Discover Corsica

The GR20 trail in 13 days

Guided tour. The GR20 crosses the island by following the high mountain range that forms the natural boundary between the two departments of Corsica. From Calvi (north west) to Porto Vecchio (south east), this trek offers fantastic sceneries and a taste of the authentic and traditional life in the mountains. The GR20 is known to be the toughest trek in Europe. But thanks to our logistics, you avoid to bring a heavy rucksack that significantly increases your pleasure to walk.

A stay beyond our expectations... Great organisation and atmosphere. Harder than I imagined, even though I knew the GR20 was not something easy. And a great guide to crown it all !

Thank you and bravo to Couleur Corse / Corsica Discover

After the great trip I would like to give my ratings. I haven’t found the link on your web site so I send it to you. I hope that’s fine.

1. GR20 – South
Guide: Xavier
Date: 05.06. – 10.06.2022
General Rating: Very satisfied
My Comment: I had very much underestimated how tough the walk was. The problem was not the length or the altitude, it definitely was the terrain. However, I learned so much about the technique from Xavier that I got better and fitter every day. Without his instructions I would have never succeeded. Although I was behind my fellow group members (most of them younger than me), he has always given me the courage that he believes in me that I would make it. That way he taught me was fantastic. Often, he let me choose the way and gave options so I could learn to find my own way. This way he made me fit for the North.
In addition, I was a bit surprised that I was the only non-French. Since there was a bit of rest of my French knowledge, the tour was a language course for me too. The first day Xavier talked a bit in English was me but soon noticed that I understood, when he talked slowly and that I preferred French. So, we talked French, but always made sure that I understood when it was important.
He was always there when I needed him, and he let me on my own when it helped me to find my confidence. He couldn’t have done better. Please pass him my deepest thanks!
Apart from the guide, the group was fantastic too. I was fully integrated despite the language issues and that I was behind in walking in the first days. I was never alone or desperate, not one moment.
2. GR20 – North
Guide: Pauline
Date: 11.06. - 17.06.2022
General Rating: Between satisfied and very satisfied
My Comment: Pauline was also very nice and very competent, and she also took very good care of me. She helped me very much and she brought me to the happy end. However, I have the feeling that she underestimated me. In the new group, there were two or three members who were not ahead of me. But, I had the feeling she thought me the far weakest, which I wasn’t. In some situations, she guided me too much, didn’t let me find my own way. However, I was very happy with her. It’s better and safer to underestimate somebody than overestimate them!
With the language, she also noticed that I preferred French slowly spoken and did so, and she also always made sure I understood when it was important. I was very happy with that too.
In the North, the group was too big. We were twelve, which I found was too many. The group often disrupted. That was nobody’s fault, it simply was because of size of the group.
3. General Rating of Couleur Corse:
I was very satisfied with everything! If I ever do it again, I will definitely do it with Couleur Corse again. I would always recommend Couleur Corse to everybody who speaks at least a little bit of French.
I appreciated the fantastic organisation already long before the trip, the very good recommendations for the equipment and the quick and competent reply for any questions.
I also appreciated the fantastic organisation during the trip, the very good supply of food – exactly what the body needed during the walks. I was very pleased that most of the food was local products. I do like the Corsican product, but it’s also good for the local producers and for the environment due to short supply routes.
I was also very pleased seeing all guides (Xavier, Pauline, Paulo) collecting any rubbish they found on the way. They did it without talking or showing, just because they felt it. That’s a very noble gesture. I would like to see that in other parts of the world too!

Since 1994, when I was in Corsica for the first time, I wanted to do the GR20. Now, 28 years later I finally did it. I fulfilled my dream. It was much harder than I ever thought but it also was much more beautiful and breath taking than I ever thought. I’m very proud to have succeeded. I will never forget the wonderful tour as long as I shall live. I want to say thank you to Couleur Corse having made that possible.

My warmest regards,

The GR20 (Sud + Nord) hike was stunning. Well organised (the stays at the refuges/bergeries and the food) and both guides (Paul for Sud and Julien for Nord) were excellent. It is not the easiest of hikes yet very fulfilling.

7.Posted by Eleanor Harvey on 08/02/2023 11:01 AM
Very well organized, our guide was very kind, competent and knowledgeable. The scenery was incredible and I really was able to enjoy it without having to worry about the logistics of the hike. The group I was with was very kind and even though my French isn’t perfect they were very patient. The only thing I would say is there were limited food options for vegetarians at some of the refuges and including a jar of hummus or peanut butter with the snacks would be a nice addition to the snacks in the future. Merci beaucoup!!

Alex was one of the best guides I have ever had the pleasure of trekking with. Really knowledgeable and professional. I was the only non French speaker in the Group and was made to feel very involved.
