At an elevation of 2,579 metres, Grand Laus is the biggest of the three Malrif lakes. It nestles amid exceptional surroundings against the backdrop of the 3,841-metre-high Mont Viso. Pick up the GR58 hiking trail behind the gîte to follow a balcony path above the River Guil to the Malrif chapel, into the Malrif valley, then on to the hamlet of the same name. Continue on the same path to the Replat des Bertins (2,050 metres) and cross the wooden bridge. The easy zigzagging trail leads up to a plateau where the real ascent begins in a grassy valley. This is the sunny side of the mountain, so we recommend you leave early in the morning to avoid the hottest part of the day. As you approach the end of your climb, a cross on the right (at a distance) announces that Lake Grand Laus is not far away.
