    Route Description for Lac Bleu

    The hike to Lac Bleu is on a steep trail not suitable for strollers. The hike is short and safe, so adventurous young children can often manage the hike.

    There are several trails leading to Lac Bleu, the shortest starts from La Gouille, a small village near Evolene. Parking your car can be an issue as there are only a few spots available in La Gouille, but it is possible to find some parking spots along the main road Le Pô.

    Start the hike by entering La Gouille and finding the trail signs that point you to Lac Bleu. You will then weave your way through some buildings and houses until you see the start of the trail. The trail rises steeply and has several forks along the way.

    Trail signs will point you in the right direction. Along the way, you will pass by several small unoccupied huts, which seem to be storage used by farmers. The trail continues to rise until it crosses a small bridge on one end of Lac Bleu.

    Walk around the area to find an ideal picnic spot- there are a few benches and picnic tables around the lake. Some hikers take the plunge and swim in the cool water. Enjoy your time here as you please!

    Take the same route you took to return to La Gouille. From around the lake, you have a good view of Dent de Perroc (3,676 m) across the valley. From a distance, you may also see Glacier d’ Arolla and L'Eveque (3,716 m). Enjoy the fabulous views before retracing your steps.
