These boulders are in Anogi, Ithaca in the the Greek Ionian islands. They're some of the only worthwhile climbing on the island. There are about 20 odd (seemingly) completely undeveloped limestone boulders and pinnacles (the prominent one is about 30") on private land. I had a scramble about, but scarpered 'cos of dogs. I'm sure the owner would let you climb though, assuming you can speak some Greek, the locals all seemed friendly enough. These boulders are very worthwhile if you're on the island.
