Unfortunately, at the time of my visit there was no guided tour and therefore no entry into the caves... The walk is still worthwhile

Superb road and vestige of the Roman road which linked Lyon to Chambéry. Today a hiking trail, this ancient Roman road can be rediscovered on foot in a sumptuous setting!
