An up-to-date guide to exploring the 20 m high Sai Rung Waterfall in Khao Lak Thailand.

While not as spectacular as some of the falls you might find in The Philippines like Kawasan Falls or Indonesia’s Sendang Gile waterfalls, Sai Rung Waterfall is still one of the best things to do in Khao Lak.

The Sai Rung or “Rainbow” in Thai is a 20 m waterfall with a clear swimming pool at the bottom which is perfect for cooling down in the midday Thai heat.

The best part is this spot is not particularly popular so you might have it all to yourself. This was the case when we visited which made for a relaxing time.

How to get to Sai Rung Waterfall

Sai Rung Waterfall is located in Khuekkhak and is only a 15-minute scooter ride from downtown Khao Lak.

The best way to get to Sai Rung Waterfall is to rent your own motorbike for around 200-300 baht per day and ride yourself. Remember to grab a helmet when you hire a bike as this is important to have when riding in Thailand. Alternatively, there are plenty of Tuk Tuk drivers who would be happy to take you to the falls.

Starting from Khao Lak main road ( Phet Kasem Road), drive North for roughly 10 minutes. Take a right turn at River Garden Restaurant and Bar, on the right. This turn is directly opposite the turn-off to Pak Weep Beach. Keep riding through the jungle and local farms, along the azure blue river until you reach a parking area with signs for the waterfall.

Unlike Ton Chong Fa Waterfall there is no government tourist tax upon reaching this waterfall, however, you may be asked to pay a small fee of 50 baht to park your motorbike.

This money goes to the family who owns the land and is their primary income, so I was happy to pay for it.

Tip: Remember to organize a return time with the driver if you do not have your own transport as there may be limited service at the waterfall and it might end up with a long walk back to town.

What to Expect at Sai Rung Waterfall

If you're looking for a place to escape the Thai heat, then this is a great spot to relax.

There is a shallow swimming hole under the waterfall that serves as a great natural pool. There are some freshwater fish who live here and like to eat the dead skin on your feet so if you feel something nibbling this might be the case.

I visited this waterfall several times to cool down after a hard morning Muay Thai session. It is a great option as it is uncrowded by tourists and those that I did see were local families escaping the hot midday sun.
