After asking about this at the end of last year (sorry it doesn't seem to let me reply to the original thread)...

I went to Kamchatka last month
Absolutely stunning place, in terms of climbing not technical at all but I guess that is a function of how volcanoes are formed, some great days out and the volcanoes are very varied.
Would highly recommend a trip to anyone thinking of that part of the world or looking for a bit something different. I think the logistics, right from visa to transport and driving are quite difficult to organise without a local agent though
I have put a few pics on my photo gallery if anyone is interested and have many more
Only downside (apart from mosquitoes) was that I didn't see any bears
