River Description
la haute rivière Gatineau! ... allons-y!
The Upper Gatineau River flows from the Mercier Dam outflow of Réservoir Baskatong to the Grand-Remous area where Transcanadienne Route 117E crosses the Gatineau River.
The Upper Gatineau was a well-kept secret and more isolated than the well-known lower section.
Slightly more difficult, however, there are portage trails around all the major rapids and drops.
The likely best place to meet is a restaurant at the take-out found at the intersection of Routes 117 and 105.
Do remember to ask permission to use take-out. (Please be courteus in Canada or we will deny your Tim Hortons order!)
There is an Annual Gatineau Festival, typically August late! Go here for a festival river map of this section.
Note: Mileage measurements and GPS locations of all the rapids are educated guesses. This section has not yet been mapped by a GPS.
