european adventure travel?

I am looking for a company that provides guided adventure tours in Europe. I would like some adventure, climbing, biking, snorkeling, etc but also touring the country. My first coice is Spain, but anything you recommend will be helpful.
Thanks!

Here are some websites to get stared with. There are endless possibilities though...
