Making the GR20 in 5 days
To complete this trail within these deadlines, you will leave with a lighter bag and a smaller list of equipment. You will have to rely on shelters to refuel. Here is an example of cutting to make the GR20 in 5 days.
A result of a step per day, you put 16 days to make the GR20. This hiking trail between Conca and Calenzana you will discover the Corsican mountains from different angles: rocky terrain (dry and very technical in the north) but also parts greener and rolling (in the south).
Depending on the season, you may have to face the harshness of a day of walking in the sun, storms and fog or the freshness of a shower water source. But this is only a small price to pay for you marvel at the sunsets, stunning views of the sea, the passages of ridges and collars etc.. Small price to pay just to spend an unforgettable holiday.
It is advisable to make the GR20 before June because the shelters are not kept and trails may still be snow in places. It is not recommended to do so even after the end of August because some sources may be tarries.
