Tours

Bioluminescence Tour
Start with a cruise over to Starfish Point for sunset and starfish viewing, then get educated on the upside-down jellyfish before going into bio bay to experience this phenomenon (swimming optional) of seeing the bioluminescence, something that only a few places in the world can offer.

Private Charters
Capt. Marvin's also offers you the option of a private charter. We have several boats of varying sizes that can accommodate groups of all sizes for private stingray/snorkel tours, fishing charters, or combinations of fishing and snorkeling.

Memorable Nighttime Adventure
Bioluminescent bay tours typically take place after sunset, adding an element of adventure and mystery to the experience. Whether you're kayaking or swimming in the bioluminescent waters, exploring the bay under the cover of darkness enhances the sense of excitement and wonder.

Stunning Visuals
The bioluminescent glow created by the dinoflagellates illuminates the water with a mesmerizing blue-green light, creating a surreal and otherworldly ambiance. It's like swimming or kayaking through a sea of stars, making for stunning visuals and photo opportunities.

Interactive Experience
Unlike many natural attractions, experiencing a bioluminescent bay is a truly interactive experience. As you move through the water, every paddle stroke or movement creates a dazzling display of light, allowing you to actively participate in the magic of bioluminescence.

Natural Phenomenon
Bioluminescent bays are rare and magical natural phenomena where microorganisms called dinoflagellates emit light when disturbed. Witnessing this ethereal glow in the water is a unique and unforgettable experience that offers a glimpse into the wonders of the natural world.
Explore Starfish Point And Bio Bay With Captain Marvin's
Our tour of Grand Cayman's most popular phenomenon starts at Starfish Point, where you'll have time to explore the area at sunset and learn all about the upside-down jellyfish that call this spot home. Following that, we will proceed to Bio Bay, where we'll adorn you with the necessary snorkel gear to spend some time snorkeling with the colorful fish before the party starts!
Swimming and snorkeling are always optional for guests, but it's an experience, unlike anything you'll find anywhere else in the world to hop in the water with these tiny microorganisms as they light up the crystal-clear waters of Grand Cayman. Our tours are always family-friendly and guides are more than happy to help little ones get accustomed to their snorkel equipment, so you can enjoy the moment just as much as they will.
