In reply to timmyhobby:
I've tried climbing at kefalonia and The nearby Ithaca. Ithaca was generally on better quality rock but still nothing to get too excited about. More for a fun bit of dws and traversing on your hols.
Ithaca did have a nice boulder inland behind vathy (the capital) but it'd be a fair way to go for a couple of boulder problems.
Tbh if it's climbing you're going for, you really need to be going to that other Greek island
