Stage 3 of 16 · GR20 North
The Spasimata footbridge, the slabs up to Lac de la Muvrella and the Bocca di Stagnu, before dropping down to the Asco ski resort.

| Waypoint | Altitude | Km |
|---|---|---|
| Refuge de Carrozzu | 1,270 m | 0 km |
| Passerelle de Spasimata | 1,190 m | 0.3 km |
| Bocca di Stagnu | 2,010 m | 3.5 km |
| Haut-Asco | 1,422 m | 5 km |
A few minutes after the hut, the Spasimata suspension bridge crosses the torrent: an iconic GR20 crossing, taken one person at a time. The trail then climbs large sloping slabs, some fitted with chains, up to the small Lac de la Muvrella.
Above it, the Bocca di Stagnu (2,010 m) opens onto the Asco valley. The steep, stony descent reaches the small resort of Haut-Asco (Ascu Stagnu), where you will find the Park hut, a privately run establishment, hot showers and somewhere to stock up.
As the PNRC stresses, there is no water point on this stage, and the water in Lac de la Muvrella is not safe to drink. Set off with at least two liters.
1 water point listed on this stage. Springs can run dry in late summer: ask the hut wardens and treat the water if in doubt.
