The guides are awesome! My wife was so afraid of the ocean and going in they were patient, funny and were attentive to her above water and below.

Excellent service by the entire crew. There were several of us who were abit nervous about diving down in the water. Everyone had an experienced diver throughout the entire activity to ensure our safety and guide us down to see 👀 the sealife below. You could go snorkeling while you waited for your parties turn to go down. The crew members were all professional, kind and friendly people. Highly recommend. Special thanks to Finn, Boom and Uncle for making this an awesome experience.
