Barracuda Lake

Float peacefully in Barracuda Lake, Coron.

Coron is one of the top destinations for travelers visiting Palawan, Philippines. Nestled amidst the breathtaking landscapes of Coron, Palawan, Barracuda Lake emerges as a captivating wonder for adventure enthusiasts and nature lovers alike.

This famous destination offers a remarkable blend of stunning natural beauty and a distinctive thermocline phenomenon, making it an ideal spot for divers and snorkelers seeking an extraordinary underwater experience. This famous fresh and salt water lake holds a secret that draws in diving enthusiasts from all over the world.


Barracuda Lake is renowned for its mesmerizing thermocline phenomenon, a unique occurrence where the water temperature changes dramatically at different depths. As you descend into the lake, you’ll feel a distinct transition from warm surface water to cooler depths, but then even warmer again. This phenomenon creates a fascinating diving experience, unlike any other, as you navigate through layers of varying temperatures. With that being said, Barracuda Lake offers one of the most unique diving experiences. Occasionally referred to as Luluyuan Lake by locals, its crystal blue waters are hidden between majestic rocky formations.

Prepare to be enchanted by the crystal-clear waters of Barracuda Lake. Its exceptional visibility offers a window into an underwater world filled with awe-inspiring rock formations, submerged trees, and intriguing marine life. The lake’s remarkable clarity allows divers and snorkelers to explore its depths with unparalleled clarity, providing an immersive experience like no other.


Starting out on the surface of the lake, divers, swimmers, and scuba enthusiasts can expect temperatures around 82 degrees Fahrenheit. But as you dive into lake deeper, around 45 to 50 feet down, the temperature of Barracuda lake suddenly changes to just over 100 degrees Fahrenheit (so you don’t need to wear a wet suit as most people’s hot tubs are at 104 degrees).

Since Barracuda Lake is made of both fresh and salt water, the result is this unusual temperature rise. What’s more surprising is that the divers can even distinctly see the thin boundary that separates the two bodies of water.

Barracuda lake is also characterized by an impressive display of limestone formations that rise up on all sides and extend beneath the surface.

Divers flock to Barracuda Lake for its unique geological formations, including jagged limestone cliffs and underwater caves. As you dive deeper, you’ll encounter a submerged rock face and swim-through crevices that add a touch of mystery to your underwater adventure. Keep an eye out for barracudas, snappers, and other marine creatures that call this pristine environment home.


If you get really lucky you may even have a chance to encounter with the only resident barracuda for which the lake was named, who is said to lurk in the shadows of the lake’s thirty-meter cave. Let’s just say, scuba diving Barracuda Lake is a sensory experience you are sure to remember for the rest of your life.

Did you know that when you dive into Barracuda Lake it feels like you’re walking on the moon? You will have a sense of “weightlessness” like you’re floating while exploring the hot or cool depths, a sensational experience (which is largely devoid of flora and fauna).

However, the lake holds yet another shocker: just when the salt watery heat becomes a bit unbearable, the temperature changes back to cool again near the bottom — I know, it might sound and FEEL scary!

Another special feature of the lake is the sand at the very bottom, which has been described as “jelly-like,” “silky,” “airy,” and “silty.” The lake bottom was so light and airy, with one throw you could fill the water with a billowing cloud of its murkiness. It’s apparently good for play, too. And although the barracudas aren’t really around anymore, if you’re lucky, you may still catch a glimpse of one.

Don’t Miss

  • Start your island hopping boat tour early in the morning before 9AM the tourists from joiner or group tours arrive. The entrance to the lake is small, so it can get crowded during peak hours. Best to avoid the crowds is by booking a Coron private boat tour.
  • Chill by the lake and enjoy this piece of paradise surrounded by limestone cliffs.
  • Visitors may snorkel or swim in the lake. If you’re lucky, you might catch a glimpse of the barracudas residing in its waters. The name may sound scary but no need to worry because the barracudas won’t eat you.
  • You may even spot other fishes like rabbit fish, cray fish, catfish, and other sea creatures from the ocean that have found their way through the small openings in the limestone cliff walls.
  • If you are into diving, you will have the chance to experience the changes in water temperature (thermocline) as you go deeper.

  • Follow the rules at all times. Practice caution, especially when swimming without your life vest. The lake is very deep, if you can, do not go on your own or out of sight of your companions or the local guides.
  • If you are planning to swim, just bring what you need. There’s a resting area but it is advised to not leave your things unattended.
