Tip for hiking experts and summiteers:
Medium: Passo Giau and Casera Mondeval di Sora to Rifugio Città di Fiume – from Rifugio Averau follow forest road 464, then turn off and take path 452 which runs along the foot of Nuvolau and later descends to Passo Giau (2236 m). Follow the road briefly to the east and then cross it. Now follow trail 436 to Forcella Giau (2373 m), continue below the rock walls of the Lastoni and above Lago delle Baste (2281 m). Then we recommend a detour to Casera Mondeval di Sora (2158 m), where an archaeological site from the Mesolithic period is located nearby. Continue first to the southeast and later to the north, following path 466 to the Rifugio Croda da Lago.
For experts with equipment: Via Ferrata Ra Gusella – the steep descent begins directly from the Rifugio Nuvolau along path 438/Via Ferrata Ra Gusella. Via ferrata equipment is mandatory. The path joins trail 443 and shortly afterwards path 452, which leads to Passo Giau. From here on continue as in the previous tip.
