This is the schedule followed by many fastpackers: two very steep opening days to Tighjettu, then the long Tighjettu – Manganu crossing (31 km) via Ciottulu di i Mori, Castel di Vergio and Lac de Nino. The last five days range from 18 to 29 km, all the way to Conca.
This is not an itinerary to improvise: it calls for experience of mountain trail running, a minimalist pack and a good pace on the climbs. Book every night on the Park's platform, checking availability hut by hut.

Customise this itineraryTips for this itinerary
- Leave Calenzana at dawn: starting after 11 am is prohibited.
- You can resupply at Castel di Vergio on day 3 and in Vizzavona on day 5.
- Keep some margin: a single thunderstorm or massif closure is enough to throw the whole schedule out.
