Thousand Islands & Kingston getaway
Gananoque: 1000 Islands Cruise & Optional Boldt Castle Entry
A scenic river escape, not another lake trip
The Thousand Islands region — the St. Lawrence River’s cluster of over 1,800 islands straddling the Ontario-New York border — is a different kind of Ontario escape from the lake-country trips further north: history-heavy, water-focused in a river rather than lake sense, and centered on genuinely distinctive sights like Boldt Castle, an unfinished early-1900s mansion with a story worth knowing before you see it. This itinerary pairs the region with Kingston, a limestone-built former capital of Canada with its own strong historic core, about 25 minutes from Gananoque, the Thousand Islands’ main gateway town.
| Where | Kingston then Gananoque, eastern Ontario |
| Cost | around $170–220 CAD/person/day |
| Getting there | VIA Rail reaches Kingston; car helps for the Parkway |
| Best time | June–September for the full cruise schedule |
| Booking | a few days to a week ahead for cruises |
A car helps here but is somewhat less essential than in Muskoka or Prince Edward County — VIA Rail connects Toronto to Kingston directly, and once in the region, Gananoque’s compact downtown and cruise docks are walkable. That said, having a car makes the drive along the scenic Thousand Islands Parkway and stops like Ivy Lea meaningfully easier. Budget roughly $170–220 CAD per person per day at a mid-range pace — Kingston’s hotels run $150–260 CAD/night, and Gananoque’s smaller inns are similar or slightly less.
If you’re arriving by train and don’t want to rent a car for the whole trip, a taxi or short-term rental just for Day 2’s Gananoque leg is a reasonable middle ground — Kingston to Gananoque taxis run roughly $35–50 CAD one-way, cheaper than a full multi-day car rental if that’s the only leg where you genuinely need one.
What to pack for this trip
Beyond a passport if you’re planning to disembark at Boldt Castle, a light jacket or windbreaker is worth packing regardless of season — the river is noticeably cooler once any of the cruises are underway, even on a hot summer day. Comfortable walking shoes matter for Kingston’s old town cobblestones and Fort Henry’s grounds, and a light rain layer covers both the region’s occasional summer showers and cooler spring or fall cruise conditions. If you’re touring Fort Henry’s grounds, sun protection is worth having, since much of the site is open with limited shade.
Getting there from Toronto
Whether you’re driving or taking VIA Rail, plan to leave Toronto by mid-morning to arrive in Kingston with a genuine afternoon to explore rather than just enough time to check into your hotel. The 401 drive is straightforward highway driving with no notable traffic bottlenecks outside rush-hour windows around Toronto itself; VIA Rail’s Kingston service runs multiple daily departures, with the mid-morning trains generally the least crowded.
Day 1: Kingston
Drive about 2.5 hours from Toronto (or take VIA Rail, roughly 2.5 hours) into Kingston, then spend the afternoon in the city’s old town — limestone buildings dating to the 19th century, when Kingston briefly served as the capital of the Province of Canada. Fort Henry, a restored British fortification overlooking the harbor, is worth a visit if you have a couple of hours; its summer sunset ceremonies (typically Wednesday evenings in July and August) are a well-known local draw worth timing your visit around if the dates align.
The fort’s guided tours cover Kingston’s role as a former capital and its military history along the St. Lawrence, giving useful context for the region before you head out on the water the next day. For dinner, Chez Piggy, set in a converted 19th-century livery stable in the old town, is a long-standing local favorite. The Kingston day trip from Toronto guide and things to do in Kingston guide both go deeper on the city’s historic sites if you want a fuller day here before moving on.
Day 2: Gananoque and the Thousand Islands cruise
Drive about 25 minutes from Kingston to Gananoque, the main base for exploring the islands themselves. The 1000 Islands Cruise with Optional Boldt Castle Entry is the region’s signature activity — a scenic cruise weaving between the islands with the option to disembark at Boldt Castle, built by hotelier George Boldt as a gift for his wife and abandoned unfinished after her sudden death in 1904, a genuinely striking and slightly melancholy structure now open to visitors.
For a shorter version that skips the castle stop, the 1000 Islands Highlights Scenic Cruise departs from Gananoque or nearby Ivy Lea and covers the same island-hopping scenery in a tighter window, useful if you’re short on time or traveling with younger kids who won’t sit through a longer cruise.
If you’re visiting on a summer evening and want something different, the 1000 Islands Fireworks Cruise runs on select dates and combines the same river scenery with an evening fireworks display, worth checking the current schedule for if your visit lines up. Spend the rest of the day in Gananoque’s small downtown, which has a modest but decent collection of restaurants along the waterfront. The town’s compact size means you can comfortably walk from your hotel to the cruise docks and back without needing a car for this specific day, even if you drove in from Kingston that morning — worth knowing if parking near the waterfront is limited during a busy summer weekend.
If your visit falls on a day without a fireworks cruise scheduled, an early dinner followed by a walk along the Gananoque waterfront at sunset is a pleasant, unstructured way to close out the day — the town’s small scale means this doesn’t take more than 30–45 minutes to cover thoroughly.
Day 3: Ivy Lea and the Thousand Islands Parkway, then head back
Drive the Thousand Islands Parkway from Gananoque toward Ivy Lea, a scenic alternative to Highway 401 that hugs the river and offers regular pull-offs with island views. The 2-Hour Two Castle 1000 Islands Scenic Cruise from Ivy Lea departs from this quieter access point and covers both Boldt Castle and Singer Castle, a second, smaller island fortress with its own guided-tour access — a good pick if you want a more thorough castle-focused cruise than Day 2’s option and didn’t get to both on the first day.
