Behind the Scenes
This interactive Thousand Islands logistics map helps visualize how Gananoque, Ivy Lea, Rockport, Mallorytown, Brockville, and the surrounding river communities connect along the Canadian side of the St. Lawrence River.
Intent
This Thousand Islands logistics map is a practical guide to the geography of the Thousand Islands on the Canadian side. It is for travellers who want to understand where the region is located, how Gananoque fits into the landscape, and how the Canadian side differs from the U.S. side before planning a cruise, scenic drive, photography stop, or overnight stay.
Quick Facts
The Thousand Islands region stretches along the St. Lawrence River between Kingston, Gananoque, Ivy Lea, Rockport, Mallorytown, and Brockville.
Gananoque is the main gateway town on the Canadian side for cruises, accommodations, restaurants, and easy access to the river.
This is not one compact park or single town. It is a long river corridor made up of islands, mainland access points, scenic roads, docks, and small communities.
The Thousand Islands are shared by Canada and the United States, with the international border running through the river.

Is This Thousand Islands Logistics Map for You?
This guide is for travellers who want to understand the Canadian side of the Thousand Islands before booking anything.
It is especially useful if you are searching for a logistics map of the Thousand Islands Canada side, wondering where Gananoque is located, comparing the Canadian and U.S. sides, or trying to plan a cruise, fall drive, helicopter tour, photography stop, or overnight stay without getting lost in the geography.
It is also useful for travellers who prefer a slower pace, scenic drives, easy river access, and practical planning instead of trying to rush the region in one quick stop.
Where Are the Thousand Islands?
The Thousand Islands are located in the St. Lawrence River between eastern Ontario and northern New York State.
The region sits between Lake Ontario and the Canada–U.S. border. It includes more than 1,800 islands of different sizes, from tiny rocky outcrops to larger islands with homes, castles, marinas, and forested shorelines.
One of the biggest points of confusion for first-time visitors is that the Thousand Islands are not one single town, park, or attraction. They stretch across a long river corridor, which is exactly why a clear Thousand Islands Canada side map matters before you start planning.
Micro-answer: The Thousand Islands are located in the St. Lawrence River between Ontario and New York, with Gananoque serving as the main gateway on the Canadian side.
Thousand Islands Map Overview
The Thousand Islands look more like a long ribbon of river communities than one compact destination.
On a map, the region follows the St. Lawrence River east from Lake Ontario. The Ontario shoreline sits on the north side, the New York shoreline sits on the south side, and the islands are scattered between the two countries.
Key features you will see on a Thousand Islands Canada side map include:
- the St. Lawrence River flowing east from Lake Ontario
- the Ontario shoreline on the Canadian side
- the New York shoreline on the U.S. side
- island clusters between the two countries
- gateway communities such as Gananoque, Ivy Lea, Mallorytown, Rockport, and Brockville
- cruise docks, park access points, scenic roads, and bridge crossings
Gananoque is the best-known reference point on the Canadian side because it works as the main access town for accommodations, restaurants, docks, cruises, and regional exploring.
Micro-answer: On a map, Gananoque is the main Canadian gateway to the Thousand Islands region.
Travel Intelligence: How the Canadian Side Actually Works
The Canadian side works best when you think of it as a corridor, not a single stop.
Gananoque is the easiest base for most visitors. From there, you can connect to cruises, waterfront walks, restaurants, hotels, and short drives toward Ivy Lea, Rockport, Mallorytown Landing, and the Thousand Islands Parkway.
For travellers arriving from Toronto, Ottawa, or Montreal, the region is very drivable. The main mistake is assuming the Thousand Islands are one compact attraction. In reality, the experience changes depending on whether you approach the region by road, boat, helicopter, or shoreline viewpoint.
What is the:
Best base: Gananoque
Best scenic drive: Thousand Islands Parkway
Best cruise access: Gananoque or Rockport
Best national park access: Mallorytown Landing
Best border-area reference: Ivy Lea and the Thousand Islands Bridge
Best photography angles: boat, helicopter, shoreline, and fall foliage viewpoints
The Canadian side is compact enough for day trips, but it is not walkable as one destination. From Gananoque, most major Canadian-side access points are within roughly 15–45 minutes by car. This makes Gananoque a practical base while still allowing visitors to explore Ivy Lea, Rockport, Thousand Islands National Park and Brockville without changing hotels.
Gananoque → Ivy Lea: ~15–20 min
Gananoque → Rockport: ~25 min
Gananoque → Mallorytown Landing: ~25–30 min
Gananoque → Brockville: ~40–45 min
Gananoque → Kingston: ~30 min
From the United States → the Thousand Islands Bridge connects Ontario with northern New York via Interstate 81 and is about 15 minutes drive from Gananoque.
