Descripció
Right at the water’s edge, at Illa Mateua, we’ll uncover the glowing underwater world. Did you know that below 200 metres, 75% of all marine organisms produce their own light?
We’ll explore why they do it and what mysteries bioluminescence still holds. And for the brave ones: we’ll end with a dip in the water to feel it first-hand. We’ll share every secret to make the most of it this summer.
Snorkel gear included.
Languages: Catalan(Sundays), English (Thursdays), Spanish.
Private experience available for groups and families.
Suitable for: Recommended age 8+ to follow the talk —younger kids are welcome along. We adapt the explanation to the group. If you’re bringing children, they must be accompanied by a responsible adult at all times. The dip is optional — up to every participant!
