Trail
Trail n°18 : Saint-Martin - Ossona - Pont de Riva
Saint-Martin/Suen
Starting from the village of Saint-Martin, this route takes you down into the impressive Borgne gorges. The lond descent unfolds in two stages, with a short break among the chalet of Sevanne halfway down.
The trail is narrow and steep. You will then follow the river, enjoying beautiful views over the valley floor. THe ascent that follows also comes in two parts : steep at first from the riverbank, then a more moderate path allows you to catch your breath before the final climb.
Please note : special caution is advised for those sensitive to heights. The La Luette footbridge is stunning, but can feel quite impressive.