Driving the 1000 Islands Parkway
The 1000 Islands Parkway follows the St. Lawrence River between Gananoque and Brockville, connecting many of the main places travellers use to explore the Canadian side of the 1000 Islands, including Gananoque, Ivy Lea, Rockport and Thousand Islands National Park.
It is one of the easiest ways to explore the region by car, with access to waterfront viewpoints, boat cruises, trails, cycling routes and smaller riverside communities along the way.
🕒 Allow: About 45–60 minutes to drive the Parkway without stops. If you are exploring communities, viewpoints or taking a cruise, allow several hours or make it part of a full day.
📍 Good stops to combine: Gananoque → Ivy Lea → Rockport → Thousand Islands National Park → Brockville.
💡 Planning tip: A recreational trail parallels much of the Parkway, making this corridor useful for both driving and cycling.
Planning Your 1000 Islands Boat Cruise
One thing that isn’t immediately obvious when planning a trip is that 1000 Islands cruises depart from different communities along the St. Lawrence River. I have taken cruises from both Gananoque and Rockport, and your departure point can change the route, timing and experience on the water.
📍 Gananoque: If you’re staying in Gananoque, consider leaving your car at the hotel and walking to the cruise departure area. Many central hotels are within walking distance for travellers comfortable with the walk, saving you from moving the car and paying for parking just for the cruise.
🚗 Parking:
Gananoque municipal lots, including 760 Stone Street and 600 King Street East, charge $8 per day, with payment available through the HONK mobile app or in person.
📍 Rockport: A smaller waterfront departure point directly along the 1000 Islands Parkway and an easy cruise stop to incorporate while exploring the region by car.
🕒 Arrival: For a scheduled cruise, I recommend arriving about 30 minutes before departure. If your boat leaves at 9:30 a.m., aim to arrive around 9:00 a.m. for parking, check-in and boarding.
💡 Roland’s tip: Choose your cruise first, then plan your driving route around the departure point. Gananoque and Rockport are close enough to combine easily with a day along the Parkway, but they aren’t interchangeable departure locations.
⚠️ Boldt Castle cruises: Boldt Castle is on the U.S. side of the border. If your cruise includes getting off the boat and visiting the castle, check the operator’s current passport, identification and border-entry requirements before travelling.
This map shows the Canadian and U.S. sides of the Thousand Islands region, with Gananoque highlighted as a primary access point.

Canadian Side vs. U.S. Side of the Thousand Islands
The Canadian and U.S. sides share the same river, but they feel different on the ground.
Canadian Side: Ontario
The Canadian side includes Gananoque, Ivy Lea, Mallorytown, Rockport, Brockville, and nearby shoreline communities.
This side is known for easy road access from Highway 401, small river towns, scenic pull-offs, boat cruises, national park access, and island clusters that often feel close to shore.
Gananoque is the most practical base for first-time visitors because it has the strongest mix of accommodations, restaurants, cruise access, and walkable river-town atmosphere.
U.S. Side: New York
The U.S. side includes Alexandria Bay, Clayton, and other river communities in northern New York State.
This side is generally known for larger marinas, broader boating infrastructure, bigger river communities in some sections, and strong access to Boldt Castle and U.S.-side attractions.
Both sides share the Thousand Islands, but the international border runs directly through the St. Lawrence River.
Micro-answer: Canada and the United States share the Thousand Islands, with the international border running through the St. Lawrence River.
Planning a Visit to Boldt Castle from Canada
Boldt Castle is on Heart Island in New York, so visiting the castle from Canada means entering the United States. The island is accessible only by water, either by an eligible sightseeing cruise or private boat.
🇺🇸 Border crossing: Heart Island is an official U.S. Port of Entry. Canadian visitors who disembark at Boldt Castle must clear U.S. Customs and carry the appropriate travel identification. Always check current U.S. entry requirements before departure.
Choose the right cruise:
Not every 1000 Islands cruise stops at Boldt Castle. Some cruises only sail past or circle Heart Island, while specific stopover cruises allow passengers to disembark and visit the castle. From the Canadian side, stopover options are available from Gananoque and Rockport.
🕒 Allow enough time: A Boldt Castle stopover is considerably different from a short sightseeing cruise. When planning your day, account for the boat trip, border processing, time to explore Heart Island and your return cruise.
💳 Payment: Boldt Castle accepts major credit cards and U.S. cash. Admission to the castle may be included with some cruise packages, so check what your ticket includes before purchasing admission separately.
