This picture was taken in November. When snow covers the markers, the route becomes very difficult to trace

Even without thunderstorms the heat alone can be severe at times, causing problems of thirst, dehydration, sunburn and sunstroke. Seasonal streams dry up completely, so that a full day’s ration of water needs to be carried. The recommended minimum is two litres, but three or four may be needed, so take careful note of the availability of water sources in the middle of the day, where these are available. At either side of the peak summer period trekkers can take advantage of cooler, clear conditions.

The onset of winter sees snow covering the paths, obliterating the trails and waymarks, making most slopes too dangerous to negotiate. Conditions may be truly Alpine. In general, consider the GR20 closed to ordinary trekkers from mid-October to the end of May, although much depends on the severity of the winter months. Bear in mind that it can snow in the mountains in summer, although this is very rare and any snow cover will be very short-lived.
