GR20 , Calenzana - Conca, the travers of Corsica, 200 km, two weeks
You've hit on a very popular walk: the GR20. This trail follows the high ridges of mountainous Corsica, an astounding wild and beautiful landscape, dramatically changing from day to day. The GR20 is rewarding and enjoys universal admiration.
The trail is said to be the hardest of the Grand Randonnées. Looking on the map you will be surprised why you need two weeks to cover this small distance. The hardships are many: steep, often smooth plates, tricky in wet weather. Other sections need the help of your hands. Whenever necessary, you will find cables. Another problem is that you won't find many shops. Actually, if you don't like to descent to villages for provisions, you have only one shop halfway, in Vizzavona. This is also the first road you cross in one week time! Therefore, you have to carry food for a week.
Water in late summer can be difficult to find. You must take enough bottles or whatever to carry your water supply for a day.
The weather is probably best in spring, but you will have some patches of snow. From july to september thunderstorms develop in late afternoon. And it is hot! October is more calm, less hikers, but also dry.
One point on the downside must be noted here: the shamefully ill-conditioned facilities. Maybe you don't mind; fine for you. Camping or bivouac is forbidden anywhere but near the "huts" (sometimes "shack" is a better word) and there you will hardly find a place to pitch your tent but you will still have to pay. There is almost no food in the huts, often no meals, frequently no light, maybe one gas-burner for the entire overcrowded hut. We do not know if the situation has improved the last years. From 2009 onwards a reservation system has been introduced, also for camping. This is barely a solution for the bad welcome you get anyhow.

- Positive demanding trail.....wild camped often, found that once it got late the crowds disappeared and I had the route to myself.....really hot but had streams and pools to cool off in
- Negative they were changing the rules the year I went and you now are supposed to sign in with the rangers your intent to walk and give a rough itinerary, you are also supposed to pre book huts (though the hut owners do not like or want this system). Wild camping is technically not allowed, but I had no problems. In short too many rules now I walk to get away from all that.....still a great walk though
- Michael July 2012
- Rate 10
- Positive The GR20 is an excellent experience and lives up to it's reputation of being the hardest Trail in Europe. The water is crystal clear and clean enough to drink straight from the source. The locals were amazing and greeted you like one of the family. The Refuges were well kept, all facilities in working order in a healthy, clean and tidy environment. The Views were needless to say, ... Spectacular.
- Negative Took me 4 weeks to recover my knee caps, though this is more about my not being physically prepared enough for the venture. You really need to be physically fit and capable of ascending and descending over rocky terrain all day long with a back pack on.

- Rate 10
- Positive Technical, demanding hike. many different landscapes. Tough hike!
- Negative very expensive to buy food at the refuges.
- Henk Nouws October 2002
- Rate 9
- Positive This trail lives up to its promise. The mountains are rugged, but still this is a walking trail. In places you need your hands, and elsewhere there may be rather exposed and slippery rock faces. It's a delight.
- Negative Due to it's popularity, too many people want to walk this trail, and the facilities are not in line with this. The huts are terrible and overcrowded - even in october - and camping facilities are even worse, if they exist at all.
