Hi Gareth,
Just got back from Meteora, the climbing was great, no restrictions that I could see and a reasonable number of climbers about.
The guidebooks are quite difficult to understand at first, there's two volumes, the first has mostly the classics, and the second has the harder routes in between. There's also a few routes in the Rock Climbing in Greece select guide, mostly the sport bolted routes.
Some of the routes we did had big run outs on the easier climbing, quite scary at times. I pulled one stone out and landed on the belay.
The ambience is fantastic and even on the easier routes the exposure is impressive.
We split our time between here and Pyli, a sport crag about 45 mins drive away, which was also great. A good contrast to Meteora, steep tufa climbing.
Have a good time and drop me a message if you want any more info.
Dan
