Great experience! Can highly recommend Cayman Kayaks. From start to finish. Booking was seamless. Staff were attentive and extremely knowledgeable. Josh and Tom are brilliant. We did the boat tour of the bioluminescent. Best experience! Thank you Cayman Kayaks!


This was by far one of the coolest tours I've taken over many visits to various sites in the Caribbean. We chose the electric boat. It was custom built for night time tours in Grand Cayman's Bio Bay. It is perfectly suited for stargazing from the top deck, and most importantly, allowing passengers to experience the bioluminescence from a specially-designed seating area on the lower deck. This seating puts you very close to the surface of the water, so you can dangle your feet in and reach easily with hands, without having to swim in the water. They also have the ability to block out ambient light from homes on the water's edge, thereby enhancing the bioluminescent effect.

Additional Information

What is Bioluminescence?
On land, fireflies are a good example of what it’s like. Bioluminescence is defined as “Life Emitting Light.” It is a common occurrence in the sea. However, to find an area with high concentrations of it on a regular basis is rare and something not to be missed. Tiny microorganisms called ‘Pyrodinium Bahamanse’ are responsible for this captivating display. When at rest, they appear to sparkle, but when disturbed they release more light to be seen. Come experience it for yourself. The bioluminescence is best seen on the darkest nights of the month.

Is It Safe to Swin?
Guests are encouraged not to swim to prevent being stung by jellyfish or fouling the water. Swimmers should wash off all lotions, bug repellents, hair conditioners and deodorants prior to the tour. The ecosystem here is fragile!

Tours & Times
Park in the Rum Point parking lot for free. Then walk to the far left of the Rum Point Club when facing the water. Look for kayak trailers parked on the roadside. Tours start at 7.30pm and 9.30pm. Please arrive 10 minutes early. Tours last 1.5 hours.

Sky Show
A laser point show of the night sky is given when conditions allow. In the winter months Orion’s Belt, Taurus and Polaris are a common sighting. In the early summer the Southern Cross comes out for a special treat. The Big Dipper, Little Dipper, Scorpio and The Milky Way can be seen throughout the summer months.
