Sai Daeng Beach Koh Tao – the complete guide

Home » Blog » Asia » Thailand » Sai Daeng Beach Koh Tao – the complete guide

Sai Daeng Beach on Koh Tao offers a perfect escape with amazing scenery just like from a movie. It has beautiful underwater life therefore it’s ideal spot for snorkeling and diving. For us it was certainly one of the best beaches on Koh Tao.

We created short but detailed guide about Sai Daeng beach with all important information so make sure you’ll read it until end.

Where is Sai Daeng Beach?

Sai Daeng Beach Koh Tao is on the southeastern part of the island, not so far from Chalok Baan Kao Beach. It’s relatively close to Sairee beach and main town. Koh Tao is not a big island therefore everything seems to be close.

Don’t forget to save the location to your google maps. You can also load the navigation before going to Sai Daeng Beach in case you’ll lose signal.

Where to stay on Koh Tao

The most popular area to stay is around Sairee Beach. You’ll find most restaurants around. However, this area is also a bit too loud, both during the day and night. If you’re coming to Koh Tao to relax, stay near one of many beaches. Our favorite is Tanote Bay.

Parking fee: free

Sai Daeng Beach Koh Tao can be reached on motorbike, taxi or you can simple take a walk. The most convenient option will of course be motorbike which can be rented from 200 THB per day. Taxi will be always more expensive than renting a motorbike.

Since parking is almost right next to the beach you just have to walk around 50 meters from parking to get to the beach.

About Sai Daeng Beach

The beach is known for its beautiful scenery, crystal clear waters and also for beautiful underwater life. Sai Daeng Beach Koh Tao is great for swimming, sunbathing and snorkeling.

Sai Daeng beach is secluded little gem of Koh Tao. In fact you won’t find a lot of people on the beach, if i remember correctly we were on the beach just with few more people.

On the Sai Daeng Beach you’ll find several restaurants. There isn’t as many restaurants as in other more developed areas of the island but you can still find some thai and western cuisines which will suit to most of the people.

TIP: Did you know that all ATMs in Thailand charge you 220TBH (6€) for withdrawal? It’s a lot, right? Keep this in mind and rather than withdrawing little amounts too often do it once or twice in large amounts.

On the beach you won’t find any showers neither much space in shadow where you can hide from strong sun. There are few sunbeds though which can be rented.

Sai Daeng Beach Koh Tao is surrounded by beautiful boulders so if you get bored you can head out to explore the area. It’s also good for some cliff jumping.

Sai Daeng Beach snorkeling

What we loved the most about the beach was of course underwater life. Sai Daeng Beach was our second favorite beach for snorkeling right after Tanote Bay which is without a doubt the best spot for snorkeling on the island.

I can say that Tanote Bay is the best snorkeling spot of Koh Samui, Koh Phangan and Koh Tao and you should certainly not miss this place during your stay on the island.

Spectacular and colorful corals can be found just few meters from the shore of Sai Daeng beach. Going to the water can be a little bit hard during low tide but it’s not impossible, just be careful.

We saw a lot of beautiful fish and corals in the water. There is also a chance you’ll see turtles or black tip reef sharks. But keep in mind that seeing a shark is not something common.

The best time to visit Sai Daeng Beach

sunny weather icon

Dry season: December – August

monsoon icon

Rainy season: September – November

I highly recommend planning your trip during the dry season, which starts in December and ends in August.

Just to let you know, the peak season generally has excellent weather. However, if you prefer fewer crowds and want to save money, the shoulder season (June to November) might be a better option for you.

Just keep in mind that this period coincides with the monsoon season, therefore you may experience occasional rain showers.

But if you want to sunbathe, feel free to come anytime during the day. There will be enough space for everyone on the beach. We were almost alone on the beach, just us and a few more tourists.

The water is deep enough during a low tide as well as during a high tide. Therefore you can come anytime during a day and you’ll certainly enjoy swimming and snorkeling.

Koh Tao tides

Not many people realize this, but Koh Phangan, Koh Samui, and Koh Tao do not have typical 4 tides per day. There are only 2. Between December and March is a high tide season. This means high tide is stronger and water is deeper than in the other seasons.

During summer, it’s low tide season, and water is too shallow on some beaches. In some months, you only get low tide during daylight. Then, it’s essential to choose the right beach to actually enjoy swimming.
