Stage 12 of 16 · GR20 South
A day of windswept ridges between two seas, with no shelter: set off with a good supply of water.

| Waypoint | Altitude | Km |
|---|---|---|
| Refuge de Prati | 1,820 m | 0 km |
| Barreaux de la Punta della Capella | 1,950 m | 1.5 km |
| Refuge d'Usciolu | 1,750 m | 10.9 km |
For almost the whole day you follow the ridgeline, with views over both sides of the island. The trail crosses rock bands fitted with metal rungs below the Punta della Capella, then strings together boulder fields and balcony sections.
After a descent to the Bocca di Laparo, a final climb leads to the Usciolu hut, tucked just below the ridge. The stage is exposed: no shelter in a thunderstorm, and the ridges are often windy.
The PNRC warns that this stage is short of water in July and August. Set off with at least two litres and refill at every opportunity.
1 water point listed on this stage and 1 tricky section (chains, ladders, exposed steps). Springs can run dry in late summer: ask the hut wardens and treat the water if in doubt.
| Km | Point | Type | Altitude |
|---|---|---|---|
| 1.5 km | Barreaux de la Punta della Capella | Tricky section | 1,950 m |
| 5.9 km | Source d'Acques Suprane | Water point | 1,414 m |
