The trails, totalling 7.5 km, which run between Ollomont and the snowfields of the hamlets of Rey and Vouéce, are characterised by spectacular scenery: the imposing mountain chain that separates the top of the Ollomont Valley from Switzerland, dominated by Mont Velan (3708 m) and the Grand Combin (4314 m).
