Trekking the GR20 Corsica

Tackle one of Europe’s greatest trekking challenges on the GR20, Corsica’s legendary high-level route that runs the length of the island’s mountainous spine from Calinzana in the north to Conca in the south. Often described as Europe’s toughest trek, this 190km (118-mile) trail is best suited to experienced hikers as it follows rugged granite ridges and remote cols, with steep ascents, scrambling sections and exposure to rapidly changing mountain weather.

This expertly crafted Cicerone guidebook is the essential companion for anyone planning to tackle the GR20, whether you aim to complete the full route in 16 days or focus on one half. The trek is commonly split into the northern section, widely considered the most challenging with its rugged alpine terrain and exposed scrambles, and the southern section, which is still demanding but generally less technical.

• The GR20 is split into 16 stages (5 to 20km per stage) with high-level and low-level alternatives for some sections, so you can make the journey your own
• Detailed route descriptions and elevation profiles are supported by a separate map booklet featuring 1:25,000 IGN mapping with the route line clearly marked for navigation through Corsica's rugged mountains
• Tips from experienced author, Paddy Dillon, on safety measures, what to pack and when to go are provided, essential when tackling such a tough trek
• Accommodation listings are included for each stage, which are mainly refuges maintained by Parc Naturel Régional de Corse. Clear guidance on where advance booking is required is also provided.
• Downloadable GPX files are available for the entire trail from Calinzana to Conca, as a digital navigation option for use on smartphones and GPS devices

More than just a walk, the GR20 is a true test of endurance, resilience and spirit. With this trusted Cicerone guidebook in your pack, you’ll be fully equipped to face the challenge, embrace the unpredictability and experience the raw beauty of Corsica’s mountains. Plan well, walk wisely, and step into an adventure that will stay with you long after the final descent to the Mediterranean.
