Imagine diving beneath the surface as the last traces of sunlight disappear from the horizon. It’s a whole new world at night—one that’s full of surprises, where the day-time dive sites transform into an extraordinary nocturnal realm. Whether you’ve never tried it before or are already hooked, night diving has a way of captivating even the most experienced divers.

At Siladen Resort & Spa, located in the heart of Bunaken Marine Park, our night dives are nothing short of spectacular.

Here are 5 reasons why you’ll fall in love with exploring the underwater world after dark and what makes Bunaken’s night dives so special.

1. After Dark – It’s Transformation Time

If you think the reef is busy during the day, just wait until the sun goes down. At night, Bunaken’s sloping reefs and sandy bottoms come alive with creatures you rarely see in daylight. Nocturnal animals such as cuttlefish, octopus, basket stars and the elusive stargazer emerge to hunt as the silent coral gardens suddenly feel full of life.

It’s these night-time encounters that make night diving so magical. You’ll see cephalopods changing colors in an instant, basket stars unfurling like something from a dream and predators moving stealthily through the water. There’s a sense of witnessing a secret world that only exists after dark.

2. See Dive Sites in a Whole New Light

No matter how many times you’ve dived a site during the day, a night dive transforms it into something completely different. The familiar sloping reefs nearby take on a new mystery in the darkness, with only the beam of your dive light revealing what’s around you.

Without the distraction of broad daylight, you’ll find yourself slowing down, taking in the small details. From spotting tiny shrimps scuttling across the sand to watching a sleeping parrotfish tucked into its mucus cocoon, night diving encourages you to observe the reef in a more intimate way.

And for those who have never experienced the magic of night diving, we offer Night Dive Adventure Dives. With one of our experienced instructors, you’ll learn how to navigate and explore safely in low light, all while discovering the fascinating creatures that come out to play after the sun sets.

3. Bioluminescence: Nature’s Glow Show

One of the most captivating aspects of night diving at Siladen Resort & Spa is the chance to witness the bioluminescent marine life that often goes unnoticed during the day. While it’s not the water itself that glows, certain marine organisms have the incredible ability to emit light when triggered by specific conditions.

During our fluorescence dives, we use specially filtered dive torches designed to reveal the hidden bioluminescence of marine creatures. These filters unveil the glowing patterns of corals, anemones, and other marine life, creating a surreal underwater light show. What was once invisible to the naked eye during the day now it transforms into vibrant colors under the beam of your torch, glowing with neon-like brilliance.

With the right equipment, you’ll see the reef in a way that feels otherworldly—bright blues, greens, and reds shimmering as marine creatures react to the light. It’s a mesmerizing and unforgettable experience, adding a layer of magic to your night dive that can’t be found anywhere else.

4. Try Something Extraordinary: Blackwater & Bonfire Diving

At Siladen Resort & Spa, we don’t just offer regular night dives—we invite you to take your nocturnal diving to the next level with blackwater and bonfire diving.

• Blackwater Diving is a special type of night dive conducted over deep water. Lights are suspended from the surface, attracting tiny creatures in their larval stages—part of the largest vertical migration in the animal kingdom. On a blackwater dive, you’ll have the rare chance to witness these larvae up close, floating like delicate jewels in the dark water. It’s an otherworldly experience that gives you a glimpse into the ocean’s incredible processes.
• Bonfire Diving, in contrast, takes place closer to the reef, where fixed lights attract a variety of marine life. The lights draw in small creatures like squid, shrimp, and fascinating larvae that emerge from their hideouts in the back reef and deeper waters nearby. It’s an incredible opportunity for macro photography, giving you a closer look into the nocturnal world of marine animals that often go unnoticed. The glow of the lights reveals the delicate details and behaviors of these tiny creatures, offering a mesmerizing and unique night diving experience.

For those who prefer to stay closer to the surface, night snorkeling is also an option, giving you a front-row seat to all the action without diving deep.

5. Embrace the Silence of a Night Dive

Night diving isn’t just about the creatures you see—it’s about how the experience makes you feel. Diving at night forces you to slow down, heighten your senses, and truly immerse yourself in the underwater world. With fewer distractions, it’s just you, the ocean, and the gentle movement of marine life.

The peacefulness of night diving is something you can’t fully understand until you’ve experienced it. It’s a chance to connect more deeply with the ocean, to feel part of its rhythms, and to appreciate the quieter, more hidden side of marine life. At Siladen Resort & Spa, diving at night in Bunaken Marine Park offers a rare opportunity to be part of this incredible ecosystem after dark.
