Les Crosets is reached via Val-d'Illiez and Champéry. The nearest mainline station is Monthey, on the Rhone valley line between Lausanne and Brig. From Monthey a regional train (AOMC) runs up the valley to Champéry; from there it is a 7-kilometre climb by road or shuttle bus to Les Crosets.
By car, take the A9 motorway along Lake Geneva and exit at Bex or Monthey, then follow signs to Val-d'Illiez and Champéry. The mountain road up to Les Crosets is steep and narrow, with hairpin bends — drive carefully in winter and carry snow chains.
The nearest international airport is Geneva, about 100 kilometres north-west and roughly 90 minutes by car or train.
