Call it a lake and you are technically correct. Sail it for a week and the word will stop feeling adequate. Georgian Bay is 180 miles long and 80 miles wide, with a shoreline that runs over a thousand miles when you trace all its bays and inlets. It generates its own weather systems, produces waves steep enough to be genuinely unpleasant in a small boat, and contains within its borders more sailing variety — from the labyrinthine 30,000 Islands in the southeast to the glacier-carved channels of the North Channel in the north — than most cruising grounds manage over twice the distance.
Sailors who discover Georgian Bay tend to return. The cruising club network is strong, the facilities are adequate to excellent depending on where you are, and the landscape — pink granite outcrops, white pine, crystal-clear water — has a particular character that the Group of Seven painted and that sailboat sailors discover independently, usually around the third day anchored in a quiet cove on the North Channel.
The North Channel: Little Current to Killarney
The North Channel runs between the northern shore of Manitoulin Island and the Canadian mainland, roughly 120 miles from the St. Mary's River at the east end of Lake Superior to the entrance at Little Current in the west. It is consistently listed among the top ten cruising destinations in North America by everyone from Sail magazine to the cruising club guides, and the designation is not hyperbole. The combination of protected water, dramatic quartzite hills, good anchorages, and manageable distances between stops makes it the kind of destination that sailors plan vacations around.
The western approach from Lake Huron enters through Little Current on the north shore of Manitoulin Island. The eastern terminus, for most cruisers, is Killarney. In between, the channel offers Gore Bay (the main town on the north shore of Manitoulin, good provisions), Kagawong (the waterfall, the small-boat harbour), Baie Fine (the fjord-like inlet that ends in The Pool, one of the most protected anchorages anywhere), and the Benjamin Islands — pink granite islands with excellent anchoring and the kind of scenery that ends up as screensavers.
The Little Current Swing Bridge
Little Current sits at the narrows where Manitoulin Island nearly meets the mainland, and the swing bridge that carries Highway 6 across the gap is an organizing fact of life in the North Channel. The bridge opens on the hour, every hour — except during rush hour (7–9 AM and 4–6 PM on weekdays), when it does not open at all. Sailboats transiting the narrows must time their arrival accordingly.
The protocol is simple enough: arrive at the holding area before the hour, wait for the bridge to swing open (it takes a few minutes), and proceed through with the other assembled boats. The current through the narrows runs hard on a strong wind, so have your engine ready and know which way it is running before you commit. Little Current itself has a good marina, a grocery store, a hardware store, and a boatyard — it is the last full-service stop before heading east into the channel, and most boats spend at least one night here.
Manitoulin Island, which the bridge accesses, is the world's largest freshwater island and worth a walking tour in its own right. The island has a significant Anishinaabe cultural presence and the powwow at Wikwemikong, held in late July, is one of the largest traditional gatherings in Canada.
Killarney: The End of the Channel
Killarney is the destination that sailors who have done the North Channel talk about most. The town sits at the end of a protected channel cut through the La Cloche Mountains — the ancient quartzite range that forms the dramatic white hills visible from miles offshore. The hills are not high by any mountain standard (perhaps 300 metres), but their stark white quartzite against a blue sky, reflected in the clear channel water, creates a landscape of unusual visual power.
The Killarney Mountain Lodge has a dock with transient slips, a dining room, and a reputation that brings boats in from considerable distances. The town has a general store, fuel, and a small fleet of outfitters. The channel into Collins Inlet, east of Killarney, gives access to a long, protected waterway cutting deep into the mainland — spectacular, sheltered, and largely empty.
Anchoring in Killarney harbour in the evening with the white quartzite hills catching the last light, the water perfectly still, is the experience most boats come to the North Channel to find. It consistently delivers.
The 30,000 Islands
The southeastern corner of Georgian Bay, roughly between Parry Sound and Midland, contains the labyrinth of rocky islets known as the 30,000 Islands — though the actual count depends on what you define as an island and how small you're willing to count. They are, in any case, numerous. This section of Georgian Bay is a designated UNESCO World Biosphere Reserve, and from the water it reads as an infinite series of pink granite outcrops draped in white pine, separated by channels that range from wide and obvious to too narrow to take seriously.
