Funny, I've been to Bulgaria a number of times since 1990 with the last time being summer 2010. I love the place away from the tourist towns that is.
No comment on the climbing as I have never been but I would suggest that there are plenty of quality places to go. The entire country is mountainous, colder than the UK in winter, bigger mountains and more snowfall for longer than we get......There will be places to climb. I would suggest getting yourself over there and trying to link up with the locals as I also have never found a guide book or any decent web advice when I have searched.
The bulgarian mountains are higher, wilder and more remote with less infrastructure than the UK Hills so you may need to walk lond distances. The skiing on the iother hand is acceptable...just like the UK can be good or bad but its better on more days of the year than any UK ski destination. I have skied Bansko and Borovets.
