Trail running on the GR20 in Corsica! There is no time for picnic or restorative naps, but peaks, streams and mountain passes drain the rapid pace of our steps.

The GR20 is tempting for many people, perhaps too many, given the size and outdated accommodation. But this inconvenience is part of the game. It is a beautiful but demanding trip. Being able to do it and not to try is a sin, but doing it without the right preparation is a big mistake!

Hiking on the GR20 is a choice that involves attraction and respect for nature and the mountains, taste for effort and walk, ability to withstand a precarious comfort  (day and night), enjoying group life and with a sense of solidarity.

I propose you to achieve the GR20 in 7 days. You will be thus deciding to double the efforts that a hiker is able to do on one stage.

The highlights of the trip I propose are the following:

  • The comfort of daily assistance
  • A guide or coach state certified expert in mountains
  • A personalized assessment of the level of participants
  • A circuit for high mountain sports or “trailers”
  • A “light” backpack

This trip is reserved for hikers in excellent physical condition, who practice sports regularly and in an advanced level throughout the year, able to overcome a difficult and fragile ground.

With daily assistance (you will find your support bag every evening), and meals in the refuges in our way, your confort is enhanced.

I invite you to contact me if you are interested in this beautiful adventure. If you want to do a GR20 in less time, it’s possible. Please contact me and we’ll discuss it. I also guide the GR20 South, from Vizzanova to Conca, you can check it out!


Day 1

Bonifatu – Asco

A serious leg-up.  From the forest of Bonifatu through a good path with beautiful slabs of granite we will ascend the  Spasimata valley. After the Muvrella lake, we will cross the Bocca di Stagnu and we will descend to the high  Ascu valley.
Lunch and night at the Ascu Stagnu lodge.
Duration: 5 hours
D +1530m/-680m

Day 2

Asco – Vergio

A technical stage in the high mountains. In the morning, we’ll cross the famous Cirque de la Solitude. It is the most technical passage of the GR20. Chains and ladders allow us to cross the most difficult passages. We will advance in the heart of the highest peaks of the island. The very mineral and tormented scenery is not appeased until the end of the stage, with the approach to the Verghju Pass.
Night at the Castel di Vergio lodge.
Duration: 8 hours
D +1620m/-1610m

Day 3

Vergio – Grotelle

This is a varied and a very esthetic stage. This stage is more bearable and fresh, and will take us to the shores of Ninu Lake, and then to the Camputile plateau. Then, the high mountain reaffirms its rights. We will gain the Capitellu notch, then descend to the Grotelle sheepfold through the lakes variant.
Night in tents at the Grotelle sheepfold.
Duration: 8 hours
D + 1230/-1270m

Day 4

Grotelle – Vizzavona

This is a difficult day. Through the wild Cascade Valley we will find the GR20 at the  Rinosu Pass. We will go through the Petra Piana refuge, and by a spectacular ridge path, we’ll reach the Onda refuge. We’ll still ascend to the Muratellu notch before taking the long descent towards the Vizzavona Pass.
Night in a lodge at Vizzavona.
Duration: 8:30 hours

Duration: 7 hours
D +1200/-1010m

Day 7

Bassetta – Bavella

Last but not least. After crossing the lawns of Cuscionu and ascending the softly shaped Incudine, the tormented figure of the Aiguilles de Bavella appears . Crossing it by the Alpine variant, is a strong moment of the GR. After a final descent we reach the Bavella Pass, the end of our trip in the heart of the corsican mountains.
