In reply to Roberttaylor:
I'm not sure it has an epicentre like you're suggesting. The area is vast compared to Chamonix or Ailefroide and it really depends on what you want in terms of an epicentre. If you are looking for somewhere you can pick up partners that would be totally different to an area with the greatest amount of accessible climbing. Whatever, you will most definitely benefit from having transport to get the most from the area. For me personally, my favourite area is around the Sella Pass, and around Passo Falzarego.
