The quiet protected island where nature rests undisturbed.

Koh 2 (Koh Pa Yang): the quiet, rocky guardian of the Similans

the untouched rocky sanctuary that stays wild at the start of the Similans

Koh 2 — also called Koh Pa Yang and known locally as Koh Sŏrng (sŏrng = 2 in Thai) — is one of the most peaceful, untouched islands in the Similan chain. It’s small, rocky, and beautifully quiet, sitting just above Koh 1 like a gentle guardian. There’s no beach, no landing, and no snorkeling stop here — just pure nature, dramatic granite shapes, and the soft beginning of the Similan story.

To say it like a local

Koh Pa Yang = koh pah‑yang (soft “pah”, gentle “yang”).
Koh Sŏrng = koh sŏrng (sŏrng means 2 in Thai).

“Koh 2 is the island that stays silent so the sea can speak.”

The first impression of Koh 2

As the boat passes the southern islands, Koh 2 appears like a cluster of smooth granite boulders rising from the sea. It’s small but striking — dark rocks, green patches of forest, and water that shifts from deep blue to soft turquoise around the edges. You don’t stop here, but you feel its presence. It’s the kind of island that makes you look twice.

Pam always points at the rock lines and says, “This is where the Similan shapes begin.”

The mood of Koh 2

Koh 2 feels raw, natural, and untouched — a quiet transition between the turtle sanctuary of Koh 1 and the brighter islands ahead.

Expect:

• dramatic granite formations
• deep blue water around the rocks
• quiet, untouched forest
• a peaceful, almost meditative mood

“Koh 2 is the calm breath before the Similan blues start glowing.”

Why Koh 2 is protected

Like Koh 1, Koh 2 is part of the strictly protected southern zone of the Similan Islands. There are no tours stopping here, no snorkeling, and no beach access. The island is kept wild to protect the natural ecosystem — especially the marine life that thrives around its rocky edges.

The rocks and shallow reefs around Koh 2 are home to:

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

It’s a quiet, living sanctuary that remains untouched.

What you see from the boat

Even from a distance, Koh 2 has its own beauty. The rocks rise in smooth, rounded shapes, the forest sits softly on top, and the water around it glows in shifting shades of blue.

From the boat, you might notice:

• waves breaking gently against the granite
• birds circling above the cliffs
• the contrast between dark rock and bright water
• the peaceful curve of the island

“Koh 2 is the kind of beauty you don’t touch — you just admire.”

The role of Koh 2 in your Similan day

Koh 2 is the second chapter of the Similan chain — a quiet, rocky introduction before the turquoise magic of Koh 4, Koh 7, Koh 8, and Koh 9. It sets the tone: calm, natural, and beautifully untouched. It’s the island that reminds you the Similans are not just beaches — they’re a whole world of shapes, colors, and quiet moments.

Why people remember Koh 2

• its dramatic granite formations
• its peaceful, untouched mood
• its role as a protected natural zone
• the way it marks the beginning of the Similan journey
• the contrast between its quietness and the bright islands ahead

Koh 2 is the soft, rocky heartbeat at the start of the Similan chain — the sanctuary that stays wild so the rest of the day can shine.
