If you’re a certified diver heading to Cozumel, chances are you’re already captivated by its world-class reefs and vibrant marine life. This tour, offered by Cha Cha Cha Dive Shop, promises an exciting journey into the ocean’s dark side—literally—as the sun sets and the underwater world comes alive in a different way.
What sets this experience apart? First, we love the sight of bioluminescence, the mesmerizing glow created by tiny marine creatures that light up the water like a starry sky beneath the waves. Second, the small group size of just six participants ensures personalized attention and a more intimate adventure.
However, a word of caution: since night diving demands extra caution and skill, you must have completed a two-tank dive recently to participate. This ensures you’re ready for the challenges of diving in the dark.
This tour is perfect for certified divers who crave a fresh perspective on familiar reefs and aren’t squeamish about the dark. It’s equally suited for those looking to tick off a bucket list item or just experience something genuinely different during their Cozumel trip.

An Overview of the Experience

This tour is designed for those who already hold a diving certification and are comfortable in the water. It runs about four hours, usually starting in the afternoon, to catch the sunset and follow into the night. The meeting point is the Marina Asipona, conveniently located near the pharmacy, where your guide will find you.
You’ll begin with a brief safety and equipment review, then gear up for what’s likely to be a very memorable twilight dive. As the sun dips below the horizon, you’ll descend into the water, where the colors of the reef shift dramatically, and the evening’s quiet takes over the bustling daytime scenes.
Once submerged, the environment changes. You’re not just looking at the reef as you would during the day; instead, you’ll notice marine creatures that are active only at night, such as certain fish, crustaceans, and the magical bioluminescent organisms that make everything shimmer. Many reviewers mention how stunning the bioluminescent effect is—some compare it to floating in a starry sky, which is hard to forget.
Following the twilight dive, you’ll come back to the surface to enjoy some drinks and share stories. Then, after a short break, the night dive begins. With specialized gear, including an underwater lamp (which costs $15 USD per person if you choose to rent it), you’ll explore the reef under a starlit sky, with illuminated marine life guiding your way.
