Stage 4

Haut Asco to Tighjettu
5 hours · 8 km · 1269 m gain
You cross the Cirque de la Solitude area on steep, technical terrain - the name tells you what to expect. Plan for about 5 hours; this section demands concentration, good footing, and respect for exposure.
Tighjettu is a refuge in alpine pasture country. The Solitude crossing is often the day walkers remember most - start early and avoid afternoon weather.
