Key Dive Site Facts
Dive Site Overview
Opened in August 2018, K-26 quickly established itself as Asia's deepest diving pool, surpassing Taiwan's Divecube. The facility was designed to cater to a broad spectrum of dive training, from foundational PADI Open Water skills to more advanced certifications like PADI Rescue Diver, Sidemount Diver, and Freediver.
Pool architecture incorporates stepped depth sections, progressing through shallow zones suitable for initial training and mid-range platforms. These shallower sections lead toward the greater depths. Divers can hone their buoyancy navigating a wreck-like construction with swim-throughs, and explore an air pocket.
A carefully managed environment means divers can focus on skill acquisition without open water challenges, such as sharp natural edges or sediment disturbance. Viewing panels in the lobby provide a unique perspective for spectators, observing divers explore the depths.
Best Time to Dive
Diving conditions within K-26 remain consistent year-round due to its indoor nature, ensuring a warm water temperature of approximately 29-30°C (84-86°F). Such a stable aquatic environment makes external climate factors less critical for diver comfort. However, considering surface conditions, periods from January to April and October to December generally present more favorable air temperatures outside the facility. Air temperatures during these times range from -3.03°C (26.5°F) in January to 14.47°C (58°F) in October. Rainfall is minimal during cooler months, averaging between 0.46mm (0.02 inches) in January and 2.73mm (0.11 inches) in April. While peak summer months see higher air temperatures and increased rain, they do not impact the underwater experience. Weekdays are often quieter, sometimes allowing dives without prior reservation if arriving between 8 AM and 5 PM.

Dive Experience & Conditions
K-26's structure includes stepped depths, creating progressive training zones from its shallowest platforms up to 10 meters (33 feet). Water temperatures are consistently warm, maintained at an average of 29-30°C (84-86°F), facilitating comfortable, extended training sessions. For those seeking the full challenge, its deepest section descends to 26 meters (85 feet), forming a vertical tunnel wide enough for multiple divers simultaneously, including freedivers. Divers explore artificial structures, including a wreck-like section for buoyancy practice and swim-throughs, as well as an air pocket. Lightly chlorinated water, characteristic of a training pool, provides excellent visibility free from natural currents or surge.
Dive Difficulty & Safety Guidelines
Understanding diver skill levels is crucial for an optimal experience at K-26. Divers must either be certified and dive with a buddy or arrange for an instructor-guided dive. This site provides a controlled, hazard-minimizing environment, ideal for practicing various dive skills without the complexities of open water. While the lack of natural marine life eliminates certain environmental risks, divers should remain aware of their surroundings, particularly in deeper sections where exhalations from SCUBA divers can create many bubbles that might affect freedivers. Standard safety protocols, including equipment checks and air monitoring, are always essential. Onsite training, equipment rentals, and dedicated staff support all dive activities.
