Canyon des Portes de l'Enfer, Natural canyon in Saint-Narcisse-de-Rimouski, Canada.

Canyon des Portes de l'Enfer is a gorge of the Rimouski River in Saint-Narcisse-de-Rimouski, begun by the 20-metre Grand-Sault waterfall and running nearly 5 km between narrow, abrupt walls that reach 90 metres. A 63-metre suspension bridge built in 1996 links the two banks.

The region once served as a center for the timber trade, with log drivers using the Rimouski River to transport wood to mills. This industry shaped the area's economy and settlement patterns for generations.

The trails along the water interpret the history of log driving (drave), once practised on the Rimouski River. Panels and displays along the route explain how timber was floated downstream, a trade that marked the region.

Trails for walkers and cyclists follow the Rimouski River through the gorge, and a 63-metre suspension bridge built in 1996 links the two banks. The site has been open to visitors since 1990. Trailside panels explain the history of log driving, once practised on this river.

The canyon begins at the Grand-Sault, a waterfall 20 metres high that marks the entrance to the gorge. The site has been open to visitors since 1990, and the 63-metre suspension bridge was built in 1996.
