Thousand Islands Private Yacht Charter & Castle Tour

Glide through the legendary Thousand Islands archipelago aboard a private chartered yacht, weaving between 1,864 emerald islands and stopping at the fairytale Boldt Castle — one of North America's most romantic landmarks.

What to expect

Your captain navigates the narrow channels between pine-clad islands, sharing the legend of George Boldt's unfinished love letter in stone. You'll dock at Heart Island and explore Boldt Castle's turrets and boathouse at leisure. Back on the water, watch osprey dive and scan for great blue herons along the shoreline. Sunset on the return sail, with the St. Lawrence glowing amber, is the definition of bucket-list.

Good to know

Pre-book the charter at least 4–6 weeks ahead; castle entry is paid separately on arrival. Allow a full day — departure from Kingston or Gananoque. Confirm your all-aboard time and plan to be back at the ship with at least 90 minutes to spare.
