Les Houches are easily accessible from France (A41 highway), from Switzerland
(Martigny and Col des Montets).

the viaduct, bear right by the first road out for "Les Houches Les Trabets".
When arriving at the cable car station "Bellevue", turn right and continue
upwards (roughly 2 km starting from the teleferic). 500m after the cable
car station "Prarion", turn left and follow small arrows at crossroads.
Continue up to the end of Route de la Côte des Chavants. Here you
are!
