"It was a lot of fun and there's something for everyone, I'd say. At least for anyone with a bit of athleticism. In my opinion, even the initial challenges are manageable on the beginner's tour :) Our guides were super friendly, relaxed, and explained everything well. It's also good when it's nice and warm, as I started to feel a bit cold after three hours even in my wetsuit. Renting wetsuits, neoprene socks, and shoes is definitely worth it – it costs five euros."
