Discover Koh Yao Yai – Thailand's Best Undiscovered Island
If you’re looking for a quiet, untouched island in Thailand, Koh Yao Yai is the perfect destination. Located in Phang Nga Bay, between Phuket and Krabi, this hidden gem offers crystal-clear waters, white-sand beaches, and lush jungles—without the crowds. While just a short boat ride from the bustling shores of Phuket, Koh Yao Yai remains unspoiled, preserving an atmosphere of Old Thailand.
In this guide, we’ll cover how to get there, the best places to stay, and must-do activities for an unforgettable escape to Koh Yao Yai.
Why Visit Koh Yao Yai?
Koh Yao Yai, meaning "The Long Big Island", is the larger of the two Koh Yao Islands (the other being Koh Yao Noi). While both islands offer a relaxed and authentic Thai experience, Koh Yao Yai is even more untouched. Here’s why you should visit:
- No mass tourism – Unlike Phuket and Krabi, Koh Yao Yai remains a peaceful retreat.
- Stunning beaches – Explore Laem Haad Beach, a breathtaking sandbank that disappears at high tide.
- Local culture – Experience an island where fishing villages, rice paddies, and rubber plantations still thrive.
- Adventure & relaxation – From kayaking in mangrove forests to simply lounging on a quiet beach, there’s something for every traveler.
How to Get to Koh Yao Yai
Reaching Koh Yao Yai is easy and scenic, with regular boats connecting the island to nearby tourist hubs.
- From Phuket: A 30-minute speedboat ride from Bang Rong Pier (about 400 THB per person).
- From Krabi: Boats leave from Tha Len Pier and take around 40 minutes.
- From Phang Nga: Local boats depart from Tha Dan Pier, offering a more traditional journey.
Tickets can be purchased online or directly at the pier.
