Dive Site: Barracuda Lake

About Barracuda Lake

Barracuda Lake presents a truly unique freshwater diving experience in Coron, Palawan, drawing divers with its extraordinary geological features and unusual thermal layers. Situated within towering limestone karsts, this landlocked lake is accessible via a short hike and offers a serene, current-free environment ideal for exploration. The lake is renowned for its distinct thermoclines and haloclines. A layer of fresh water rests atop warmer saltwater, creating fascinating visual distortions and dramatic temperature shifts as you descend. Submerged limestone formations give the underwater landscape an otherworldly appearance, often described as an 'underwater moonscape.' While marine life is less abundant compared to coral reefs, the lake is home to a resident barracuda from which it gets its name, alongside small fish and snails. The primary allure lies in its geological oddities and the unique sensation of diving through varying water temperatures, with temperatures ranging from a comfortable 31°C in the freshwater layer to a hot 38°C in the saltwater. Dive operators in Coron frequently include Barracuda Lake in their itineraries, often combining it with other local sites. Its calm conditions and exceptional visibility make it suitable for a range of divers, from snorkelers to advanced open water divers keen to explore its deeper, warmer zones.

Conditions & Currents

Barracuda Lake is distinguished by its almost complete lack of currents, providing a remarkably calm and serene diving environment. This absence of water movement makes it an excellent site for all diver levels, particularly those less experienced with strong currents. Visibility within the lake is generally excellent, often reaching between 8 and 20 meters, though the halocline layer between the freshwater and saltwater can create temporary visual distortions. A unique aspect of the dive is encountering dramatic thermoclines, where water temperature significantly increases from around 31°C in the freshwater layer to a warm 38°C at approximately 15 meters depth, caused by geothermal vents. Divers should be prepared for these temperature changes, which can be quite pronounced. Entry into the lake typically involves a short swim from the boat to a dock, followed by a somewhat steep descent

Dive profile & how the dive runs

Access to Barracuda Lake begins with a short boat ride from Coron, followed by a swim to a dock and a brief, somewhat steep walk down a path with your gear to the lake's edge. Entry is typically a shore entry. Upon descent, you'll immediately notice the clear freshwater layer, gradually transitioning into a blurry halocline around 10-15 meters as it mixes with saltwater. Below this, the dramatic thermocline creates a noticeable increase in water temperature, reaching up to 38°C. The dive largely consists of exploring the unique limestone rock formations along the walls and bottom, resembling an underwater canyon or moonscape. Divers often follow a route that descends gradually, allowing exploration of the different thermal layers and formations down to a maximum of 35 meters. The dive is usually a relaxed exploration, with no currents to contend with. The safety stop is typically performed in the cooler, shallower freshwater layer, where visibility is excellent.

Underwater photography

Barracuda Lake offers distinct photographic opportunities, primarily focusing on its unique geological features and thermoclines rather than marine life. Wide-angle lenses are ideal for capturing the expansive limestone formations and the surreal underwater landscape, particularly the dramatic walls that plunge into the depths. Experiment with capturing the visible halocline and thermocline layers, which create fascinating blurry effects and visual distortions; these are often best shot with available light or a wide, even light source. While strobes can be useful to illuminate the rock formations, be mindful of backscatter, especially when shooting through the visible water layers. Due to the limited marine life, macro photography is generally not the primary focus, though you might capture small fish or snails on the bottom. Buoyancy control is crucial to avoid disturbing the fine silt on the lakebed and maintain clear shots.

Getting there & logistics

To reach Barracuda Lake, you typically fly into Busuanga Airport (USU) in Coron, Palawan. From there, you'll take a short transfer to Coron Town, the main departure point for dive trips. Most dive operators in Coron offer day trips that include Barracuda Lake, often combined with other local attractions like WWII wrecks or lagoons. A 200 peso ecological fee is usually required upon arrival at the lake, which may be included in your dive package. Trips are generally shore-based, with divers transferring from a boat to a dock and then walking to the lake. Liveaboards focusing on Coron Bay's wrecks may also incorporate Barracuda Lake into their itineraries. No special permits beyond standard dive tour arrangements are usually required for recreational diving.

Safety & environment

Diving Barracuda Lake requires adherence to standard dive safety protocols and an awareness of its unique environment. The nearest recompression chamber is in Puerto Princesa, making immediate evacuation a significant logistical challenge; therefore, comprehensive dive insurance covering emergency medical care and evacuation is strongly advised. Specific hazards at Barracuda Lake include navigating the somewhat steep and uneven path from the dock to the lake's entry point with heavy gear, requiring careful footing. Divers should also be aware of the dramatic thermoclines and haloclines, which can cause temporary visual disorientation and unusual temperature sensations. Always follow your local guide's instructions for routes and depths, and be mindful of your depth and no-decompression limits, especially in the deeper, warmer zones. Hydration is important due to the warmer water temperatures encountered.
