The Tangke Saltwater Lagoon: Nature’s Hidden Infinity Pool

Gigantes Islands Tour Packages

Tucked away behind towering limestone cliffs on Gigantes Sur lies one of the most enchanting natural wonders in the Philippines — the Tangke Saltwater Lagoon. Often called “Nature’s Hidden Infinity Pool,” this secluded spot in the Islas de Gigantes is a favorite stop for island hoppers seeking a touch of serenity and magic during their Gigantes Island tour.

With its emerald-green water reflecting the cliffs that surround it, the Tangke Lagoon feels like a scene straight out of a dream. It’s smaller than El Nido’s lagoons but just as mesmerizing — and far less crowded. If you’re planning to explore island hopping in Iloilo, this hidden gem deserves a top spot on your itinerary.

What Is the Tangke Lagoon?

The word “Tangke” means “tank” in Filipino — and true enough, the lagoon is a natural rock basin that fills up with seawater during high tide. Enclosed by steep limestone cliffs, it creates a calm saltwater pool that shimmers in shades of green and blue.

It’s located on the western side of Gigantes Sur, accessible only by boat and tide timing. The lagoon is surrounded by jagged cliffs reminiscent of Palawan’s karst formations, offering a raw, untouched atmosphere that feels worlds away from the mainland.

The Story Behind Tangke Lagoon

Locals say the lagoon was discovered generations ago by fishermen seeking refuge from rough seas. Over time, word spread about its breathtaking beauty, and it became a highlight for tourists exploring the Islas de Gigantes. Many also believe the lagoon is enchanted — home to spirits that protect the island and its visitors. Because of this, locals often offer quiet respect before entering its waters.

Whether or not you believe in legends, one thing is certain: the Tangke Lagoon radiates a peaceful energy that makes every visitor feel humbled by nature’s artistry.

How to Get to Tangke Lagoon

Reaching the Tangke Lagoon is an adventure in itself. Here’s how to include it in your Gigantes Island tour:

  • Step 1: From Iloilo City, ride a van or bus to Estancia Port or Bancal Port in Carles (around 4 hours).
  • Step 2: Board a passenger or private boat bound for Gigantes Sur (1.5–2 hours).
  • Step 3: Join an island-hopping tour that includes the Tangke Lagoon, usually alongside stops like Cabugao Gamay and Antonia Beach.

Tip: Visit during high tide for the best swimming experience — that’s when the lagoon is full and calm. During low tide, the water level drops, and the pool may become too shallow for swimming.

What Makes Tangke Lagoon So Special

Unlike typical beaches, the Tangke Lagoon offers a more private and intimate escape. Here’s what makes it stand out:

  • Natural Infinity Pool Effect: The lagoon appears to blend seamlessly with the horizon, especially when viewed from higher rocks — a perfect natural illusion.
  • Emerald Waters: The clarity of the water depends on the tide and sunlight, shifting between turquoise and deep jade hues throughout the day.
  • Peaceful Ambiance: Surrounded by limestone cliffs, the lagoon muffles outside noise, leaving only the sound of gentle waves and birdsong.
  • Local Charm: Boatmen and guides often share stories and myths about the lagoon, adding a cultural touch to your adventure.

When Is the Best Time to Visit?

The best time to visit the Tangke Lagoon is from November to May — the dry season — when sea conditions are calm. The lagoon is particularly magical between 10:00 AM and 2:00 PM, when sunlight hits the water directly, creating a glowing emerald color perfect for photography.

Avoid visiting during low tide or heavy rain, as boats may not be able to enter the lagoon due to shallow waters or slippery rocks.

Things to Do at Tangke Lagoon

1. Swim in Tranquil Waters

Take a dip in the cool, crystal-clear water surrounded by nature’s towering walls. It’s one of the most peaceful swimming spots in the Philippines — no waves, no current, just stillness and beauty.

2. Jump from the Rocks (If You’re Brave Enough!)

For thrill-seekers, there are safe ledges from which you can jump into the lagoon. Always follow your guide’s instructions, as the water depth changes with the tide.

3. Capture Stunning Photos

Every corner of the Tangke Lagoon is photogenic — from reflections on the water to the limestone textures and sunbeams filtering through the cliffs. A drone shot from above reveals its “hidden infinity pool” effect in full glory.

4. Listen to the Local Legends

Ask your guide about the myths surrounding the lagoon — some say mermaids guard its waters, while others speak of spirits that ensure travelers’ safety. These stories add a layer of mystique to your visit.

Travel Tips for Visiting Tangke Lagoon

  • ✔️ Visit during high tide for the best water level.
  • ✔️ Wear aqua shoes — rocks around the area can be sharp.
  • ✔️ Bring waterproof bags for your gadgets.
  • ✔️ Respect the lagoon — no shouting, no littering, and no diving from unsafe heights.
  • ✔️ Avoid crowding. If you’re joining a group tour, wait your turn to swim or take photos.

Entrance and Environmental Fees

A minimal environmental fee (₱75–₱100) is collected from visitors. This goes toward maintaining cleanliness and supporting the local eco-tourism programs that protect the lagoon and surrounding islets. Some tours already include this in the package price — check with your operator before your trip.

Responsible Tourism at Tangke Lagoon

The lagoon is a symbol of how eco-tourism in Gigantes can flourish through local stewardship. The community of Carles has worked hard to preserve the lagoon’s pristine condition. As a responsible traveler, you can help by:

  • Bringing back your trash to the boat or mainland.
  • Avoiding sunscreen with harmful chemicals (use reef-safe brands instead).
  • Refraining from climbing or carving on limestone cliffs.
  • Supporting local guides and operators who follow sustainable practices.
