Lang Khai Bay

Lang Khai Bay is a small section of sand punctuated by granite rocks, tucked into an easy-to-miss cove on the east coast of the island between Aow Leuk Bay and Tanote Bay. It is one of the best hidden and lesser-known beaches on Koh Tao. Very few tourists make it here, and even among long-term residents it remains largely unfrequented. The bay is nestled in a valley between two hillsides. A small golden patch of sand sits in between rocky boulders on both sides, creating a very private atmosphere.


You can easily reach Lang Khai Bay by turning off the Tanote Bay road. After a couple of hundred metres you’ll take a left as the main road takes a steep downward drop. The turn for Lang Khai is signposted to “Lang Khai Bay and Yang Bungalows.” The narrow road becomes narrower as you descend. In the end, it transitions into a dirt track just before arriving at the parking area near Yang Bungalows.


There are no fees or charges to access Lang Khai Bay. 

Services & Facilities

There are no facilities at Lang Khai Bay itself in terms of renting snorkel gear or purchasing food or drinks. Nevertheless, should you head back to the main road and descend the hill, you will come across New Heaven restaurant and Ban Talay restaurant, both offering a variety of Thai and Western culinary delights. There are amazing viewing platforms looking down into Aow Leuk Bay. You can see across the glistening blue sea to Shark Island, Koh Phangan and Koh Samui & beyond. 

Swimming and Snorkeling

As one of the least visited stretches of accessible coastline on Koh Tao, the conditions underwater are spectacular and boast healthy, colourful reefs and a wide variety of marine life. Koh Tao beaches and bays on the east coast of the island tend to be home to some of the rarer fishes than the more heavily frequented beaches and dive sites on the west coast of the island. Lang Khai Bay follows the same pattern, allowing you to spend countless hours enjoying the sight of beautiful corals and tropical fish.  

Recommended for… Having a Beach to Yourself

In most cases, visitors who make the trip to Lang Khai Bay will have this beautiful cove all to themselves. Lay down your towel or sarong, sunbathe on the rocks, or catch some shade in the shadow of one of the larger boulders. No matter how you choose to utilize your time, you can be assured that it will be serene, tranquil, and probably be people free!
