TREKKING THE GR20 CORSICA (CICERONE) - Dillon

Corsica Trekking GR20 - Trailblazer

Among the many trails that penetrate its remotest corners, the GR20, following the island's watershed, is a high-level route that has won an international reputation as being Europe's most challenging long-distance path.

Slicing diagonally across Corsica's jagged spine, the legendary red-and-white waymarks of the GR20 guide trekkers across a succession of snow-streaked passes, Alpine meadows, massive boulder fields and pristine forests of pine and oak - often within sight of the sea. Physically demanding from start to finish, it's a superlative 170km, two-week trek.
