Pha Rom Yen Waterfall is regarded as one of the most beautiful and distinctive waterfalls in Uthai Thani Province. Hidden quietly within the Pla Ra Mountain Range in Ban Rai District, the waterfall features a large cascade flowing down a steep limestone cliff. Unlike typical waterfalls where water plunges in heavy streams, the water here disperses into fine mist, resembling gentle rainfall or long strands of silk flowing gracefully along the cliff face.

The limestone cliff is covered with lush green moss and algae, allowing the water to glide softly over the surface. This creates a delicate, soothing visual effect that gives the entire area a cool and refreshing atmosphere, perfectly reflecting the meaning of the name “Pha Rom Yen,” which conveys a sense of shade and coolness. The overall scenery appears gentle and calming, rather than dramatic or forceful.

Another charm of Pha Rom Yen Waterfall lies in the rich forest environment along the walking trail leading to the site, which stretches approximately 600–800 meters. Visitors pass through a natural tunnel formed by large trees and dense forest canopies overhead. The path is filled with humidity, birdsong, and the quiet rhythm of the forest, turning the walk itself into a therapeutic experience that naturally relaxes both body and mind.

Upon reaching the waterfall, especially during periods of abundant water flow, fine water droplets spread throughout the surrounding area, creating a cool and refreshing sensation. Even without entering the water, visitors can clearly feel the freshness simply by standing nearby and enjoying the scenery. This makes the area ideal for rest and peaceful contemplation in nature.

Beyond the main waterfall, the surrounding limestone cliffs present a mysterious and almost sacred atmosphere. Naturally eroded rock formations blend harmoniously with ferns and plants clinging to the cliff walls, forming scenery reminiscent of a classical Chinese landscape painting. The area has been preserved in its natural and untouched state as much as possible, allowing visitors to experience a high level of tranquility and privacy, distinct from commercialized waterfalls elsewhere.

For landscape photographers, Pha Rom Yen Waterfall serves as an excellent natural classroom for capturing flowing water in soft, silky lines, especially through the use of slow shutter speeds that contrast the movement of water with the deep green tones of moss and algae. Artists and naturalists often spend hours here, absorbing the intricate details of the small ecosystems on the rocks and the grandeur of the surrounding limestone cliffs.

Pha Rom Yen Waterfall can thus be described as a hidden “silk waterfall” deep within the forest—an enchanting destination that reveals the gentle beauty of nature delicately carved into limestone, and a perfect retreat for those seeking to escape the bustle of everyday life and immerse themselves in the soothing green of the forest.

By Private Car:

• From Ban Rai district, take Highway 3011 (Ban Rai–Phu Bon) for about 10 km. Look for the sign for Pha Rom Yen Waterfall on the right. Turn into the dirt road for about 2 km to the parking lot, then trek for 15–20 minutes.

By Public Transport:

• Take a van to Ban Rai district center, then hire a local private vehicle (Skylab or pick-up truck), as there is no regular public transport directly to the trailhead.

Best Season:

• The peak time is September to November during the late rainy season when the water flow is most beautiful and the forest is at its greenest.

Equipment:

• Wear sneakers or hiking boots with good grip, as the path can be slippery from moss and tree roots. Carry insect or leech repellent just in case.

Photography:

• Use a tripod to capture the flowing "silk" effect of the water. Be mindful of the heavy mist, which can quickly fog up your camera lens.

Safety:

• Please help keep the forest clean by taking your trash out. It is recommended to start heading back by 16:30 to reach the parking lot before dark.
