The name 'Sai Rung' translates to 'Rainbow' in Thai, referencing the mist often caught in the light at the base of the falls.
The water source originates from the higher elevations of the Khao Lak-Lam Ru National Park mountain range.
Unlike larger commercial waterfalls in Thailand, this site is managed primarily at a local community level.
Sai Rung Waterfall is a multi-tiered cascade located within the Khuekkhak region of Phang Nga province. It features a natural plunge pool at the base of the primary drop suitable for wading and swimming. The waterfall is fed by mountain streams and maintains flow throughout the year, though intensity varies by season. The site is situated within a local forest corridor, providing a shaded environment. Wooden walkways and stairs facilitate access from the parking area to the lower falls. It is a popular localized nature spot often visited by travelers moving between Khao Lak and Takua Pa.
The wooden footbridge overlooking the lower pool provides the clearest view of the main cascade.
Wear water shoes or sandals with grip, as the rocks near the plunge pool are constantly wet and slippery.
Bring insect repellent, as the surrounding forest environment can be prone to mosquitoes.
Pack out all trash, as there are limited waste disposal facilities on-site.
Avoid swimming during heavy rainfall, as flash flooding can occur in the stream channels.
Maintain a modest dress code; avoid swimwear outside of the immediate pool area.
