Rain, wind and temperature are measured over the 8 h in the middle of the day, on a historical baseline of 45 observations (Open-Meteo). It is a measuring window, not the length of your day: each day of the programme counts 12 h of usable time.
The itinerary, day by day
5 stages over 7 days, in the order of the days. A stage appears on the day you first reach it: you sleep several nights at some, and a day trip leaves from your base and brings you back to it. Each day has its own page.
Every day of this trip has 12 h of usable time. Room to breathe — we have not padded these days to fill them: the free time left is part of the trip.