From Ivy Lea, it’s a straightforward drive back to Toronto, roughly 3 hours via the 401, or continue on to Ottawa (about 1.5–2 hours further east) if you’re extending this into a longer eastern Ontario trip.
Comparing cruise options
The region’s four main cruise products differ mainly in length and how many castles they include: the standard Gananoque cruise with Boldt Castle is the most popular single option; the highlights cruise trims the castle stop for a shorter outing; the Ivy Lea two-castle cruise adds Singer Castle for history-focused visitors; and the fireworks cruise is a seasonal evening option rather than a daytime sightseeing trip. Most visitors do one, not multiple, unless castles specifically are the trip’s main draw.
| Standard cruise | Highlights cruise | Ivy Lea two-castle | Fireworks cruise | |
|---|---|---|---|---|
| Castles included | Boldt Castle (optional stop) | None | Boldt + Singer Castle | None |
| Length | Longest of the daytime options | Shortest | Long, most thorough | Evening only |
| Best for | First-time visitors | Kids, time-pressed visitors | History enthusiasts, repeat visitors | Summer evenings, special occasions |
For a first visit, the standard Boldt Castle cruise is the strongest single choice — it balances length, cost and the region’s signature sight without requiring two separate cruise bookings. Repeat visitors, or those with a genuine interest in the region’s history beyond the headline castle, get more value from the Ivy Lea two-castle option, since Singer Castle’s guided interior tour goes deeper into the era’s architecture and design than a pass-by view from the water.
Deciding whether to bring a car or rely on the train
VIA Rail’s direct Kingston service makes this one of the more transit-friendly itineraries on this site, and it’s a genuinely reasonable choice if you’d rather not drive at all — Kingston’s old town and Gananoque’s downtown are both walkable once you’re there, and a short taxi covers the 25-minute hop between them. The tradeoff is Day 3’s scenic Thousand Islands Parkway drive toward Ivy Lea, which is meaningfully harder to do without your own car; if that stretch isn’t a priority, skipping it and returning to Toronto directly from Gananoque or Kingston by train is a perfectly workable alternative to the itinerary as written.
The region’s backstory, briefly
The Thousand Islands’ distinctive mix of Gilded Age mansions and modest cottages dates to the late 19th century, when the area became a fashionable summer retreat for wealthy American and Canadian families arriving by steamship from cities along the Great Lakes and the eastern seaboard. Boldt Castle is the most famous relic of that era, but the river is dotted with dozens of smaller island homes from the same period, many still privately owned — part of what makes the cruise genuinely interesting beyond just scenery, since your guide will typically point out several along the route.
Extending this trip further east
If you have an extra day or two, continuing on to Ottawa from Ivy Lea or Kingston (roughly 1.5–2 hours further) is a natural extension, turning this into the eastern leg of a longer Ontario road trip — see the standalone Toronto to Ottawa: capital escape itinerary for how that half of the trip works on its own, or the 7-day Ontario road trip, which already includes both the Thousand Islands and Ottawa on a single longer loop.
Frequently asked questions about this Thousand Islands and Kingston itinerary
Do I need a car for this trip?
It helps but isn’t strictly required — VIA Rail reaches Kingston directly from Toronto, and Gananoque’s downtown and cruise docks are walkable once there. A car makes the scenic Thousand Islands Parkway and Ivy Lea stops significantly easier to reach on your own schedule.
Is Boldt Castle worth visiting?
Most visitors find it genuinely worthwhile, both for the building itself and its backstory — an unfinished early-1900s mansion abandoned after the death of the owner’s wife, which gives it a distinctly different character from a standard historic-home tour. Note that Boldt Castle sits on the US side of the border, so bring a passport if you plan to disembark there rather than just view it from the water.
How long should I spend in this region?
Three days is comfortable for Kingston’s old town plus one full day on the water; two days works if you skip Kingston’s historic sites and focus purely on the islands and cruises. A single day trip from Toronto is also possible but tight — see the Thousand Islands day trip from Toronto guide for that compressed version.
What’s the best time of year to visit?
June through September covers the region’s full cruise schedule and warmest weather. Early fall (September into early October) adds foliage color along the riverbanks with noticeably fewer crowds than peak summer.
Can I visit both Boldt Castle and Singer Castle in one trip?
Yes — the Ivy Lea two-castle cruise on Day 3 covers both in a single outing, or you can split them across two separate cruise days if you’d rather not rush either stop.
Is this itinerary suitable for a family with kids?
Yes, particularly the shorter highlights cruise, which keeps the on-water time tighter for younger attention spans. Fort Henry’s summer programming in Kingston is also generally well-suited to families.
Do I need a passport for this trip?
Not for the standard cruises that stay on the Canadian side, but yes if you plan to disembark at Boldt Castle, which sits on Heart Island on the US side of the border — bring a valid passport if you want to actually step onto the island rather than just view it from the water.
How cold does it get on the water?
Even on a warm summer day, expect it to feel noticeably cooler on the cruise itself, especially once the boat is moving — a light jacket or windbreaker is worth having even in July and August. Spring and fall cruises can be genuinely chilly, so dress in layers if you’re visiting outside peak summer.
What’s the best month for photography on the cruises?
Late September into early October combines fall foliage along the shoreline with the region’s still-active cruise schedule, generally producing the most photogenic combination of the season. Midsummer offers the most reliable weather and longest daylight, though the greenery is more uniform and less visually striking than the fall color.
Is Kingston worth a standalone trip without the islands portion?
Yes — Kingston’s old town, Fort Henry and university-town atmosphere hold up as a destination on their own, and the standalone Kingston day trip from Toronto guide covers a version of this trip that skips the islands cruise entirely if that’s not the priority.
