Why go

Barracuda Lake is reached by a short scramble over a limestone ridge from a cove on Coron Island. You climb a wooden ladder and stairs, descend the other side, and find yourself on a little floating platform beside water so clear that it looks like glass poured over grey rock. The cliffs around it rise in steep, broken spires.

Snorkelling here is a quiet experience: there is no reef and few fish, just extraordinary visibility and the feeling of floating in a vast, cool space. But divers come for something even stranger. As you descend, you pass through a sharp change in temperature; the water near the bottom can feel as warm as a bath, and there is a shimmering blur where fresh water meets salt.

I am not a diver, so I floated and watched others drop into the depths, their bubbles rising past my mask. Even from the surface, the scale and stillness of the lake made me hold my breath longer than I meant to.

The story

The lake is named after a barracuda that divers reportedly encountered here, though nobody seems sure whether it was a single legendary fish or a few over the years. It’s an appealing story: a fierce sea predator somehow living in an enclosed lake, as if it had climbed over the cliff to get there.

The lake’s layered water is created by geology. Rain-fed fresh water sits on top, while seawater seeps in through the porous limestone below. Between them is a halocline, where salinity changes abruptly, and a thermocline, where the temperature rises sharply. Divers report temperatures approaching 38°C at depth, likely warmed by geothermal heat.

Like Kayangan, Barracuda Lake lies within the Tagbanua ancestral domain on Coron Island. The community allows access here but has closed many other lakes on the island, which they consider sacred or simply prefer to protect from the boats that line up in the coves on busy days.

Getting there

Barracuda Lake is often included on standard Coron Island tours, alongside Kayangan and Twin Lagoon. Divers should book with a licensed dive centre in Coron town, which will handle the boat and fees. The climb from the boat to the lake takes about ten minutes over steps and a ladder.

Arrive early or late in the day if you can; at midday the platform gets crowded and the calm of the lake is harder to find.

A suggested plan

1. 8:30Boat from Coron town to the cove below Barracuda Lake.
2. 9:15Climb the ridge and descend to the floating platform.
3. 9:30Snorkel or dive, letting your eyes adjust to the strange clarity.
4. 11:00Return to the boat and continue to nearby reefs or lagoons.
5. 12:30Lunch on a beach before heading back.

Where to stay

Coron town is the natural base. If you plan to dive, look for accommodation near the dive centres so early morning departures are easy.

Good to know

• Bring a mask with clear lenses; this is all about visibility.
• Divers should ask about the thermocline depth and what to expect before descending.
• The climb is short but sharp; wear sturdy sandals.
