The mountainous island of Corsica is extremely well suited to walking, and options range from difficult multi-day hikes to gentle strolls along cliff tops. The GR20 is reputed to be the best and most challenging long-distance walk in Europe, and is the most famous hike in Corsica. Fifteen days of demanding walking takes hikers along the inland granite spine of mountains dividing the island from Calenzana to Conca. Other well known, but less taxing walks include the Mare e Monti (sea to mountains) and Mare a Mare (sea to sea), trails that last between five, seven and 10 days. The area around Corte and Vizzavona boasts numerous day walks in the mountains; there are also a number of coastal walks such as the walk to Girolata on the west coast or Le Sentier des Douaniers on Cap Corse, and forests and ravines invite walkers to discover beautiful waterfalls, swimming holes and wonderful views.
The GR20 should be walked in summer, between June and September, although late snows can prevail until June, which requires a more technical approach. Generally, the peak hiking season in Corsica is between late May and early October, although naturally the more easy trails can be walked in any season.
