Pha Rom Yen Waterfall

Pha Rom Yen Waterfall isn’t a cascade so much as a curtain: water sheets thinly down a moss-covered limestone cliff in the forest outside Ban Rai, in the hilly west of Uthai Thani, and in low flow it reads more like falling rain than a roaring fall. Entry is free, the car park holds only a handful of vehicles, and the walk in is about 400 metres, roughly 20 minutes each way.

A curtain, not a cascade

The water steps down the cliff face in a few short stages rather than one long drop, pooling shallow at the base rather than carving a plunge pool. Dense forest shades the whole approach, keeping the air noticeably cooler than the open road outside, and the moss stays green through most of the year even when the flow thins to a trickle. It’s a modest, quiet site rather than a developed park (a handful of benches and little else, no vendors lining the path) and even on a weekend it rarely feels crowded.

The walk in

The trail starts on concrete steps, switches to a metal staircase partway up, and finishes on packed forest ground. Sturdy shoes make a real difference on the metal sections when they’re wet, and the rocks around the pools at the base stay slick even outside the rainy season. Move carefully near the water’s edge and skip flip-flops for the walk in.

Insider Tip: Call ahead for a local guide (0 5698 4069) if you’re visiting in the rainy season: the metal stairs get properly slick after a downpour, and someone who knows the current trail conditions is worth the small arrangement.

Watch out: The car park’s small capacity means it can fill on a wet-season weekend; arrive earlier in the day if you’re driving rather than joining a tour.

When to go, and getting there

Flow is seasonal and strongest from around June through October, during and just after the rains; by the hot season (March–May) it can drop to little more than a trickle down the rock, so anyone chasing photos of the falls at full flow should aim for the wetter months. Reaching the falls means driving the Ban Rai–Phu Baon road (Highway 3011) out of Ban Rai town toward Ban Mai Rom Yen village, then following the signed turn to the car park: there’s little in the way of facilities beyond parking, so bring your own water and snacks. Pair it with Namtok Tat Dao, another Ban Rai waterfall a short drive away, or the wider Huai Kha Khaeng Wildlife Sanctuary for a fuller day in western Uthai Thani.
