Khao Pathawi

Khao Pathawi is a 750-metre limestone ridge rising 253 metres above the rice paddies of Taluk Du subdistrict in Uthai Thani’s Thap Than district, roughly 38 km from the provincial town. Weathered grey outcrops give the hill its shape, and its slopes hold around 30 caves — a rare concentration for a hill this size.

The caves are the main reason to come. Tham Prathun and Tham Rusi (Hermit Cave) hold stalactites and stalagmites typical of limestone karst, while smaller openings such as Tham Bandai and Tham Chong Lom riddle the rest of the ridge. Excavations in several caves turned up prehistoric stone tools and human skeletal remains, evidence that people used this hill thousands of years before Wat Khao Pathawi was built at its base in 1928. A small local museum displays some of the finds alongside general Thap Than district history.

Troops of monkeys live on the shaded lower slopes and are usually the first thing visitors notice, often waiting near the base looking for food. The hill sits inside a farming district, and the contrast is part of the draw — pale limestone cliffs rising straight out of flat, green rice fields with no other high ground nearby, visible for kilometres before you reach the base.

Watch out: Keep any food out of sight in a closed bag — the monkeys here are used to visitors and will grab an open snack out of your hand.

A flight of steps and shaded paths climb through the trees to viewpoints over Thap Than’s fields and the lower hills beyond; it’s a steady climb rather than a technical one, manageable in trainers. The setting stays rural and undeveloped — no ticket booth, no gift shop, just the hill, its temple and the farmland around it, which is part of the appeal if you’ve already covered Uthai Thani’s better-known sights.

Insider Tip: Go early, before 9am — the caves are cooler, the monkeys are more active near the base, and the haze that builds over the plains by midday hasn’t yet dulled the view from the top.

Khao Pathawi combines easily with Khao Praya Phai Ruea, another cave-riddled limestone hill elsewhere in Uthai Thani, if you’re working through the province’s karst scenery in one trip. Entry is free and there’s no set opening hours — the site is effectively always accessible. Bring water, sun protection and shoes with grip for the steps; your own transport is the only practical way in, since the hill sits well off any public transport route.
