Do I have to be a good swimmer?
It doesn't matter if you are a particularly fast swimmer or not. All we request is that you are confident in water and can swim.

Swimming with fins and a snorkel can take a little practice if never done before but by the end of your first session they'll become fairly natural to use.

Your underwater ability will improve with time. If you prefer, for your first few sessions you can simply float on the surface following play and whenever you're ready - dive down and have a go!
