Discover Cozumel’s underwater world at night with a unique Sea Trek experience. Walk on the ocean floor, see nocturnal marine life, and capture lasting memories.
Travelers seeking an extraordinary way to experience Cozumel’s vibrant marine environment might find the Sea Trek Underwater Night Dive a captivating option. It’s a blend of adventure, curiosity, and a sprinkle of the surreal — walking on the sea floor after sunset, breathing normally through a special helmet, and spotting marine life that emerges after dark.
What makes this experience appealing? Firstly, the novelty of walking on the ocean floor at night creates a sense of stepping into a secret world. Secondly, the chance to witness nocturnal sea creatures and night-blooming coral offers a rare glimpse into a different side of marine life. However, an important consideration is that this activity is relatively short at just two hours, so if you’re craving a full day of underwater exploration, it might leave you wanting more.
This tour is ideal for travelers who enjoy unique, manageable adventures with a bit of a thrill — especially those new to underwater activities or looking for a fun, safe way to explore marine life after dark. It’s also perfect for families or groups seeking a memorable experience that doesn’t require diving certification.


Location & Accessibility
The tour takes place inside Jeanie’s Beach Club in historic downtown Cozumel — a convenient spot for travelers staying nearby or arriving via cruise port. You simply show up, and a Sea Trek representative greets you — no complicated transportation or logistics. This ease of access is a plus, especially if you’re tight on time or unfamiliar with local transportation.
The Experience: What to Expect
After a quick safety briefing, you’ll don the Sea Trek helmet, a sturdy device that allows you to breathe normally underwater. Unlike traditional scuba gear, this helmet provides a pressurized environment for your head, so you don’t need to worry about equalizing or managing tanks. It’s a fill-in for those who might be hesitant to dive but still want to enjoy the ocean’s wonders.
You’ll descend the ladder to the ocean floor, where you can walk freely — no swimming or diving skills required. The water here is typically calm, giving you confidence to explore at your own pace. As you stroll, you’ll notice nocturnal marine life such as fish emerging after dark, and night-blooming coral that opens up under the moonlight or artificial underwater lights.
The Marine Environment at Night
The underwater landscape transforms once the sun sets. Marine creatures such as crabs, octopuses, or small fish are more active, and some might even glow with bioluminescence if conditions are right. Though not guaranteed, the possibility adds an element of magic to the experience. The use of underwater lights helps illuminate this hidden world, making your walk both safe and visually fascinating.
Photographs & Memories
A souvenir photo is included, giving you a tangible keepsake of your night adventure. Many reviewers mention how this shot captures the magic of the moment — standing in the dark, illuminated by lights, with the ocean revealing its secret life around you.

Cost & Value
At $79 per person, this activity offers a reasonably priced way to do something quite different in Cozumel.

Inclusions & Amenities

People who enjoy nighttime activities, or are curious about marine life that’s active after dark, will find this especially rewarding. However, if your idea of water fun involves hours of diving, snorkeling, or a more extensive marine tour, you might find this a bit too brief.

Many reviews highlight the ease and safety of the activity, noting that “the helmets are comfortable and easy to breathe through,” making it accessible even for those without previous underwater experience. Others appreciated the personalized attention due to small group size. Several mention the spectacular sights of nocturnal marine life as a highlight, with comments like “seeing the ocean come alive at night was surreal.”
