Semporna, Sabah
☀️ Kapalai Island
The Floating Paradise & World-Class Muck Diving
Kapalai Island is truly unique within the Semporna archipelago for one reason—it is not actually an island. Instead, Kapalai is a stunning sandbar perched atop the vast Ligitan Reefs. Once a vegetated island, natural erosion has reduced it to a narrow stretch of white sand that fully emerges only during low tide.
Today, Kapalai is renowned for two defining features: its luxurious water village resort built on stilts above the reef, and its reputation as one of the best macro diving destinations in the world. Unlike the dramatic deep walls of Sipadan, Kapalai offers shallow, relaxed, and exceptionally productive muck diving. It is a true underwater photographer’s playground, where rare and unusual marine critters can be discovered on almost every dive.

🧭 Why TDB Semporna Dives Kapalai

-
The “Aquarium” Effect: Shallow, clear waters combined with a high density of fish create the sensation of swimming inside a giant natural aquarium.
-
Accessibility: Kapalai is located very close to Mabul, making it easy to combine Mabul and Kapalai dives into a single, well-paced day package.

📅 Best Time to Dive Kapalai Island
Kapalai is a year-round destination, though conditions vary slightly by season.
April to September (Dry Season): Status: ⭐⭐⭐⭐⭐ Sea conditions are typically glass-calm, which is ideal for macro photographers who need stability to capture fine details. Strong sunlight illuminates the shallow sandy bottom, making the colors of nudibranchs and other small critters stand out vividly.
October to March: Status: ⭐⭐⭐⭐ Winds can occasionally increase during this period, but Kapalai remains naturally protected by the extensive Ligitan Reef system. Even when open-ocean conditions are rough, the shallow
dive sites around the sandbar usually stay calm and diveable.
-
Note on Visibility: Visibility at Kapalai typically ranges from 10 to 20 meters. For macro diving, unlimited visibility is not essential—the focus is on the fascinating marine life right in front of your mask.
🐠 Marine Life & Underwater Highlights

hours. -
Macro Critters: Careful observers can find nudibranchs, blue-ringed octopus, and the striking flamboyant cuttlefish hunting across the sandy seabed.

The Residents: Large green turtles and massive
stingrays (often referred to locally as Jenkins rays) are commonly found resting beneath the wooden wreck structures.

🌍 Famous Dive Sites at Kapalai Island
We operate daily speedboats from the Semporna Jetty. The boat ride takes approximately 45 minutes. We often combine Kapalai with Mabul in a 3-dive day trip, as they are only 10 minutes apart, giving you the best of both reef and muck diving in one day.
Environmental conservation is a priority for TDB Semporna. Kapalai’s reefs are part of a sensitive ecosystem. We practice Strict Neutral Buoyancy and No Touch policies to protect the fragile soft corals and resident critters like the Blue-Ringed Octopus that call these sands home.
Unlike Sipadan, Kapalai does not require a restricted daily permit. This makes it a flexible and guaranteed addition to your Semporna diving itinerary. You can dive here any day of the week, making it an excellent buffer dive while waiting for your Sipadan permit dates.
Absolutely. Because the reef top is just 1 to 3 meters deep, snorkelers get a diver’s view of the marine life. It is common for snorkelers at Kapalai to swim alongside Hawksbill turtles and schools of Batfish right under the resort walkways.
Yes. Kapalai’s Mandarin Valley is one of the most reliable spots in the Semporna region to witness the mating ritual of the Mandarin Fish. This activity usually occurs at sunset. We recommend booking a specific sunset dive with TDB Semporna to witness this rare behavior.
While both are macro havens, the main difference is visibility and lighting. Kapalai typically has clearer water (15m+) compared to Mabul’s silty environment. For photographers, this means better wide-macro shots where you can capture a Frogfish or Nudibranch with a clean, blue-water background.
The Kapalai House Reef is a world-class artificial reef system. Over the years, TDB Semporna has observed these man-made structures—sunken boats and wooden frames—evolve into a thriving ecosystem. It is the best place to see Giant Groupers and resident Green Turtles that have become habituated to divers, allowing for incredible up-close encounters.
As dive technology and training evolve, Kapalai remains the gold standard for PADI Open Water Diver courses. Its white sandy bottom provides high natural reflectivity for excellent visibility, and the lack of surge or current makes it a natural swimming pool. It offers a much higher safety margin for buoyancy practice compared to the silty bottoms of Mabul.
No, Kapalai is technically a sandbar situated on the Ligitan Reefs. There is no natural land above sea level at high tide. The island experience comes from the iconic water village built on stilts. This unique geography makes Diving Semporna at Kapalai a one-of-a-kind experience, as you are diving on a submerged reef plateau in the middle of the Celebes Sea.
