The GR20 Integral

Finally try the GR20 Integral experience in 14 days!

Reception at Calvi station at 9 a.m.
End of course on Saturday, shuttle service between Conca and Porto Vecchio, dispersal in Porto Vecchio.

Attempting the GR20 Integral is the promise of a mythical crossing through the heart of the Corsican massif. It is indeed the most difficult hiking trail in Europe. Famous for its stunning elevation changes but also for its breathtaking landscapes.

The most daring hikers can climb dizzying peaks such as Monte Cintu at 2,706m, the highest point in Corsica, and relax on the banks of the beautiful pools of Manganellu and Agnone, where a deep tranquility reigns. The granite barrier shelters many natural treasures, from the famous larici pines to the charming pozzines at altitude, one can thus never stop marveling.

Between the different stages on the GR20 Integral course, hikers can also enjoy a well-deserved rest in the refuges and sheepfolds. In fact, these then become high places of human exchange where one comes to restock but above all to recharge.
