Great experience

The guides and crew members of Seafarers Adventures were very pleasant and helpful. The bioluminescence was amazing as was starfish point. I would go with this company again.

Disappointed

The boat ride and crew were excellent. Star fish point was great. When we reached the bioluminescent area, it was dark and we were encouraged to swim under the boat. What they failed to mention is that there is nothing to grab onto under either side of the boat in the instance you have an emergency or just need to take a breath. Even though they offered life vests before entering the water, they need to be more specific in regards to what you may experience when swimming under the boat. I also feel that the bioluminescence is a little over hyped and not worth the money due to the fact that there is very little glow in the water. Neat I guess but would never do it again and won’t recommend it.

A must do when visiting Grand Cayman!

This was a great trip, and I would recommend it to anyone! This is only one of 5 Bioluminescent sites in the world, so truly an activity that few get to enjoy. Imagine feeling like a super hero while swimming in the water whilst omitting your super power glow. Stopping by Starfish Point was also a big plus. The only down side to this tour is the lack of time spent at each site.

Sparkly Agua!!! 💧✨

Pepe was amazing and funny! He did a good job keeping everyone safe and still making sure we had fun. The water was gorgeous! The bioluminescent plankton made the water look sparkly. We (my aunt and my grandmother) loved it! Highly recommend it!!
