration efforts on Heart Island.
Inside the Castle the first floor has been restored to reflect George and Louise Boldt’s intended finished interior complete with furnishings.
Hundreds of windows have been replaced and beautiful custom made doors and decorative windows now enhance the entrances. The Castle rises six stories from the foundation level of the indoor pool to the highest towered room.