🏰 Boldt Castle Yacht House: The Yacht House is separate from the main castle on Heart Island and is reached by shuttle boat. If you want to visit both, check that your cruise schedule gives you enough time before your return departure.
⚠️ Important: Cruise schedules, admission prices, border requirements and operating hours can change seasonally. Confirm current information with your cruise operator and Boldt Castle before travelling.
💡 Roland’s tip: Decide whether you want to see Boldt Castle or actually visit Boldt Castle before booking your cruise. Several tours provide excellent views from the water without stopping on Heart Island. If walking through the castle is important to you, specifically book a Boldt Castle stopover cruise.
Main Towns and Communities on the Thousand Islands Canada Side
The Canadian side is easiest to understand when you break it into gateway communities.
Kingston
Kingston marks the western gateway to the Thousand Islands corridor. While Gananoque is the more practical base for exploring the islands themselves, Kingston works well for travellers combining the Thousand Islands with a larger eastern Ontario road trip.
Gananoque
Gananoque is the main service town on the Canadian side. It sits on the north shore of the St. Lawrence River, roughly between Kingston and Brockville. It is the most common starting point for cruises, overnight stays, dining, waterfront walks, and first-time Thousand Islands exploring.
For most visitors, Gananoque is the easiest place to base yourself.
Ivy Lea
Ivy Lea is a small riverside community east of Gananoque.
It is closely tied to the Thousand Islands Parkway and the nearby international bridge crossing. It is useful as a geographic reference point because it helps visitors understand where the Canadian shoreline, scenic drive, and border corridor come together.
Mallorytown
Mallorytown sits slightly inland but matters for logistics. It provides access to Mallorytown Landing and mainland sites connected to Thousand Islands National Park. This is important because the national park is not one continuous block of land.
Rockport
Rockport is farther east and offers another strong river access point. It is a smaller village surrounded by narrow channels, island views, shoreline roads, and boat-tour access. For visitors looking for a quieter river feel, Rockport can be a strong alternative to Gananoque.
Brockville
Brockville sits farther east along the St. Lawrence River. It is not always the first town people think of when planning the Thousand Islands, but it helps define the eastern end of the Canadian-side river corridor and works well for travellers extending their route beyond Gananoque and Rockport.
Where Is Thousand Islands National Park on the Map?
Thousand Islands National Park is spread across separate mainland and island sites.
This is where many visitors get tripped up. The national park is not shown on a map as one large continuous park. Instead, it includes mainland access points such as Mallorytown Landing and island properties that may require boat access.
That scattered layout matters because many travellers assume the national park covers the entire region. It does not. The Thousand Islands region is much broader than the park itself.
Micro-answer: Thousand Islands National Park appears on the map as separate mainland and island sites, not one single block.
Parks Canada currently lists exactly those mainland locations.
Mallorytown Landing — visitor centre, boat launch, picnic area, short trails
Jones Creek — larger trail network and wetlands
Landon Bay — trails and scenic lookout
How to Get to the Thousand Islands on the Canadian Side
The Thousand Islands are easiest to reach by car from Toronto, Ottawa, Montreal, Kingston, and Brockville.
From Toronto
Drive east on Highway 401 toward Kingston, then continue toward Gananoque. The Thousand Islands region begins to feel more obvious east of Kingston as the road moves closer to the St. Lawrence River corridor. For most Toronto travellers, Gananoque is the easiest first base.
Approximate drive time: 3 hours
From Ottawa
Drive south toward the St. Lawrence River corridor, then connect toward Gananoque, Ivy Lea, or Brockville depending on your route. For Ottawa travellers, the Thousand Islands work well as a weekend escape, photography drive, or overnight river stay.
Approximate drive time: 2 hours
From Montreal
Drive west toward Brockville, then continue toward Rockport, Ivy Lea, or Gananoque.
For Montreal travellers, Brockville and Rockport can work as eastern entry points, while Gananoque remains the strongest base for cruises and overnight stays.
Approximate drive time: 2.5 hours
Thousand Islands Logistics Resilience
The Thousand Islands are easy to visit, but timing, weather, cruise schedules, and parking can shape the day quickly.
Cruise Timing
Boat cruises are one of the main reasons people visit the region.
In summer and fall, cruise departures can fill quickly, especially on weekends and during fall colour season. Book ahead when possible and arrive early enough to park, check in, and reach the dock without rushing.
Weather and River Conditions
The St. Lawrence River can feel cooler and windier than inland areas.
Bring an extra layer for boat tours, even on warm days. River wind, cloud cover, and spray can change the comfort level quickly, especially for sunset cruises or shoulder-season visits.
Parking Pressure
Gananoque waterfront parking can become busy during peak weekends.
