Val Fiorentina - in this valley, surrounded by Pelmo, one could eventually decide to climb the same Pelmo along the N wall, Via Simon Rossi: a classic but strict way, 850 m, V+.
If you stay at Città di Fiume mountain hut, on the contrary, you can go and discovery the south slope of Rocchette (different ways, about 250 m) or of the Lastoni di Formìn. Always from this valley, the road leads to Passo Giàu too, under the already mentioned Gusèla.
