Best Beaches in Ko Yao Noi, Thailand

Ko Yao Noi is one of southern Thailand’s most peaceful islands, loved for its uncrowded beaches, Phang Nga Bay views, and slow, local rhythm. If you’re searching for the best beach in Ko Yao Noi, the top contenders are Klong Jark Beach and Pasai Beach both are among the most swim-friendly spots on the island.

1) Klong Jark Beach

If you want the most reliable place for swimming in Ko Yao Noi, Klong Jark Beach is often considered the best option especially because the water is typically deep enough to swim even at lower tide compared to many other parts of the island.
Expect a long, relaxed coastline where you can walk for a while, stop for a drink, and enjoy an unhurried beach day.

Why go: best swimming beach, long sandy stretch, easy beach day
Best for: couples, chill travelers, swim + walk combo
Local tip: Come late afternoon for a softer vibe and fewer people.

2) Pasai Beach

Pasai Beach is the island’s most popular beach zone and runs along much of the east coast, with white sand, palms, and plenty of places nearby to eat or grab a drink. 
It’s a great “base beach” if you want convenience close to local life, casual restaurants, and easy access around the island.

Why go: convenient, lively-but-still-calm, great for casual beach time
Best for: families, easy dining nearby, sunrise walks
Local tip: Try different sections of the coast some areas feel much quieter than others.

3) Tha Khao Bay

Tha Khao Bay is a beautiful, quiet area with scenic views toward the karst islands of Phang Nga Bay especially at sunset but it’s often not ideal for swimming because the water can stay very shallow and recede far at low tide.
If your priority is atmosphere, sunset colors, and a peaceful coastal walk, this is a top pick.

Why go: quiet beach, sunset views, photography
Best for: sunset lovers, peaceful walks, local vibe
Local tip: Check the tide low tide can reveal huge sand flats for walking.

4) Kian Bay

Kian Bay is another option often mentioned among Ko Yao Noi beaches, usually visited for its calm scenery and “away from the main road” feel.
It can be a nice change of pace if you’ve already done Pasai/Klong Jark.

Why go: quieter feel, scenic bay
Best for: relaxed exploration, short beach stop
Local tip: Combine it with a boat day or a coastal ride.
