Day 2

Calenzana to Ortu di Piobbu

The GR20 crosses the massif of Bonifatu in three days, they are amongst the hardest of the whole trek. For this first day you head out from the vibrant emblematic village of Calenzana and head up through the maquis. The scenery is breathtaking, you are soon looking at the coastline and the Balagne area below.  The maquis gives way to forest, which in turn gives way to high granite mountains. This is a varied day and certainly one of the most exhausting.

Ortu di Piobbu to Carrozu

This day breaks into two clear sections, the first half crosses a basin area that is dotted with woodland. The second part is outstanding,  the ambiance is high and airy as you enter into a semi circle of high mountains.  The trail works its way around the edge of a large cirque and the panoramic view of all the highest peaks is inspiring.   From the far side of the cirque you drop down towards the refuge, a sign that you are drawing close is the box tree vegetation that thrives here. You arrive at Carrozu, surrounded by box trees, with great sunsets!

You soon change directions and start the descent towards Haut Asco, large granite blocks give way to pine tree forests as we arrive at the old ski station.

Haut Asco to Melarie Valley

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, the slopes covered in scree making for an austere landscape.  The path climbs up to the small lake and you arrive at the  ‘Pointe des Eboulis’ at 2607m this is the highest point on the GR20, the view is absolutely spectacular. After a couple of hours more, you arrive at Bocca Crucetta, a ridge and your way out down to the Melarie valley.

Leaving the plateau, the walk becomes quickly testing. You need to adapt a steady rhythm in order to get to the high mountain pass called the Brèche de Capitello (2225m) This is a delicate high section, once across the pass, the trail skirts around a series of lakes. You can enjoy great views down on Capitello lake, with its sheer granite cliffs; it’s the deepest glacier lake in Corsica,  43m.  Further on, you will spot the lac de Melo, this is an apple shaped lake surrounded with spongy lawns. You gain altitude again, going up and over another col to discover a third small lake, the Rinoso.  From the col de Muzzarela the terrain because almost lunar with great blocks of granite.  This is the last section before you arrive at the refuge.

Day 9

Petra Piana to L'Onda

This is a short but technical section, you follow the ridge and you are exposed all the time.  It’s hard to advance quickly as the trail is so rocky and challenging.  As you progress along the ridge you will traverse a series of summits, this section is known as the Pinzi Corbini.  On the West coast, way beneath you,  is the Gulf of Ajaccio.  You leave the ridge at the end of the section to drop down 20mins to the refuge and shepherd’s cabin, l’Onda.   In bad weather, particularly if it’s windy, the ridge walk is replaced by a GR20 variant that is at a lower level and leads safely down into the valley.  You arrive at l’Onda cutting out the exposed section. The refuge of L’Onda is colourful, lots of goats, sheep, mules and horses. The homemade brocciu spinach lasagna is pretty good!

L'Onda to Vizzavona

From l’Onda you will quickly arrive at the col that topples into the valley  l’Agnone.  The massif of the Monte d’Oro dominates here, it’s one of the island’s highest summits.  We drop down through the valley and arrive alongside a mountain torrent  that was particularly favored by the English at the turn of the century, the ‘Cascade des Anglais.’ If you want a stop on the way down, you can choose from one of the inviting rock pools with sun baked rocks and enticing pools.

You cross the river then head into the shade of the forest.  After a couple of hours on the flat, you pull steeply up to the ‘Alpine Variant.’ The trail passes by the foot of the high  needles that have made Bavella famous.

Day 15

Bavella to Conca

A great last day, setting out from Bavella, a trail winds through the woods to Paliri refuge. You won’t be disappointed with the beauty of this stage, it’s the last one but by no means any less dramatic. You can enjoy a spot of lunch at Paliri before continuing on to Conca for a well earned rest. This stage is a superb jumble of rock and pine and water. From Paliri to Conca you can just reflect on the 200km behind you and you approach the East coast. Holiday ends upon arrival in Conca. Taxi transfers available upon request.
