The heavenly blue Lac Bleu d’Arolla (2090 metres above sea level) at the head of the Val d’Hérens, owes its unique colour to the combination of algae and glacial clay. 

Choose your route: go on a largely flat walk of 1 hour 30 minutes from Arolla or a climb of 45 minutes from the village of La Gouille. Be amazed at the sight of marmots, chamois, and forests of larch and Swiss stone pine. Ideal for a family trip.
