An untouched sanctuary of granite, forest, and deep blue water.

Koh 3 — also called Koh Pa Yan and known locally as Koh Săam (săam = 3 in Thai) — is the final member of the southern Similan sanctuary trio. Like Koh 1 and Koh 2, it is strictly protected, untouched, and beautifully quiet. There’s no beach, no landing, and no snorkeling stop — just granite, forest, and deep blue water moving gently around its edges.

To say it like a local:
Koh Pa Yan = koh pah‑yan (soft “pah”, gentle “yan”).
Koh Săam = koh săam (săam means 3 in Thai).

“Koh 3 is the island that stays wild so the sea can stay calm.”

The first impression of Koh 3

Koh 3 rises from the water in smooth granite curves, softened by patches of green forest. It’s small but striking — a quiet stone island that feels ancient and untouched. As the boat passes, the water shifts from deep blue to soft turquoise around the rocks, creating a calm, meditative mood.

Pam always points at Koh 3 and says, “This is the last quiet breath before the turquoise begins.”

The mood of Koh 3

Koh 3 feels still, steady, and deeply natural. It’s the island that doesn’t ask for attention — it simply exists, beautifully.

Expect:

• rounded granite boulders
• deep blue water hugging the rocks
• soft green forest on top
• a peaceful, sanctuary‑like atmosphere

“Koh 3 is the quiet stone heartbeat of the southern Similans.”

Strict protection — just like Koh 1 and Koh 2

Koh 3 is part of the southern protected zone of the Similan Islands, along with Koh 1 and Koh 2. These three islands form a sanctuary where nature is allowed to remain completely untouched.

This means:

• no landing
• no snorkeling
• no diving
• no beach access
• no tour stops

The island is protected to preserve its natural ecosystem and the marine life that thrives around its rocky edges.

Around Koh 3, you’ll find:

• small reef fish
• coral patches
• sea birds resting on the boulders
• gentle currents shaping the coastline

It’s a quiet, living sanctuary that remains wild by design.

What you see from the boat

Even from a distance, Koh 3 has a quiet beauty. The rocks rise in smooth, rounded shapes, the forest sits softly on top, and the water glows in shifting shades of blue.

From the boat, you might notice:

• waves brushing the granite
• birds circling above the cliffs
• the contrast between dark rock and bright water
• the peaceful, steady curve of the island

“Koh 3 is the kind of beauty you admire in silence.”

The role of Koh 3 in your Similan day

Koh 3 is the final quiet chapter before the day turns bright and turquoise at Koh 4. It’s the soft transition between the protected sanctuary islands and the glowing, postcard‑perfect beaches ahead.

It reminds you that the Similans are not just beaches — they’re a whole chain of moods, shapes, and quiet moments.

Why people remember Koh 3

• its peaceful, untouched mood
• its dramatic granite formations
• its role as a protected sanctuary
• the way it marks the shift from quiet to turquoise
• the contrast between its stillness and the bright islands ahead

Koh 3 completes the southern sanctuary — the quiet pause before the Similan blues begin to shine.
