The Best Paddling Routes in Ontario You Probably Haven't Tried
Every paddler in Ontario knows the usual suspects: Algonquin's canoe routes, the French River, the Muskoka chain. These are outstanding trips for good reason. But Ontario has thousands of kilometres of navigable waterways, and some of the most rewarding routes sit well outside the popular guidebooks. Over the past decade, I've paddled many of them, and the ones that stay with me are rarely the famous ones.
What follows is a curated list of routes that deserve more attention. Some are day trips. Others stretch into multiday expeditions. All of them offer something that the crowded portages of peak season simply cannot: solitude, surprise, and water that feels like it belongs to you alone.
The Magnetawan River: Burk's Falls to Ahmic Lake
The Magnetawan gets overshadowed by the French River to its north and the Muskoka waterways to its south. That's a mistake. The stretch from Burk's Falls downstream to Ahmic Lake covers roughly 40 kilometres of river paddling through mixed forest, with several short portages around rapids and one memorable canyon section where granite walls rise on both sides. The current is gentle enough for intermediate paddlers, and the camping spots along Crown land sections are well spaced.
The best time to run this route is late June through September. Spring runoff can make the rapids more technical than most recreational paddlers want. Water levels are tracked by the Government of Canada's Water Office, which publishes real-time flow data for the Magnetawan and dozens of other Ontario rivers.
The Napanee River: A Limestone Corridor
South of the Canadian Shield, most paddlers assume the landscape gets too flat to be interesting. The Napanee River proves otherwise. Starting near the village of Camden East and winding down to the town of Napanee, this route passes through a limestone valley with small waterfalls, tall cedars, and surprisingly clear water. The entire run is about 25 kilometres and can be done in a long day or a relaxed overnight.
What makes the Napanee stand out is the geology. The exposed limestone creates ledges and shallow pools that feel more like a southern Appalachian creek than central Ontario. There are a few low-head dams that require short carries, and access points are well marked thanks to the local conservation authority.
Lake St. Peter to Bancroft via the York River
This route starts at Lake St. Peter Provincial Park and follows the York River south toward Bancroft. It's a two to three day trip covering about 50 kilometres, with portages that are short but occasionally brushy. The York River is narrow and winding, with long sections of stillwater interrupted by Class I rapids. Camping is available at designated sites within the provincial park boundary and on Crown land beyond it.
The appeal here is the feeling of remoteness. The York River corridor sees minimal traffic, and the mixed boreal forest along its banks is home to moose, beaver, and the occasional otter. If you're looking for a canoe trip that feels backcountry without requiring a float plane, this is it.
Kawartha Highlands: Bottle and Sucker Lakes Loop
The Kawartha Highlands Provincial Park is gaining recognition, but specific routes within it remain underused. The loop connecting Bottle Lake, Sucker Lake, and Crab Lake via a series of portages is one of the finest three-day canoe trips in southern Ontario. The portages are well maintained, the lakes are clear and swimmable, and the campsites sit on exposed granite points with views that rival anything in Algonquin.
Access is from the Bottle Creek access point off County Road 507. Permits are required and can be reserved through Ontario Parks. Weekend spots fill up quickly in July and August, so midweek trips are advisable.
The Spanish River: Biscotasing to Agnew Lake
For experienced paddlers seeking a longer expedition, the Spanish River from Biscotasing south to Agnew Lake is one of Ontario's great underpaddled routes. This is a five to seven day trip through remote boreal forest, with significant whitewater sections that range from Class I to Class III depending on water levels. The river drops roughly 150 metres over its course, and the combination of big rapids, quiet pools, and vast wilderness makes it feel more like a northern Manitoba expedition than a trip in Ontario.
Shuttle logistics are the main barrier. Biscotasing is accessible only by rail or a long gravel road, and you'll need to arrange vehicle placement at Agnew Lake. Several outfitters in the Sudbury area offer shuttle services. This is not a beginner route, but for competent paddlers, it is extraordinary.
Bonnechere River: Round Lake to Renfrew
The Bonnechere flows through the Ottawa Valley and offers a gentle two-day float from Round Lake Centre downstream to the town of Renfrew. The river passes through farmland, small patches of forest, and the scenic Fourth Chute, where a portage trail leads around a significant waterfall. The paddling is easy, the scenery is pastoral, and the trip ends in a town with restaurants and accommodation.
This route works well for families and paddlers who prefer a river trip without heavy portaging. Access at Round Lake is straightforward, and there are several municipal parks along the route where you can stop for lunch or stretch your legs.
Planning Your Trip
Before heading out on any of these routes, a few practical considerations matter. Water levels fluctuate throughout the season, and what's a pleasant paddle in July might be a scrape-fest by late August. Always check current conditions. Carry detailed maps or download GPS tracks, as cell coverage is nonexistent on most of these routes.
If you're new to multiday paddling, consider starting with one of the beginner river routes in Ontario before tackling the longer expeditions listed here. And if Georgian Bay is more your speed, the launch points around Georgian Bay offer world-class day paddling with easier logistics.
For paddlers who prefer flatwater, Ontario has an equally impressive collection of calm water spots that work beautifully for both canoes and stand-up paddleboards. The key is getting off the beaten path. Ontario's waterways reward those who look beyond the guidebook favourites.
Whether you plan a full expedition or a simple day trip, the province's public waterfront access points make it easier than ever to find a place to put in. Just remember to leave each site cleaner than you found it. These quiet routes stay quiet because the people who paddle them take care of them.
