Will do it again

Right out of the marina we had encountered dolphins and experienced more to come. Reef portion was great, plenty to see and good visibility. Crew was extremely informative and always asked if we needed or wanted anything. Would definitely do it again.

Good Sighting

Great crew and good sighting of manta rays. Manta rays seem to be attracted to the blue light more, more plankton perhaps?
