While not as spectacular as some of the falls you might find in The Philippines or Indonesia, Sai Rung Waterfall is still a must when in Khao Lak. Sai Rung or “Rainbow” in Thai is a 20 M waterfall with a clear swimming pool at the bottom.

Where to find Sai Rung Waterfall
Sai Rung waterfall is located in Khuekkhak and only a 15-minute scooter ride from downtown Khao Lak. The best way to get there is to rent your own motorbike for around 150-200 baht per day and ride yourself. Or, if you prefer, there are plenty of Tuk Tuk drivers who would be happy to take you to the falls.
From Khao Lak main road ( Phet Kasem Road), drive North for roughly 10 minutes. Second, 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.
Although there is no government tourist tax upon reaching this waterfall, 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.
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. However, there are some freshwater fish who live here and like to eat the dead skin on your feet. I guess some people are into that.
I visited this waterfall several times to cool down after a hard morning Muay Thai session. It is usually uncrowded and those that I did see were usually local families escaping the hot midday sun.
