This was fun and exciting. However, be aware of the jellyfish . One lady did get stung while swimming. This would have been better without the jellyfish. Guide was knowledgeable and really nice!More

The jelly fish are active in the summer months due to slightly warmer water temperatures. However, they are very rare in the winter months. Certain operators like "George's Watersports" offer full body wet suits, dive gloves and dive shoes, meaning that it is not possible...More

The concentration of the plankton in the Bio Bay fluctuates from week to week, meaning that you may have been unlucky and had a night which wasn't as good as usual. Certain operators like George's Watersports use full body wet suits, dive gloves and dive...More

Must go with George's Watersports. The difference is unlike other kayak, stand up paddle board or boat tours, with George's you are in the water with masks and snorkels. It is totally amazing the effects of the bioluminescent dinoflagellates. Must do tour while in Cayman

The concentration of the plankton in the Bio Bay can fluctuate from week to week. The visibility of the bioluminescence is good 95% of the time. It is also much better when viewed with a mask in the water.

You could wear a life vest but does help it you can swim in top of water. You cannot put feet on bottom due to Jelly fish and plant life. Water is shallow but you cannot walk in it. You also don’t have to get in the water... More
