Celtic Deep Offshore Expedition

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

Explore the wild waters of Pembrokeshire like never before! A unique, up-close experience with the wildlife and wonders of the natural world that lives below and above the waves of West Wales.

A full day on the waves of the Celtic Deep as you become a floating beacon for some of the most spectacular wildlife. Heading out into deep open water, you’ll be on a search party for some mega marine animals. Taking the trip will give you a chance at meeting (and swimming with!) the oceans apex predator. Sharks comb the waters, with Threshers and Blue Sharks and potentially a rare sighting of the Mako.

Later in the year, whale watching is the order of business. Long finned and Minke Whales can often be found moving through the surf, whilst there’s even a chance to see the spectacular sight of the epic Humpback Whale.


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