As it's a question for me and not the about the @Climbing-Trail, I'll answer with my personal account.
I'm climbing since 2013, so for roughly 5 years. And the desire to climb still grows day by day. :-) As you described it, it's such a pure sport and so rewarding. If you are interested, you can read about my latest adventure to Croatia (part I and part II, with part III still to come).
Unfortunately, I've never been to Greece to date, but I only heard good things about it! The climbing around Athens and Leonidio must be amazing... And then I heard of Meteora, it must be absolutely stunning... Do you know anything about it by chance? :-)
