Often dubbed the toughest multi-day hike in Europe, the GR20 is a legendary long-distance hiking trail that traverses the rugged spine of Corsica. Known for its steep ascents, rocky terrain, and some almost vertical sections, the GR20 is a challenging trek that requires good physical condition and experience. The trail is divided into 16 stages, but a lot of flexibility is possible and many hikers walk double stages sometimes, or even for the full trek. Did you know that the GR20 can be split into the northern (harder) and southern (slightly easier) halves, each with a very different character?

After a month in the Alps and a week in somewhat more comfortable circumstances, I went to Corsica to hike the north section of the GR20. Even though I was not fully ready to dive into the tent again mentally, I was immediately charmed by this island and the hike. It is truly wild, and there is some sense of togetherness with everyone who is hiking this challenging path. As I was well trained from previous hikes and with a lighter pack (I did not take any food or cooking utensils with me, always eating in the refuges), I found the trek very doable despite its reputation. I doubled one stage to hike 30 km in one day, and took a very nice alternative route on my final day. All in all, my favourite part of this trek was the degree of freedom it offers without giving up on the feeling of utter remoteness.
