Visit the Emerald waters of Pileh Lagoon, Phi Phi Islands

Towering limestone cliffs, jewel-toned water so clear you can see fish from the boat, and the kind of calm that makes you want to float for hours. That’s Pileh Lagoon—also known as Pi Leh Lagoon, a tucked-away paradise on Phi Phi Leh that feels like a natural swimming pool surrounded by cliffs.

You won’t find a beach here. No snack shacks or selfie sticks either. Just still, emerald water and steep canyon-like walls that make you feel like you’ve stumbled into a lost world. Whether you’re snorkeling, swimming, or just soaking in the views, this is one of Phi Phi’s unmissable stops, and we’ve got the complete guide to help you make the most of it.

What is Pileh Lagoon?

Pileh Lagoon is a shallow, sheltered cove carved into the western side of Phi Phi Leh. It's famous for:

Boat sailing to Maya Bay through limestone cliffs, Phi Phi Islands
  • Limestone cliffs that wrap around the lagoon in a dramatic horseshoe shape.
  • Crystal-clear waters, with shades that shift from green to turquoise depending on the sun.
  • No beach and buildings, just open water and vertical rock faces.
  • Depths of up to 20 meters, making it swimmable at the center but shallow enough to walk through water near the entrance.
  • Great snorkeling visibility, with coral outcrops and tropical marine life all around.

Swimming and snorkeling

The lagoon is tailor-made for a calm swim. With the gentle slope of the seabed, you can float comfortably or paddle up toward the cliffs.

Things you might see:

Best photo tips

Aim for golden hour:
Light hits the cliffs at a warm angle just after sunrise or before sunset.

Use the reflections:
Shoot low to capture mirror-like images on calm water.

Bring a polarizer:
A polarizing lens filter cuts surface glare and brings out deeper greens.

Go underwater:
Rent a GoPro or waterproof case to film corals and sea life.

Fly a drone (with permission):
Permission is required to fly a drone. Check for local drone rules first.
