The 1000 Islands Cruise from Gananoque: Choosing Your 1, 3 or 5-Hour Route

Most people arrive in Gananoque knowing they want to get on the water but not how long a cruise should be — and that's exactly why this trip is the easy answer. It's the same boat and the same narrated route; you simply choose where you get off. The one-hour loop threads the tightest, prettiest cluster of islands right off town. The three-hour cruise ranges the whole classic circuit — up the American channel, past Boldt Castle and Millionaire's Row, under the 1000 Islands International Bridge, and back down the Canadian side. The five-hour version does all of that and lands you on Heart Island for two hours to walk through Boldt Castle itself.

At 4.5 stars across nearly 4,700 reviews, it's the most-booked cruise on the river for a reason: it fits a family with restless kids and a couple who want the whole afternoon equally well. If you already know you want to set foot in the castle, jump to my write-up of the 5-hour Boldt Castle stopover cruise; if you're tight on time, the 1-hour heart-of-the-islands cruise is the quick taste.

The route is built to pack the river's greatest hits into whatever window you pick. Over the cruise you'll:

• Cruise the most concentrated stretch of the 1000 Islands, up the U.S. shore and down the Canadian side
• Pass Boldt Castle on Heart Island and, on the long route, step ashore to explore it
• Glide by Millionaire's Row, where old-money families built island cottages in the late 1800s
• Watch ocean-going freighters work through the St. Lawrence Seaway shipping channel
• Cruise under the arc of the 1000 Islands International Bridge
• Hear the history and legends of the river over live onboard commentary

What's Included

• Your narrated cruise on a triple-decker vessel with open and enclosed decks
• Live audio commentary on the islands, castles and Seaway
• On the 5-hour route: Boldt Castle admission and a two-hour stopover
• Onboard restrooms and access to a snack bar and coffee shop

Not Included

• Food and drinks beyond what you buy at the onboard snack bar
• Gratuities for the crew, which are optional but appreciated
• Parking in town and any meals ashore before or after

A little planning makes the day smoother. Here's what I tell people at the dock:

• Only the 5-hour route lands at Boldt Castle, and that landing is on U.S. soil — every passenger needs a valid passport or NEXUS card, no exceptions
• It's always cooler and windier out on the open river than in town, even on a hot day
• The commentary sounds clearer on the enclosed decks than up top in the wind
• Arrive 30 minutes before departure — the town dock and parking get busy on summer weekends

What to pack

• A light jacket or windbreaker for the open deck
• Sunglasses, a hat and sunscreen for the glare off the water
• Binoculars and a camera for the castles and passing freighters
• A passport or NEXUS card if you're taking the 5-hour castle route

What to leave behind

• Big bags — deck space is for people, not luggage
• Any tight afternoon plans if you've booked the five-hour route, which runs most of the day

Things regulars and past passengers have learned that the booking page won't tell you:

• On the 5-hour castle stop you need every one of those two hours — if you want to see the boathouse (Yacht House), go there first or you'll run out of time
• Sit on an enclosed deck if hearing the commentary matters to you; the open top deck is scenic but the wind swallows the narration
• If you plan to eat in Gananoque right after, be one of the first off the boat or the restaurant wait can be long
• The best scenery is the middle stretch the Gananoque boats focus on — that's where the islands are most varied and concentrated
• Book a morning departure for the calmest water and the best light on the castles
• Even on the shorter routes, grab a spot on the side facing the islands as you head upriver

The flexible 1/3/5-hour format makes this the most adaptable cruise on the river:

• First-timers who aren't sure how long they want to be on the water
• Families who can pick a short loop for young kids or a full day for older ones
• Travelers who want the option to actually walk through Boldt Castle
• Anyone building a day trip from Kingston or Brockville into their Ontario route

Not ideal for

• Travelers without a passport who specifically want the castle landing — take a scenic route instead
• Anyone hoping for a sunset cruise; these are daytime narrated sailings
• Visitors who want a private or small-boat experience rather than a large tour vessel
