Quite an early start as the traffic on the nearby road was noisy. Drove two and a half hours to the Chartreuse mountains and parked up in the main square car park for free. Then took a 9km round trip walk to the Chartreuse monastery. Beautiful location in the mountains and no idea how the remaining 30 monks look after such a massive complex. They sell 1.5 million bottles of chartreuse at €50 a bottle each year, so guess that helps. Such a peaceful place. Had a nice night apart from the temperature getting down to 1 and the church clock chiming every hour.
