The trail consists of two parts. The difficult and rocky northern part, where you will be having to tackle constant steep ascents and plunging descents, it begins in Calenzana and ends in Vizzavona.
The Southern part, which spans from Vizzavona to Conca, is the easier leg of the trail, but not as spectacular as the northern part. You can choose to do either of the two parts or complete the entire hike from Calenzana to Conca.
You can do the trail in either direction, but it is most often done from north to south. If you are looking to avoid the crowds it is suggested that you hike northwards.
The trail, separated into 16 sections, winds its way along the jagged granite spine of Corsica’s mountainous center.
The terrain is rugged, but the trails are well marked with red and white rectangles on rocks, boulders and trees.
Although the trail is well-marked it is still highly recommended that you make use of a map to avoid getting lost.
The amount of time needed to complete the trail can vary considerably from hiker to hiker, but on average it should take hikers between 11-16 days.
When planning your trip, be sure to factor in an extra day or two in case of inclement weather. You may also want to consider a few extra days to enjoy the rich culture and history of the various villages as well as spend time at the beautiful beaches.
Mountain huts known as refuges offer basic accommodation along the route as well as the option to purchase food and drink. These refuges generally consist of one large dormitory that sleeps between 25-50 people.
You may also have the option to sleep in a tent near one of the refuges, this option is also a bit cheaper than staying in the actual refuge. It is recommended that you pack a tent in case any of the refuges are booked so you have a place to sleep.
Wild camping is prohibited so you will need to make sure you set up camp in the vicinity of a refuge. There are also private lodgings along the trail and although they are more comfortable they will also be more expensive.
It is recommended that you visit in late June and early September when most of the refuges are open, the weather is not so hot, and the trails are not so crowded.
Avoid hiking in July and August as this is the most popular time and the trail will be crowded.
