The Monte Cinto
The Monte Cinto is the highest summit on the island, it is 2706m alt. It is accessible from both the Niolu valley and Haut Asco.
The GR20 leads from Haut Asco, which is a ski station, up to the Monte Cinto flanks and over the ridge. If you want to do the summit, you have to add on extra time and it is off the actual GR trail. Following a tragic accident in the Summer of 2015 this new itinerary has replaced the original Cirque de Solitude route. It has been waymarked in red and white and at the time of writing this, it is the official and permanent route.
Walking to the Monte Cinto
Walking to the Monte Cinto summit from the North Side
You can walk up to the Monte Cinto summit from the ski station Haut Asco which is accessible by car. The walk is now officially part of the GR20 and is way marked red and white up to the ridge but not up to the summit itself. From Haut Asco to the summit and back is about 12km, 1400m up and 1400m down. In good weather and walking at a regular pace, this is a full on day walk.
From Asco Stagnu, you set out from the car park and walk upstream, along the Tighiettu mountain torrent. You will come to Bocca Borba at 2300m and then the Pointe des Eboulis at 2607m. Here you separate from the GR20 you turn left in the direction of the ridge. The itinerary will take you down hill some way before you attack the last pull up to the summit.
Walking to the Monte Cinto summit from the South Side
It is also possible to do the Monte Cinto from the South side, however, for this you set out from the Refuge de l’Erco but you need a ride in a 4 wheel drive to get up there.
