Choosing Your Route: Erie Canal, Oswego, or Triangle Loop?
How to Pick the Right Path from New York to Lake Ontario
If you’re approaching the New York State Canal System from the Hudson River, you’ve got options. This stretch of the Great Loop—roughly 500 miles from New York Harbor to Kingston, Ontario—can be customized based on your boat’s air draft, your timeline, and the kind of adventure you’re craving.
There are three main routing options through this region, and each one offers a very different experience. Whether you’re looking to see as much as possible or keep it simple, here’s how to choose the route that’s right for your boat and your crew.
🗺️ Route 1: Erie Canal All the Way to Lake Erie
Clearance Requirement: 15 feet or less
Experience Level: Great for inland explorers and history buffs
Route Highlights: Albany, Waterford, Rome, Lockport, Buffalo, Lake Erie
This route takes you through the full length of the Erie Canal, from the Hudson River at Waterford, across upstate New York, and into Lake Erie at Buffalo. If your boat can clear the 15-foot bridges, this route gives you the full classic canal experience. It’s slow-paced, scenic, and packed with small towns, locks, and park walls to tie up along the way.
Expect lots of locks, some narrow channels, and plenty of friendly locals cheering you on from canal banks. This is a great choice if you’re in no rush and want to dive into the historical heart of America’s canal system.
🚤 Route 2: Erie Canal + Oswego Canal to Lake Ontario
Clearance Requirement: 20 feet or less
Experience Level: Popular route for most Loopers and sailboats with masts down
Route Highlights: Waterford, Erie Canal to Three Rivers Junction, Oswego Canal to Oswego, Lake Ontario
This is the most common route for Loopers with air drafts over 15 feet but under 20. You’ll head west on the Erie Canal from Waterford, then turn north onto the Oswego Canal, which leads to Oswego and Lake Ontario.
It’s a straightforward, well-traveled path with about 30 locks total and easy access to mast-stepping services on either end if you’re sailing. The Oswego Canal is a bit shorter and less traveled than the western Erie, and it gets you back to open water sooner.
⚓ Pro tip: If you’re looking for a solid balance between inland canal cruising and getting back to big lakes, this route delivers.
🌉 Route 3: The Triangle Loop via Lake Champlain and the St. Lawrence Seaway
Clearance Requirement: 17 feet or less
Experience Level: Great for adventurers with time to spare and a love for Canada
Route Highlights: Lake Champlain, Montreal, Quebec City, St. Lawrence River, Rideau Canal, Lake Ontario
Ready to explore French Canada and add an international twist to your Great Loop? The Triangle Loop offers exactly that. Instead of turning west into the Erie Canal, you’ll stay on the Hudson River and continue north on the Champlain Canal, through Lake Champlain, and up into the St. Lawrence River. From there, you’ll cruise west through Montreal, Quebec, and the Rideau Canal, eventually looping down into Lake Ontario.
This route requires an air draft of 17 feet or less, so taller boats will still need to unstep their masts, but the payoff is an incredible cultural and scenic experience. You’ll see a very different side of the Loop, including Francophone cities, international ports, and the wide waters of the St. Lawrence.
🍁 A few notes: You’ll need to clear Canadian customs, brush up on French signage (Google Translate helps), and plan for slightly more complex navigation in fast-moving waterways. But it’s absolutely worth it for adventurous crews.
⏰ Timing Tips & Seasonal Considerations
Whichever route you choose, late May to early June is the sweet spot for transiting the New York canals. The Erie and Oswego Canals usually open mid-May, and water levels, weather, and boater traffic tend to be favorable in early summer.
Here’s a quick seasonal rundown:
Late Spring / Early Summer: Ideal for all routes; locks are open, towns are welcoming, and crowds haven’t peaked yet.
July / August: Great weather but more boat traffic and higher chances of sharing walls and anchorages.
After Labor Day: Canals are still open, but some services begin to wind down. Watch for shorter hours at locks or bridge openings.
