In reply to mouseliveson:
I like different crags for different reasons, and of course the time of year makes a big difference due to the need to either hunt out or avoid the sun, what time of year are you going?
My overall favourite is probably Spartacus/Spartan Wall for the sheer range of quality routes at all grades, I'm also a fan of longer routes which helps here.
Kalydna/Stankill/Ivory Tower is great if you want a quiet climb within walking distance of Massouri.
The Beach is good for hot days as it predictably has it's own beach (which you may have to share with goats) so as the sun comes round you can ditch the climbing and go for a dip.
E.T is quality over quantity, not many routes but they are great. The walk in is a killer though so try not to get a project up here...
I've not been to a crag that I would suggest you avoid really, although I've certainly not visited them all. If you really must go to Poets, then don't do it on day 1 as it will destroy your skin.
Yes, Odyssey is as polished as they say, although there are still quality routes there.
The Grotta is a must if you have never been, Ivi or DNA are good pint-sized tasters of the bigger cave routes, if you can get past the queues.
The best thing we did on a rest day was to drive over to Vathi and hire kayaks. Take your shoes for the small DWS cave or just paddle out to sea, it's a beautiful area.
Hope that helps!
