It's always like this with water: even if something looks "touristy," it may technically be considered a high-risk activity, and it's best to figure it out in advance. I was looking for information on this very topic and found https://www.globelink.eu/exten....sions/adventure-acti – I liked that underwater activities are highlighted separately and described quite clearly. It seems like the service is focused on reality: people go diving, swimming, trying new things, and they need a clear framework, not guesswork.
