About Sea Thru Kayaks VI
Sea Thru Kayaks VI offers nighttime guided kayak tours of the bioluminescent bay on St. Croix in the US Virgin Islands. Our tours launch from Salt River Marina at nightfall and utilize fully transparent “sea thru” kayaks to provide each guest with a uniquely unobstructed view of the waters around them, allowing each kayak to become fully immersed in the glowing bioluminescent wonder!
Come see for yourself why Sea Thru Kayaks is the only way to fully immerse yourself in the wonders of the water below. After a trip with Sea Thru Kayaks VI, you’ll see St. Croix in a different light!

What is Bioluminescence?
Bioluminescence is the emission of light created by a living organism. In the Salt River Bio Bay, you will experience the light-emitting phenomenon of the single-celled microorganisms called dinoflagellates. As the water is agitated by the passing of your transparent kayak, it will seem as if your entire boat is surrounded by glowing light. Depending upon conditions, the bioluminescence may appear as a cloud of pixie dust, or a starry galaxy racing beneath you!