If you are visiting for a cruise, fall foliage drive, or helicopter tour, arrive with extra time. Parking stress is the fastest way to turn a scenic river day into a small personal documentary about regret.
Border Context
The Thousand Islands are shared by Canada and the United States, but not every visit involves a border crossing.
Some cruises may pass near international waters or major landmarks, while others stay on the Canadian side. Always check your cruise route, ID requirements, and whether a passport is needed before booking.
Accessibility Notes
Some docks, older streets, shoreline paths, and boat access points may involve uneven surfaces, ramps, stairs, or narrow boarding areas.
Travellers with mobility needs should confirm dock access, washroom access, parking distance, and boarding procedures directly with the cruise or tour operator before arrival.
Photography Notes for the Thousand Islands
The Thousand Islands photograph best when you change perspective.
From the water, the region becomes intimate. You see narrow channels, island cottages, boathouses, rocky outcrops, and river reflections that are hard to understand from the road.
From above, especially during fall colour, the region finally makes geographic sense. Helicopter tours can reveal how the islands, channels, bridges, and shoreline communities fit together.
From shore, Gananoque, Rockport, Ivy Lea, and the Thousand Islands Parkway offer slower scenes: docks, boats, river bends, golden light, and layered shoreline views.
Best photography options include:
- Helicopter tours: fall foliage, island clusters, bridges, and wide river context
- Boat tours: island channels, cottages, castles, and river-level views
- Gananoque waterfront: easy access for sunrise, sunset, and town-based photography
- Rockport docks: quieter river village atmosphere
- Thousand Islands Parkway: scenic pull-offs and shoreline views
- Ivy Lea area: bridge context, river scale, and border geography
Why This Thousand Islands Map Matters
A clear Thousand Islands map helps explain the region before you arrive.
It shows where the Canadian side begins to take shape, how Gananoque, Ivy Lea, Mallorytown, Rockport, and Brockville connect along the river, and why Thousand Islands National Park appears in separate pieces rather than one solid block.
It also helps visitors understand how close the U.S. side is, why the region feels more spread out on the ground than it appears in photos, and why choosing the right base matters.
Frequently Asked Questions
The Thousand Islands are located in the St. Lawrence River between eastern Ontario and northern New York State. On the Canadian side, the main visitor corridor runs from Kingston toward Gananoque, Ivy Lea, Rockport, Mallorytown, and Brockville. Gananoque is the easiest gateway for most first-time visitors.
The Thousand Islands are shared by both Canada and the United States. The region stretches east from Lake Ontario along the St. Lawrence River, with the international border dividing the islands between Ontario and New York State. On the Canadian side, visitors can explore the region from Gananoque, Ivy Lea, Rockport, Mallorytown, and Brockville.
There are more than 1,800 islands in the Thousand Islands region. They range from tiny rocky outcrops to larger islands with homes, cottages, castles, docks, marinas, and forested landscapes. The scattered layout is one reason a map is so helpful before visiting.
Gananoque is the main gateway town on the Canadian side of the Thousand Islands. It offers the strongest combination of boat cruises, accommodations, restaurants, waterfront access, and regional road connections. For most first-time visitors, Gananoque is the easiest place to start.
Yes. Gananoque sits directly on the north shore of the St. Lawrence River and is widely considered the main access point to the Thousand Islands in Ontario. It is not the entire region, but it is the most practical Canadian base for cruises and overnight stays.
No. Thousand Islands National Park is only one part of the broader Thousand Islands region. The park is spread across separate mainland and island sites, including places such as Mallorytown Landing. The full Thousand Islands region also includes towns, roads, docks, private islands, and U.S.-side communities.
You do not need a passport to explore the Canadian side by road or take a cruise that remains entirely within Canada. A passport or other required travel documentation may be necessary if your itinerary enters the United States or includes a U.S. attraction such as Boldt Castle. Always confirm the route and documentation requirements with your tour operator before booking.
The best way to understand the Thousand Islands is to combine perspectives. Start with Gananoque or Rockport for a boat cruise, drive part of the Thousand Islands Parkway, and add a shoreline or helicopter viewpoint if time allows. The region makes more sense when seen from water, road, and above.
Yes, but a car makes the Thousand Islands much easier to explore. VIA Rail serves Kingston, Gananoque and Brockville, but places such as Ivy Lea, Rockport, Mallorytown Landing and scenic sections of the Thousand Islands Parkway are much easier to reach by car. If your goal is simply a Gananoque stay and boat cruise, a car is less essential.
Some island properties require boats, but those mainland sites don’t. Parks Canada explicitly addresses visitors without boats.
