Magnetawan River: Ahmic Bay to Georgian Bay (7 days / 74 km)

Amazing sailing view in Magnetawan River

The Magnetawan (lovingly called the Mag) is a prime southern Ontario river to run for those who want to push their whitewater skills, dust off the rust before a big trip, or try a cool route that’s not too far away, yet can still feel remote.

There are loads of fun sets, cliff jumping opportunities, waterfalls, and awesome fishing. In low water conditions, there are a lot of pin rocks, and at high water, the Mag transforms into a raging river with very powerful features.

There are a number of access points along the route, allowing you to alter the route as you’d like. Generally speaking, this route has a few longer sets / portages that can be time-consuming, but overall the days are on the shorter side.
