Adventure Sports Kayaking

Hi, can anyone suggest an active holiday, new or different in Europe – I've done mountain biking, kayaking, etc.
For adventure travel I mean outdoors, "sports", suitable for someone with a reasonable level of fitness. I am not alone in looking for extreme sports – can be considered something peaceful, while interesting! …
Trying Via Ferrata, breathtaking views and a good way to get great exposure in the mountains without having to know how to climb.
