The 4th largest island in the Mediterranean, Corsica is located west of Italy, south-east of France and north of the island of Sardinia. Corsica (with Sardinia) was once a Roman province and was also ruled by a number of Italian republics (Pisa, Genoa) until as recently as 1729. The island then enjoyed a brief independence before being incorporated within France - it is today a French region. Sometimes referred to as the ' Mountain in the Sea', Corsica rises spectacularly out of the Mediterrean to a high point at Monte Cinto (2706m / 8878ft). The island has little flat land, numerous granite peaks and a generally very rugged terrain. One of the greatest of the French Grande Randonee hiking routes, the GR20, cuts across the island south-east to north-west and provides a tough 2-week challenge for mountain walkers. Mountain bikers can also take advantage of Corsica's high valley trails with their own 'Coast to Coast' route. With its mix of Italian and French cultural heritage, Corsica is a unique and appealing adventure travel destination.
