Mare a Mare Sud (Corsica)

Mare a Mare Sud (Corsica) — the trail guide

The Mare a Mare Sud (Corsica) is a 82.4 km trek in France, typically walked in 4–5 days, with 3822 m of total ascent. It rates Moderate on our published rubric (46 m of gain per km, topping out at 1174 m).

The Mare a Mare Sud is the shortest and easiest of Corsica's three coast-to-coast walks, running roughly 82 km across the island's southern spine. From Porto-Vecchio on the east coast it climbs into the forested L'Ospédale massif, then rambles through the granite villages of the Alta Rocca — Levie, Serra-di-Scopamène, Sainte-Lucie-de-Tallano — before dropping to Propriano on the Golfe du Valinco. Walkers choose it for gîte-to-gîte comfort, orange-blazed waymarking, and a far longer season than the high GR20.
