Based at an 18th-century stone chalet in the village of Barèges in the French Pyrenees, Mountainbug runs low impact snowshoeing trips that include tracking ermine, hare, isard and fox, and ski-touring programmes that are designed for skiers to discover the winter wonderland without using powered lifts, staying overnight in solar-powered mountain refuges. In Spring, the owners also run walking holidays focusing on identifying wild flowers, birds and butterflies
