You’re sitting on a wooden pier, the kind that creaks under a light breeze. The air smells like salt and drying fish, not expensive sunblock. Across the water, the limestone karsts of Phang Nga Bay rise up like jagged emerald teeth. There isn’t a single jet ski in earshot. No one is trying to sell you a "Same Same But Different" t-shirt. This is Thailand Koh Yao Yai.
Honestly? It’s not for everyone.
If you want the neon-lit madness of Patong or the "Gram-famous" beach clubs of Koh Samui, you will be bored out of your mind here. There are no malls. The nightlife is basically a gekko chirping on your porch. But for those of us who feel like Phuket has become a giant, humid theme park, this island is the antidote.
The "Big" Island That Time Forgot
Koh Yao Yai literally translates to "Big Long Island." It’s the larger, sleepier sibling of Koh Yao Noi. While Noi has the cute boutique cafes and a slightly more "developed" hipster vibe, Yai is still very much a place where people live, work, and harvest rubber.

Most of the island is covered in dense jungle and rubber plantations. You’ll see the white sap dripping into coconut shells as you ride past on a scooter. It feels lived-in. You’ll pass local schools where kids wave at you, and water buffaloes lounging in mud pits that look way more relaxing than any five-star spa.
Getting There is Half the Fun (Or a 30-Minute Blur)
You can’t fly here. Thank god. You have to earn it, though not by much.
- From Phuket: Head to Bang Rong Pier. Speedboats leave frequently (usually every hour or so until 4:00 PM) and take about 30 minutes. It’ll cost you around 400 THB.
- From Krabi: You’ll likely depart from Nopparat Thara or Thalane Pier. It’s a bit longer, maybe 45 to 60 minutes, but the views of the islands along the way are ridiculous.
When you arrive at Klong Hia Pier or Manoh Pier, don’t expect a fleet of air-conditioned SUVs. You’re getting into the back of a songthaew (a converted pickup truck) or renting a semi-automatic scooter. My advice? Rent the scooter. The roads are paved but quiet, and it’s the only way to find the hidden spots.
Where the Sand Meets the Sky: Laem Had Beach
If you’ve seen a photo of Thailand Koh Yao Yai, it was probably Laem Had. This is the famous sandbar that curves out into the ocean toward Koh Yao Noi.

At low tide, it’s magic. The water recedes to reveal a blindingly white path of sand that makes you feel like you’re walking on water.
Pro Tip: Check the tide charts. Seriously. If you go at high tide, you’re just looking at a regular beach with some trees. Use an app like Tide Alert or just ask your guesthouse owner. They know the rhythm of the water better than any satellite.
The Elephant in the Room: The "Muslim Island" Factor
This is a point where a lot of travel blogs gloss over the details, but it’s important for your expectations. Koh Yao Yai is predominantly Muslim. This isn't a "party" island.
- Alcohol: You won't find it at every corner store. Most high-end resorts like Anantara or Santhiya serve whatever you want, but local mom-and-pop restaurants might not. Don't be "that" tourist—if they don't serve it, don't push it.
- Dress Code: When you’re at your resort pool, bikinis are fine. When you’re driving through the local villages or stopping at a market, throw on a t-shirt and some linen pants. It’s about respect.
- The Adhan: You will hear the call to prayer. It’s beautiful, honestly. It adds a layer of soul to the island that you don't get in the more commercialized parts of Thailand.
Where to Sleep: Jungle Luxury vs. Salt-of-the-Earth Stays
You have two very different paths here.
On one hand, you have the Santhiya Koh Yao Yai Resort & Spa. It’s basically a giant, hand-carved teak palace built into a cliff. It looks like something out of a Thai fairy tale. If you want a private pool and a view that makes you want to cry, stay there.
On the other hand, there are places like Yao Island Resort and Farm. It’s run by local sisters, it’s rustic, and you’ll probably have a cat or a chicken wander into your breakfast area. You’ll learn more about the island in ten minutes talking to them than you would in a week at a five-star hotel.

Food That Actually Tastes Like Something
Don't look for Italian fusion. Look for Khanom Jeen (rice noodles with spicy curry) or fresh grilled snapper.
There’s a little spot near the Loh Jark Pier—basically just a few plastic tables under a tin roof. They serve a spicy seafood salad (Yum Talay) that will blow your head off and then make you ask for seconds. That’s the real Thailand Koh Yao Yai experience. Cheap, spicy, and served with a genuine smile.
The Reality Check: Limitations to Keep in Mind
I promised to be an expert, and experts don't sugarcoat.
The internet can be spotty if a storm rolls in. ATMs exist, but they sometimes run out of cash or just decide not to work with your specific card. Bring more Thai Baht than you think you need.
Also, the "beaches" are tidal. At low tide, the water goes way, way out, leaving behind mudflats and rocks in many areas. This isn't the Maldives where the water is waist-deep and turquoise 24/7. It’s a working ecosystem.
Is It Right For You?
If your idea of a vacation involves 7-Elevens on every corner, loud music, and meeting other 20-somethings to do buckets of cheap gin, Thailand Koh Yao Yai will be a nightmare for you. You’ll feel trapped.
But.
If you want to remember why people started traveling to Thailand in the first place—the kindness, the silence, the feeling of being somewhere that doesn't care if you're there or not—then this is your spot.
Your Actionable Next Steps
- Book your boat early: If you’re coming from Phuket Airport, give yourself at least 2 hours between landing and the pier departure. Traffic to Bang Rong can be a nightmare.
- Download offline maps: Google Maps works, but signal drops in the middle of the rubber plantations.
- Pack a dry bag: You’ll be on boats and scooters. Tropical downpours happen fast.
- Learn three words: Sawasdee-ka/krub (Hello) and Khop khun ka/krub (Thank you). On an island this local, it goes a long way.
Leave the "hustle" at the pier. Rent a bike. Get lost. That’s the only way to actually see the island.
