In reply to Robbo282930:
We've stayed in Camping Olympia before (and am about to stay again next week) and its pretty nice. Three VF's at least within walking distance, but the crags are a drive away, and Cinque Torre is about 20 mins away by car.
Cortina itself is a few K's away, but easily walkable. I'd drive though seeing as parking is like €1 in the town.
Oh there are also two other campsites a bit closer to the town (to the south), and they seemed good when I looked at them as well, just a bit more family-orientated.