Navigation here demands proper chartwork and attention. The channels are not always intuitive, the rocks are unforgiving, and the similarity of one island to the next makes positional awareness critical. Experienced sailors in boats they know well find this section extraordinarily rewarding — the anchorages are secluded, the swimming is excellent (the water in the inner bay warms considerably in summer), and the density of islands means you can go most of a day without seeing another boat if you choose your route carefully.
For boats not confident in their chartwork, the outer channels and marked routes are entirely adequate and still beautiful. The 30,000 Islands is not a section of Georgian Bay where you bluff your way through.
Parry Sound
Parry Sound is the largest town on Georgian Bay — a small city by most standards, but a significant amenity by Georgian Bay cruising standards. The Waubuno Channel leads north from the main bay into Parry Sound Harbour, providing a protected approach in most weather. The town has full grocery stores, marine supplies, boatyards, restaurants, and the Bobby Orr Hall of Fame (which is either a required stop or an optional one, depending on your relationship with hockey).
Parry Sound is the provisioning stop for boats heading north into the North Channel, and the last convenient resupply before the long run to Killarney. The marinas are adequate and occasionally busy on summer weekends, when Georgian Bay powerboat traffic reaches its peak. The Parry Sound Sailing Club hosts regattas and is a useful contact for local knowledge.
Getting There: The Trent-Severn
Boats based on Lake Ontario have a remarkable option for reaching Georgian Bay: the Trent-Severn Waterway, a system of 44 locks and 386 kilometres of canal and river running from Trenton on Lake Ontario to Port Severn on Georgian Bay. The transit takes ten to fourteen days at a moderate pace, passes through some of the most pleasant small-town Ontario landscape imaginable, and arrives at Georgian Bay's southeastern corner having done something genuinely historical — the waterway has been moving boats since 1920.
The locks operate mid-May through mid-October. Lock fees are paid by the day or by season, and Parks Canada manages the system with a level of organization that makes the transit remarkably smooth. Draft limit is approximately 1.5 metres (5 feet) for the full route; air draft is constrained at several bridges, so check your spar height before committing.
Boats trailering from elsewhere can launch at any number of ramps around the bay's perimeter. Midland, Collingwood, Owen Sound, and Tobermory all have launch facilities and varying levels of marina infrastructure.

Frequently Asked Questions
What is the scale of Georgian Bay and what cruising variety does it offer? Georgian Bay is 180 miles long and 80 miles wide with a shoreline exceeding 1,000 miles when all bays and inlets are traced. It ranges from the labyrinthine 30,000 Islands in the southeast — a UNESCO World Biosphere Reserve — to the glacier-carved channels of the North Channel in the north. The bay generates its own weather systems and produces waves steep enough to be unpleasant in a small boat.
What makes the North Channel consistently rated among the top ten cruising destinations in North America? The North Channel runs roughly 120 miles between Manitoulin Island's northern shore and the Canadian mainland. It offers protected water, the dramatic quartzite La Cloche Mountains, excellent anchorages including the fjord-like Baie Fine and The Pool, and the Benjamin Islands — pink granite outcrops with extraordinary scenery. The combination of landscape quality, manageable distances between stops, and reliable protection makes it a destination sailors plan vacations around.
What is the Little Current Swing Bridge and how does it affect passage planning? The Little Current bridge carries Highway 6 across the narrows where Manitoulin Island nearly meets the mainland and opens on the hour, every hour — except during weekday rush hour (7–9 AM and 4–6 PM) when it does not open at all. Sailboats transiting must time their arrival accordingly. The current through the narrows runs hard in strong wind, so have the engine ready and know the current direction before committing.
What is the Trent-Severn Waterway and how is it used to reach Georgian Bay? The Trent-Severn Waterway is a system of 44 locks and 386 kilometres running from Trenton on Lake Ontario to Port Severn on Georgian Bay. The transit takes 10–14 days at a moderate pace and arrives at Georgian Bay's southeastern corner. The locks operate mid-May through mid-October; Parks Canada manages the system. The draft limit is approximately 1.5 metres (5 feet) for the full route.
Why is careful chartwork essential in the 30,000 Islands section of Georgian Bay? The 30,000 Islands — between Parry Sound and Midland in the southeastern bay — is a labyrinth of rocky islets where the channels range from wide and obvious to too narrow to take seriously. The rocks are unforgiving and the similarity of one island to the next makes positional awareness critical. Experienced sailors find this section extraordinarily rewarding, but boats not confident in their chartwork should use the outer channels and marked routes.
