The 5-Hour Boldt Castle Stopover Cruise from Gananoque
Every other cruise on this river shows you Boldt Castle from the water. This is the only one that lets you walk through it. The 5-hour Boldt Castle stopover cruise from Gananoque sails you across to Heart Island, hands you two hours ashore with admission included, then narrates the islands the whole way there and back. It's a full afternoon and it needs a passport — here's everything I tell passengers before they book. You can also see how it stacks up against the other Gananoque boat tours.

Why This Is the Only Cruise That Lands
Boldt Castle is the reason a lot of people come to the 1000 Islands in the first place, and it has a story to match. In the early 1900s, George C. Boldt — the man behind New York's Waldorf-Astoria — set out to build a 120-room, six-storey castle on Heart Island as a gift to his wife, Louise. When she died suddenly in 1904, he wired the crew to stop all work and never came back. The castle stood empty and weathering for 73 years before the Thousand Islands Bridge Authority took it on and began restoring it.
This five-hour cruise is the only one that actually docks at Heart Island, and your two hours ashore are self-guided, so you set the pace through the grand hall, the tunnels, the gardens and the separate Yacht House across the water. Admission is built into the fare. The trade-off is time and paperwork: it's most of a day, and because Heart Island is U.S. soil, everyone aboard needs a passport. If that doesn't suit, the passport-free Ivy Lea two-castle scenic cruise shows you the castle from the water instead.

Important Things to Know Before You Go
This is the trip that rewards preparation the most. From experience:
- A valid passport or NEXUS card is mandatory for everyone aboard — there are no exceptions, and travelers from outside Canada and the U.S. may also need a visa or ESTA
- Outside food and drink are not permitted, so eat before you board or buy from the snack bar
- Two hours ashore sounds long but goes quickly — have a plan before you land
- Wear comfortable shoes; there's a fair amount of walking and stairs on the castle grounds
What to pack
- Passport or NEXUS card — non-negotiable for this cruise
- Comfortable walking shoes for the castle and grounds
- A light jacket for the open river and sunscreen for the water glare
- A card or cash for the Yacht House fee and any snacks
What to leave behind
- Outside food and drinks — they're not allowed aboard
- Any tight afternoon plans; this cruise runs about five hours end to end
Insider Tips for the Boldt Castle Stopover
The advice past visitors wish they'd had before their two hours on Heart Island:
- If you want to see the Yacht House (boathouse), go there first — it's a short shuttle-boat hop away and people run out of time if they leave it to the end
- Start at the top of the castle and work down; the upper floors and the story of the unfinished rooms are the highlight
- Bring the passport even if you 'only might' get off — the crew checks everyone before boarding
- The gardens and the Power House are worth saving 20 minutes for, not just the main house
- Book a morning departure so your castle time isn't rushed by the return schedule
- Buy any food before boarding since outside food isn't allowed and the ashore options are limited
Where It Departs — Downtown Gananoque
Who This Cruise Is For
This is the cruise for people who want more than a view:
- History lovers who want to walk the rooms of Boldt Castle, not just photograph it
- Travelers with passports who have a full afternoon to give the river
- Anyone who'd feel short-changed seeing the castle only from the water
- Couples and small groups happy to explore Heart Island at their own pace
Not ideal for
- Anyone without a passport or NEXUS card — you cannot land at the castle without one
- Families with very young children who won't last a five-hour outing
- Travelers short on time — take a 1 or 3-hour scenic cruise instead
Boldt Castle Stopover Cruise — FAQ
Do I absolutely need a passport?
Yes. Heart Island is U.S. territory, so every passenger on this cruise needs a valid passport or NEXUS card, with no exceptions — travelers from outside Canada and the U.S. may also need a visa or ESTA. If you don't have one, the passport-free Ivy Lea two-castle scenic cruise shows you the castle from the water instead.
How long do I actually get at the castle?
About two hours ashore, self-guided, out of a roughly five-hour total trip. It's enough to see the castle and grounds if you pace yourself — go to the Yacht House first if you want to include it. Compare the timings against the other 1000 Islands cruises from Gananoque.
Is Boldt Castle admission included?
Yes, admission to Boldt Castle is included in the cruise fare. The separate Yacht House across the channel has its own small fee if you'd like to go inside. Everything else on Heart Island is yours to explore during the stopover.
Can I bring my own food?
No — outside food and beverage are not permitted on this cruise. Eat before you board or use the onboard snack bar on the cruise legs. Options on Heart Island itself are limited, so plan ahead.
How much does it cost and when does it run?
It starts around $66 per person including castle admission, and it runs daily from May through the end of October. Live dates and prices are on the booking page. Questions about a specific date? Contact us.
What Passengers Say About This Cruise
The two hours on Heart Island were the highlight of our whole Ontario trip. We went to the boathouse first on the crew's advice — good call, we'd have missed it otherwise. Bring your passport, they check everyone.
Wonderful to actually walk through the castle rather than just sail past. The story of why it was never finished is genuinely moving. Wear comfortable shoes, there are a lot of stairs.
Five hours very well spent. The narrated cruise both ways was interesting and the castle grounds are beautiful. Just remember outside food isn't allowed on the boat, so we ate first.
