Picture yourself floating in the open ocean at night, far from the familiar reefs and sandy slopes. Beneath you, the water seems endless, with no visible bottom, and all around, the deep holds mysteries that most divers never get to see. This is blackwater diving—an exciting, otherworldly experience that reveals the hidden creatures of the ocean’s depths.

At Siladen Resort & Spa, located in the heart of Bunaken Marine Park, our blackwater dives offer a rare opportunity to witness marine life that ascends from the deep during the night, all while being guided by experienced instructors. But before we dive in, let’s take a closer look at the fascinating history behind this unique type of dive.

A Brief History of Blackwater Diving

The concept of blackwater diving first emerged in Hawaii in the late 1990s, where adventurous divers sought a new way to observe marine life that typically stays far below the surface during the day. The idea was simple yet daring: dive over deep, open water at night, suspend lights from the surface, and see what creatures would rise from the depths.

What they discovered was remarkable. From larval stages of fish and invertebrates to rarely seen jelly-like creatures, blackwater diving quickly became a favorite among divers eager to explore the ocean’s mysterious nighttime migrations. The original goal was to observe the vertical migration—the largest animal migration on the planet, where millions of creatures travel from the deep toward the surface under the cover of darkness to feed.

What Makes Blackwater Diving So Unique?

Blackwater diving is unlike any other night dive. Instead of staying close to the reef, you’re diving in the open ocean over very deep water. Lights suspended from the surface attract marine life from the depths, giving divers a chance to witness creatures in their larval stages. These tiny, often transparent organisms offer a glimpse into the earliest stages of marine life—juvenile fish, squid, shrimp, and other species that look completely different from their adult forms.

The sensation of floating over seemingly infinite water, with nothing but your dive light illuminating the creatures drawn to the surface, is both exhilarating and humbling. Each dive feels like an exploration of the unknown, with new and strange creatures appearing each time.

A Different Kind of Thrill

One of the biggest draws of blackwater diving is the thrill of discovery. Because you’re diving in such deep water, you never know exactly what you’ll see. There’s a sense of mystery and excitement that comes with each dive. Every moment feels like a potential encounter with something new—perhaps a larval octopus, a juvenile fish species, or delicate plankton moving through the dark water.

The experience of blackwater diving is both meditative and exciting. You’re floating in the open ocean, focused entirely on the small creatures illuminated by your light. It’s a chance to witness the ocean’s deep-water ecosystem in action, all while suspended in what feels like the vast unknown.

For the Adventurous Photographer

If you’re into macro photography, blackwater dives offer a chance to capture rare and tiny creatures in ways you won’t find on any other dive. The creatures drawn to the lights are often small, fast-moving, and incredibly unique. Photographing them requires patience, focus, and an eye for detail, but the rewards are worth it. You’ll come away with images of marine life few people ever get to see.

Not Quite Ready for the Deep? Try Bonfire Diving First

While blackwater diving is an incredible experience, we understand that diving over very deep water at night might feel a bit daunting, especially for those who are new to night dives. If you’re curious but not quite ready for blackwater diving, we recommend trying bonfire diving first.

Bonfire dives are conducted closer to the reef, with lights set up near the ocean floor to attract marine life from the surrounding area. These dives are less intimidating but still offer an up-close look at nocturnal creatures, including larvae, squid, and shrimp, all drawn toward the light. It’s a perfect way to get comfortable with night diving while enjoying the incredible diversity of marine life after dark.
