Tham Heo Sinchai

Tham Heo Sinchai is a shallow cave shrine off Highway 2222, about 7 kilometres from Khong Chiam and just inside the edge of Kaeng Tana National Park. A reclining Buddha image sits beneath the rock overhang, and in the rainy season a stream spills over the cave mouth as a thin waterfall, giving the whole space a shaded, cool feel that draws meditators as much as sightseers.

What’s there

The cave is reached by a short walk (around 200 metres) off the highway into the national park boundary. Inside, alongside the reclining Buddha, are a statue of a hermit and an image of Phra Mae Thorani, the earth goddess, among several other Buddha figures. Large boulders sit stacked around the entrance, and seasonal wildflowers grow through the rocks depending on the time of year. Above the cave, an open meadow gives a different view of the same hillside.

The site is treated as a meditation retreat rather than a standard sightseeing stop. The forest temple built around the same cave — Wat Tham Heo Sin Chai, founded by Luang Pu Khamla Pakuno, with its own wihan and a large standing Buddha visible from the Mun River bridge — shares this ground, so don’t be surprised to find monks or lay practitioners in quiet practice nearby.

Insider Tip: Visit at the end of the rainy season (October-November) if you want to see the waterfall running — in the dry months the stream over the cave mouth can reduce to almost nothing.

Watch out: This is an active meditation site. Keep your voice down, don’t touch the Buddha images or rock formations, and expect minimal lighting inside the cave — bring a torch if you want a proper look.

Practical

There’s no ticket booth at the cave itself, though Kaeng Tana National Park nearby charges its own park entry fee if you’re combining the two. For a fuller day around Khong Chiam, Ubon Ratchathani town has the rest of the district’s riverside sights within easy reach.
