GR20 France Corsica Travel Postcard

The GR20 (Grande Randonnée 20) in Corsica is often considered one of the toughest and most spectacular long-distance hiking trails in Europe. Stretching approximately 180 kilometres (112 miles) from Calenzana in the north to Conca in the south, the trail cuts across the mountainous spine of Corsica and showcases the island’s dramatic landscapes. Hikers traverse rugged ridgelines, steep granite peaks, alpine meadows, and dense pine forests, all while enjoying sweeping views of the Mediterranean Sea. The trail typically takes about 15 days to complete, with mountain refuges and rustic huts (called refuges or bergeries) offering basic shelter and meals along the way. What makes the GR20 especially appealing is its raw, wild nature and the sense of adventure it demands. The terrain is challenging—marked by scrambling sections, swinging footbridges, and unpredictable weather—so it's recommended for experienced and well-prepared hikers. However, the rewards are immense: solitude in the high mountains, encounters with Corsican wildlife like wild pigs and mouflons, and the chance to experience Corsican culture in small mountain villages. Whether done in full or tackled in sections, the GR20 offers an unforgettable immersion into one of France’s most rugged and beautiful regions.
