A guided version of the complete route of the mythical GR20 accompanied by an English speaking guide. 

Walk the complete GR20 in Corsica with a guide, the finest and most probably the hardest mountain hiking route in Europe, this is a classic trek rising from the Mediterranean sea, with granite peaks soaring to over 2600m. Corsica is known as 'the Mountain in the sea'. Over the course of 14 days we will cover a total of 180km of mountainous terrain, with approx 12,000m altitude ascent and descent, this is the entire GR20 route, from Conca in the South to Calenzana in the north. For the Southern half of the trek you have access to your bags everynight, for the Northern half, you will need to carry overnight gear. You need to be fit and ready to walk this most challenging hike.

Day 2

Conca to Bavella

This first day is really hard and a good introduction to the pace and the challenge ahead. The trail leads uphill from the village of Conca, we take your overnight gear on to the next night stop so you don’t have to carry it. The GR20 follows the traces of an ancient transhumance route through the rocky landscape of pines and granite blocks. The route continues to the Paliri refuge at just over 1000m altitude, then crosses the Finosa col before arriving at the hamlet of Bavella below the mighty Bavella needles. Access to bags.

Bavella to Cuscionu Plateau

Today is a challenging day from the high mountain pass, the Col de Bavella, before dawn you take the trail that is called the Alpine variant. It leads steeply uphill before passing at the base of several granite pinnacles. You plunge down into the valley before following an easy trail through the woods towards Asinao refuge before heading steeply up to the magnificent ridge line of Monte Alcudina, with the summit at 2134m altitude. You leave the high ground and head down towards the famous Cuscione plateau. This is the largest plateau on the island. Your night stop is a shepherd’s cabin situated on the edge of the plateau.

Cuscionu plateau to Cozzano

Today you pick up the trail on the plateau and cross the wide open green pasture with it’s streams and little water holes. You make your way uphill through an age old forest of dwarf oak trees up to the Col de l’Agnone. From here, you start possibly one of the best ridge walks, it is very exposed, the trail is ambitious and it is hard to imagine that there is a way through. The granite has been wonderfully sculpted by the elements and the decor is awesome. The trail topples back and forth over the ridge, to one side then the other. At the end of the day we drop down to the village of Cozzano, a hive of activity in the heart of the mountains. Access to bags.

Col de Verde to Vizzavona

Today's walk is essentially traversing the flanks of the dominating mountain, the Monte Renosu. You continue to Bocca Palmente 1640m, from where on a clear day the views are exceptional, the looming massifs of the Monte d’Oro and the Rotondu tower above. You drop down into a thick forest of pine and beech trees for a relaxing descent, the trail loops back and forth lacing down to Vizzavona (920m) the midway point of the GR20. Access to bags.

The path leads alongside the Cascade des Anglais up to Muratellu, affording stunning views of the Monte Rotondu, The high level route follows the ridge, via the summit of Pinzi Corbini (2021m), to Petra Piana refuge (1840m).  This is a short but challenging ridge section, steep and exposed.  In bad weather there is an alternative lower valley option that will be taken direct to Petra Piana.

The GR20 is well-marked, leading gently uphill, a relaxing easy walk through beech woods, and across the green spongy turf to the Lac de Nino. A morning stop to have a snack and relax on the banks of the lake.  At 1743m this glacier lake is in a lovely, sheltered bucolic spot, surrounded by spongy peat, with runnels of water and wells, ideal grazing ground for ponies and other animals in the summer. The air is fresh, tinged with the scent of alder and the fragrance of the high mountains. You drop down at the Col St Pierre, to join a flat horse shoe shaped trail to Castel di Vergio, the island’s small ski station.  Access to bags.

Day 10

Col de Vergio to Melarie Valley

The GR20 trail follows the Golu torrent up the valley towards its source. Mid way up the valley, your route crosses the torrent, a good place to take a break on the smooth sun-baked rocks, a paddle and a swim for the brave. The trail shortly leaves the floor of the valley and heads up to the ridge line. From here there are clear views of the villages dotted on the west coast and the indented outline of the island in the sea. The refuge Ciuttolu di I Mori (2000m), the highest refuge in Corsica, is situated between two daunting mountains the Tafanatu and Paglia Orba. From the refuge the GR20 falls away steeply downhill, to Vallone. No access to bags.

Day 11

Melarie Valley to Haut Asco

Today is a tough, high altitude mountain walk.   You make your way uphill progressively to the foothills of the Monte Cinto, the highest summit on the island.  The climb is steep, rocky and slow.  After a couple of hours, you arrive at Bocca Crucetta, a ridge leads to the daunting ‘Pointe des Eboulis’ at 2607m this is the highest point on the GR20, the view is absolutely spectacular.  From here, the path literally plunges down to the small lake the other side.  The trail continues downhill, the scree, the rocks and austere décor gives way to a river and woods as you approach the old ski station of Haut-Asco. Access to bags.
