A Pam‑approved countdown of blues that keep getting bluer.
"Trust me, I’ve floated here"
There are blues you admire… and then there are blues that make you stop, stare, and forget whatever you were thinking about five seconds ago. I’ve been in these waters — literally — and I can confirm: Thailand doesn’t just do blue. It specializes in it.
From soft, dreamy turquoise to deep, velvety sapphire, this is your curated countdown of the bluest of the blue, ranked by pure chromatic drama.
And yes — every shade here is Pam‑approved.
Some islands have blue water. These islands have blue personality.
10. Koh Hey
A gentle, welcoming blue — the perfect warm‑up shade. Calm, clear, and endlessly floatable. The sea equivalent of a soft opening.
Pam‑approved because: this is the “first cleanse” of island blues. Soft, kind, and perfect for beginners.
Blue mood
- Shade: pastel turquoise
- Vibe: easy, breezy, beginner‑friendly
- Best for: first dips, lazy floats, sun‑soaked daydreaming
This island doesn’t do blue, it does emerald
9. Koh Phi Phi
Phi Phi doesn’t whisper; it performs. Turquoise so bright it practically hums. Every cove is a cinematic moment waiting to happen.
Pam‑approved because: this is the bold‑glow blue — the same energy you get when your skin is behaving beautifully.
Famous for a reason

8. Koh Hong (Krabi)
Inside Koh Hong’s lagoon, the water becomes glossy, reflective, and editorially smooth. It’s the kind of blue that knows its angles.
Pam‑approved because: this is the “serum finish” of the sea — smooth, reflective, and quietly premium.
If water could pose, this would be its good side.
I swear the clarity is real
7. Koh Surin
A serene, glass‑like blue that feels almost weightless. Snorkeling here is like slipping into a luxury aquarium — minus the glass.
Pam‑approved because: this is clarity without harshness — the exact philosophy behind Pam.

Some blues sparkle. This one glows.
The blues get serious now!

The grand finale
"Trust me, this one changes you"
1. Koh Similan
The pinnacle. The masterpiece. The final boss of blue. Koh Similan’s waters are so clear, so luminous, so impossibly pure that they reset your entire understanding of the color.
I’ve been here — and once you’ve seen this blue, you carry it with you.
This is the shade that makes time slow down.
The shade that makes you float longer.
The shade that ruins all other beaches for you — in the most delightful way.
Pam‑approved because: Similan is the blueprint. The clarity standard. The glow philosophy. The reason Pam exists.
Why Similan wins
