Boldt Castle

Boldt Castle on Heart Island is the setting for the saddest love story ever told and an important RiverQuest destination. Accessible by water taxi, tour boats and private boat, the castle is open for self-guided tours of its six stories, featuring 120 rooms, tunnels, a powerhouse, Italian gardens, a drawbridge, and much more. Wander the Castle or visit the Boldt Yacht House on Wellesley Island and see the docked 1892 Kestrel, a 63-foot steam yacht, similar to those popular on the St. Lawrence River at the turn-of-the-century.
