The GR20 in Corsica has the reputation of being the toughest trek in Europe— but you can make it a tad bit easier if you hike just the northern portion of it! Over the course of 10 days, you will hike independently and take it just as easy or as tough as you’d like to. Your guiding service will arrange accommodation and most meals for you, and luggage transfer as well whenever possible—making the trek a lot easier as you don’t have to carry your luggage every day, all day. Get to know the challenging Corsican mountains, learn about the way of life in the mountains, and marvel at the spectacular scenery and wildlife of this unique island! Your self-guided adventure starts in Calvi and ends in Vizzavona.

The GR20 in Corsica is regarded by many as the hardest trek in Europe. It’s a very tough trek with long walking days in succession, meaning that you must be very fit and already have experience with high mountain hiking over several days. There’s also a lot of scrambling and on occasion you will need to use fixed chains and ladders, so it’s not suitable for those with vertigo. Being able to read and follow map instructions is also a must.
That being said, a great thing about this adventure is that you can either choose to do the full GR20, the North or the South Portion!
In general, keep in mind that the GR20 is a very remote trek, making it difficult to “sit out” a day if you’re feeling tired. To see what you can expect, you have a day-by-day distance and duration breakdown in the itinerary—all days are long, so make sure you’re ready for a week or two of consecutive long and challenging days.
Keep in mind that you’ll come across numerous large drops, so you have to be sure that you’re not going to make a clumsy slip. Some ascents are very long, some descents very steep, so that’s something to consider if you have sore knees. Walking poles come in very handy on the GR20, as they reduce the shock on your legs.
Would you feel more comfortable having a professional mountain guide by your side? This guided GR20 trekking tour might be the top choice then!
