The waterfall is formed by a natural spring originating from the limestone mountains behind the site.
During the Japanese occupation of Thailand in World War II, a small steam locomotive—now preserved—was displayed here as a memorial to the Death Railway.
The water cascades over a series of calcified limestone terraces rather than a single vertical drop.
The site serves as a frequent rest area for travelers on the route to the Erawan and Sai Yok Yai national parks.
The name 'Khao Pang' translates to 'broken mountain,' referencing the visual appearance of the limestone cliff face.
Sai Yok Noi Waterfall, also known as Khao Pang Waterfall, is a limestone cascade located in Kanchanaburi Province, Thailand. Unlike many other waterfalls in the region, it is fed by a perennial spring, ensuring water flow throughout the year. The waterfall consists of several tiers cascading over limestone rocks into a clear pool suitable for swimming. The site is situated directly beside Highway 323, making it one of the most accessible natural attractions in the area. The surrounding area is developed with picnic tables, food stalls, and designated relaxation zones. It is a popular stopover for visitors traveling deeper into the Sai Yok National Park region.

Wear water shoes, as the limestone rocks in the stream bed can be slippery and uneven.
Bring your own towels and a change of clothes if you plan to swim in the lower pools.
Visit during weekdays to avoid large crowds of weekend picnickers.
Do not leave food unattended, as local macaques are known to scavenge from picnic areas.
Modest swimwear is expected; avoid excessive noise in designated relaxation areas.
