Typical Dive Profile
Here's what you can expect during a typical dive at Nassimo Thila:
Descent to Thila
The dive begins with a controlled descent to the top of the thila at around 12-15 meters. This allows divers to orient themselves to the pinnacle's structure and plan their exploration route based on current conditions.

Deep Section
The deeper sections of the thila often feature larger marine life including sharks and rays. Divers typically spend limited time at these depths before ascending to shallower areas to extend bottom time.
Mid-Depth Exploration
The mid-depth areas offer excellent coral coverage and abundant fish life. Divers often circle the thila at this depth, exploring different sides of the pinnacle and observing how marine life varies with current exposure.
Top Plateau
The dive typically concludes with exploration of the thila's top plateau, which features vibrant hard coral gardens and abundant reef fish. This shallower depth allows for extended observation time and a gradual ascent.
Safety Stop & Ascent
Divers perform their safety stop while continuing to observe marine life in the shallower areas of the thila or in the blue water above the pinnacle, depending on current conditions.
Thila Diving Safety Guidelines
While Nassimo Thila offers incredible diving experiences, proper safety protocols are essential for enjoyable and safe underwater exploration of this pinnacle.
Current Assessment
Always assess current conditions before diving. Currents can vary around different sides of the thila and change during the dive. Plan your route to work with currents rather than against them.
Buoyancy Control
Maintain excellent buoyancy control, especially when exploring caves and overhangs. Poor buoyancy can damage delicate coral formations and create hazardous situations in confined spaces.
Navigation Awareness
The complex structure of the thila can make navigation challenging. Maintain awareness of your position relative to the pinnacle and use natural features as navigation references.
Depth and Time Management
The varied depth profile of the thila requires careful monitoring of depth and dive time. Plan your dive to start deep and gradually work shallower to maximize bottom time safely.
Buddy System
Maintain visual contact with your buddy, especially when exploring caves and overhangs. The complex topography can make it easy to become separated if not vigilant.
Cave Safety
When exploring caves and swim-throughs, always ensure there is a visible exit and sufficient space for comfortable passage. Never enter confined spaces without proper training and equipment.
