Petawawa River
Algonquin Park Whitewater Route
Flowing from its headwaters in Algonquin Provincial Park all the way to the Ottawa River, the Petawawa River is perhaps the best-known and most dynamic river route in the park. Travelling from west to east across Algonquin, the river changes character with every kilometre, from slow, marshy meanders in its upper reaches to powerful, rushing rapids further downstream.
The Petawawa offers a wide range of route options and trip styles, making it suitable for everything from scenic wilderness travel to advanced whitewater adventures. The most popular paddling section runs between Lake Travers and Lake McManus, where the river features a mix of moving water, open lakes, and a series of rapids that range from Class I to Class IV depending on water levels. All major rapids are portaged, and as with any whitewater river, scouting is essential before attempting to run them.
Scenically, the Petawawa is one of the most rewarding trips in Algonquin Park. Deep gorges, towering granite cliffs, pine-covered ridges, and quiet backcountry campsites line the corridor, creating a constantly changing and unforgettable landscape. The river is also a productive fishery, with northern pike, muskellunge, and smallmouth bass found throughout the lower stretches.
Water levels vary significantly by season, with spring offering higher flows and more powerful whitewater, while summer and fall bring lower, more technical conditions. With its variety of route options, dramatic scenery, and true wilderness feel, the Petawawa River stands out as one of Algonquin’s premier canoe trips. Our goal is to be the go-to outfitter for Petawawa River adventures, providing the experience, equipment, and logistics to help you make the most of this iconic river.

A short jog south on Doran Road leads to the Barron Canyon Road (County Road 28), which leads west to the park.

Whitewater Routes
The most popular stretch for whitewater trippers is the section between Lake Travers and McManus Lake due to the proximity of the put-in and take-outs from each other. It is recommended to allow three days to run this section, which features Class 1 to Class IV rapids. From Lake Travers to the large rapid known as the Natch, the scenery is set amidst a forested valley. Down river from the Natch, the scenery begins to change to a more southern feel with maples and other deciduous trees lining the shoreline.
