This the nicest sport climbing area with low to mid grade options...
Citta dei Sassi (City of Rocks)
If you could afford a hotel up there at 80eur a night half board then you are sorted. Otherwise, if it's possible to find cheaper accommodation in the surrounding valleys, you could commute by bus to that and various crags other crags. Base options include: Canazei, Arraba , Cortina, Selva, Corvara/Colfosco
The buses aren't very frequent but with careful planning it's possible to get to many crags around Sella Rond and Passo Falzarago for the day.
