Celtic Deep Islands Odyssey

Ages   16+
Paying adult required
6 hrs Session
Blue Lagoon Water Park

An exploration of the waters around Skomer and Grassholm Islands and the wildlife that calls them home.

Look out for the iconic puffins and curious seals poking their heads above the surf, as you take to the waters, stealthily snorkelling with the guidance of expert instructors.

When not amongst the waves, spend the rest of the session relaxing on the boat, with an eye out for the various birds that take to the sky around the islands, as well as some potential surprises, from pods of dolphins to leaping sunfish!


Please note: We cannot guarantee that you will have sight of all these awesome animals, however, we can guarantee a truly epic adventure.
