Bioluminescent Bay Tours in completely transparent "sea thru" kayaks

Why choose us?

The difference is CLEAR!


The best bioluminescent light show is beneath your transparent kayak as you are engulfed in millions of light emitting organisms.

Other kayak styles give you a limited view over the sides or a small window.

What is Bioluminescence?

Bioluminescence is the emission of light by a living organism.  In the Salt River Bio Bay, you will experience the light emitting phenomena of the single celled micro organisms called dinoflagellates.  As the water is agitated by the passing of your transparent kayak, it will seem as if your entire boat is engulfed in a light glow, or depending on the conditions, a cloud of pixy dust, or a starry galaxy racing beneath you.

What happens if I don't show up? We require that reservations are canceled by phone call 48 hours prior to the tour, or you will be charged the full tour value on the credit card provided.

Does my wight really matter?  Yes, but only to the kayaks.  Our Sea Thru kayaks are weight limited at 235 lbs per person, and 385 lbs per kayak.  There will be two people per kayak. The wight limits are critical for paddler safety.  When the kayaks are over loaded, they are much more susceptible to sinking.

Can I  use my "high school weight"?  All guest will be weighed in upon arrival, without exceptions.  The kayak weight limits will be adhered to, regardless of what your driver license says you weigh. 

Why can't I wear bug spray?  The deet and other chemicals in bug repellants are harmful to the bioluminescent organisms that we are here to witness. If you are concerned with insects, we recommend you wear long sleeves and pants to limit your skin exposure to biting insects.

What should I wear?  We recommend swimwear or other moisture wicking clothing.  You will likely get wet from ocean spray or water splashing and dripping on you from the paddles. If you are sensitive to bugs we suggest long pants and a long sleeved shirt.  

*No footwear of any kind will be worn in the kayaks.

Can I swim in the bay?  No, unfortunatley we don't allow swimming in the bay.  This is for both for your own safety, and to protect the organisms we are here to see. 

Why is there an age limit  This is an adventure tour with a considerable paddle in each direction.  All children under the age of 13 must have a capable, fit adult in the kayak with them, and children under 8 will not be allowed on the tour.  

What if I have more kids than adults?  All kayaks will seat two people, and each  child must be accompanied by an adult.  If you have more kids than adults, please give us a call to discuss options of paring your child with one of our guides.

What if my party has an odd number of people?  On the day of the tour, it is likely that your un-paired party member will be paired with another guest on the tour, or will be paired with one of our tour guides.

What happens if it rains?  We will commence and continue tours in the rain. Sudden Caribbean rain showers have been known to occur, typically the rain passes quickly, and the tour will resume.  Rain storms do not affect the bioluminescence, and actually add a beautiful rain drop glowing effect. 

What can I bring in the kayak? Guest may bring a plastic bottle of water and a camera on board.  No bags, alcohol, tobacco, or e-cigarettes are allowed.

What happens if I cannot complete the tour?  If you are unable to complete the tour, you will be towed back to shore and charged FULL trip value.  Examples of people who couldn't complete the tour are; people who are intoxicated, under the influence, not physically fit enough to complete the 1.5 mile tour, and people who are too heavy for the kayaks.

Is the tour difficult?  We do consider this an adventure tour.  We launch in paddle powered kayaks, travel 3/4 mile in each direction, and cross the Salt River Bay en route to the bio bay. The difficulty of the paddle across the bay depends upon the current environmental wind and wave conditions.  This is not a race or a contest, and your safety is the highest priority for our guides.  Please consider your own current physical fitness level prior to booking this tour.  If you are not comfortable even walking 1.5 miles, do you think that you would be comfortable paddling that distance?

Does it matter that I cannot swim?  No worries.  All guest will be fitting with, and required to wear, a USCG approved personal flotation device.
