Around 12km southwest of St-Benoît along the road towards Plaine-des-Palmistes, is the 3km road to Grand Étang (Big Pond). This pretty picnic spot lies at the bottom of an almost vertical ridge separating it from the Rivière des Marsouins valley. Most people simply walk around the lake, following a well-defined path. It's muddy in places, but shouldn't take more than three hours from the car park, including a side trip to an impressive waterfall .
