Most of the waterfalls people swim at in Phetchabun sit in Khao Kho and Lom Sak districts — the mountain zone in the northwest of the province, where the air runs cooler than in town. The falls here are mostly single-tier rock falls, so you don't have to climb far: it's a short walk in from the car park and you're there. They make an easy stop on the way up to Khao Kho or coming down from Phu Thap Boek. The two everyone visits and can swim at comfortably are Sri Dit and Than Thip; the rest are smaller falls that still see fewer crowds.
Sri Dit Waterfall — a wide pool to swim in, cold water year-round
Sri Dit Waterfall sits in Nong Mae Na subdistrict, Khao Kho. It's a large single-tier rock fall, around 30 metres high and 50 metres wide, with the water sliding down a broad rock face like a curtain. What draws people here is the wide pool at the bottom that's easy to wade into — the water is cold and runs almost all year. Around it you'll find a rest area along with food and souvenir shops, so you can sit and eat right by the water.
Another thing that makes Sri Dit interesting is its history. Back in the day this was an area used as a forest base by the Communist insurgents (the Communist Party of Thailand). Traces remain, like a rice-pounding mortar driven by a waterwheel powered by the falls — you can walk over and see it while you take a break from swimming. It's a fall that gives you both a cool-off and a bit of a story.

- Entry fee — Adults 20 THB, children 10 THB

Before you get in at Sri Dit
The rocks around the falls are slippery, especially in the rainy season when the water runs hard. Water shoes or sandals with a heel strap are safer than going barefoot. Small kids should stick to the edge of the pool with an adult right beside them the whole time.

Than Thip Waterfall — easy walk, close to the road, still uncrowded
Than Thip Waterfall lies within Khao Kho National Park, on the Lom Sak district side. It's a single-tier rock fall, around 26 metres high and 30 metres wide, and the headwater of Huai Nam Khla. The water flows all year here too. The big draw is how easy the walk in is — it's not far from the road, and it's only a short stroll from the parking spot to the falls. That makes it a good fit if you'd rather not trek far into the forest, or if you're bringing older relatives and kids along.
Than Thip is a pretty fall that still doesn't see as many visitors as Sri Dit, so the atmosphere is quieter. It suits sitting and listening to the cool rush of water and taking photos more than a full-on swim. When the water runs strong, the park closes the swimming area for safety, so it's worth checking with the rangers at the entrance first.
- Location — Khao Kho National Park, Lom Sak district, Phetchabun
- Opening hours — Daily 08:30–16:00
- Access — Short, easy walk from the parking spot
- Water — Flows year-round; headwater of Huai Nam Khla
- Note — The park may close the swimming area when water runs strong; check at the entrance first
The opening hours differ slightly
Than Thip is inside the national park and closes earlier than Sri Dit (16:00). If you want to see both falls in one day, start at Than Thip in the late morning, then head to Sri Dit in the afternoon — that way you won't have to rush.
Other waterfalls around Phetchabun worth a stop
Beyond the two main spots, the Khao Kho–Lom Sak area has plenty more waterfalls and rapids scattered about. Most are smaller falls that look their best from the rainy season into early winter — good extra stops if you have the time.
Waterfalls in Phu Hin Rong Kla
Phu Hin Rong Kla National Park (on the Phetchabun–Phitsanulok border) has Rom Klao and Man Daeng waterfalls that look great in the rainy season — easy to fold into a trip with the Lan Hin Pum and Pha Chu Thong walks.
Nong Mae Na rapids and streams
The Nong Mae Na zone near Sri Dit has clear streams and small brooks where you can soak your feet and cool off. Shady and pleasant — good for a picnic.
Roadside falls along Khao Kho
On the climb up to Khao Kho there are several small falls right by the road, all clearly signposted, so you can pull over for a photo. They're not big swimming spots, but they're cool and pleasant.
When are Phetchabun's waterfalls at their best
- Jun–Oct (rainy season) — Plenty of water, strong flow, lushest green and best for photos, but the rocks are slippery and some spots may close to swimming when the water runs hard.
- Nov–Feb (early winter) — Water still flows well, the air is cool, and the water is clear — ideal for swimming and picnics. This is when crowds are biggest.
- Mar–May (hot season) — Sri Dit and Than Thip still have water since they flow year-round, and locals come here to cool off, though some of the smaller falls can dry up.
Pack for a swim
Bring a change of clothes, a towel, water shoes, and a waterproof pouch for your phone. Mountain waterfalls run colder than down on the plain, and small kids should wear a life vest. Take your rubbish back to a bin — many of these spots are inside national parks and we all need to look after them.
Plan a waterfall + Khao Kho trip
These falls already sit along the Khao Kho touring route, so they slot easily into a sea-fog-and-temple trip. This two-day route balances the waterfalls with the Khao Kho highlights.
