The maps in this guidebook are basically diagrammatic, at a scale of 1:50,000. Transferring the route from these maps to one of the recommended walking maps should be fairly straightforward. The gradient profiles provide an immediate visual appreciation of all the ups and downs along the way.

Mountain weather

Mountain ranges have a habit of creating their own weather conditions. The mountains of Corsica boast several summits over 2000m (6560ft). In the summer months the sun beats down relentlessly on bare granite slopes, raising the temperature of the air and creating great up-draughts. This draws in cool, moist air from the Mediterranean, leading to condensation, cloud cover, rain and fearsome thunderstorms. The usual pattern is for the day to start sunny and clear, with cloud building up in the afternoon. Whether the cloud eventually results in rain or thunderstorms depends on the amount of build-up. The mountain ridges are very exposed in severe weather conditions and sudden lightning strikes have claimed trekkers’ lives.
