Great Experience
419hillaryw, October 2026
What a wonderful experience the Sea Trek was! Katie greeted us warmly and gave great instructions at the top and let us know what to expect down below. Andres was incredibly helpful and funny getting us into our helmets. And J-Mike was a wealth of unspoken knowledge under the water, allowing us to experience the sea life first hand and taking all sorts of pictures for us!
Thank you to all three for making this so much fun!!!

Omar the sea lion is the man
Chrisbecklaw, October 2026
We had an excellent time. Katie, J-Mike, and Andres were awesome. They explained everything well and we got to see some neat fish. We fed the lorikeets and the highlight was getting to see Omar the Sea Lion perform. We highly recommend this excursion.

We had a wonderful time. We only wished it could've been longer! We particularly liked when we could touch or hold the sea creatures.
