Suan Hin Pha Ngam — officially Hin Pha Ngam Forest Park — sits at Ban Pha Ngam, Puan Phu subdistrict, Nong Hin district, Loei province. It's a wide limestone forest spread over thousands of rai, where nature has slowly eroded the rock into tall columns and pillars standing in strange rows. Loei locals nicknamed it the Kunming of Loei because it looks like the famous stone forest in Kunming, China. What sets it apart from your average nature spot is that you actually walk into the gaps between the rocks — you don't just stand outside and look.
Why they call it the Kunming of Loei
The rock formations here come from ancient limestone hills worn down by water and wind over ages until they split into grooves, columns and narrow gaps. Some pillars tower several metres overhead, and walking in among them feels like stepping back into prehistoric times. All around is a wide meadow that turns vivid green in the rainy season, contrasting beautifully with the grey of the stone. People who've been say the same thing: this corner photographs like somewhere overseas, and that's exactly why the Kunming of Loei nickname has stuck for so long.
- Tall limestone ridges — columns of rock standing in long rows, some several metres high and well over head height.
- Green meadows around the stone forest — in the rainy season the grass turns deep green and contrasts especially well with the rock.
- Oddly shaped rocks — some people call one the giant turtle rock; others look like animals or objects, depending on your imagination.
- Narrow maze-like gaps — the paths twist and turn, left then right, until you can barely keep track of the way.

What walking through the rock gaps is like
The real charm of Suan Hin Pha Ngam is in the walking, not the standing and looking. The trail through the stone forest twists and turns like a maze — some stretches are narrow gaps where you walk single file, others have you ducking under rock ledges or climbing over boulders to the next level. It's fun in a way that takes some effort; this is not a smooth, easy path. The full loop isn't very long, but because you're climbing and ducking the whole time, it takes around one to two hours depending on how long you stop for photos. To be honest, if your knees aren't great or you don't like tight spaces, you may want to stick to the sections you can manage.
Why you'll want a guide
The paths through the stone forest are genuinely complicated, and not every junction has a clear sign. Wandering in on your own, it's easy to get lost and waste time. The forest park has staff and local guides on hand — you can arrange one at the visitor centre by the entrance. The guide takes you along the prettiest, safest route and tells you which rock looks like what. It's well worth it compared to going in solo.
Entry fee, guide fee and opening hours
Entry to Suan Hin Pha Ngam is charged per group, not per person, so if you go with several people it works out cheap. The prices below are what's actually collected on site, but they can change with the season. Bring enough cash, because this is out in the forest — many spots have no signal and don't take transfers.
- Guided tour (guide included) — around 100 THB per group (groups of up to roughly 10 people).
- Local shuttle fee — around 30 THB per person (in some cases a vehicle takes you to the trailhead).
- Opening hours — roughly 08:00–17:00 daily. Going in the morning is best: it's cooler and you have plenty of time to walk at an easy pace.
- Walking time — around 1–2 hours per loop, depending on how long you stop for photos.
When it looks its best
Suan Hin Pha Ngam has a different charm each season. The stretch most people love is the rainy season into early cool season, roughly July to November, when the meadows all around turn deep green and contrast especially well with the grey of the stone, and the weather isn't too hot. In the hot season the grass turns brown and the sun is harsh, so the walk is more tiring, but it's still doable. One thing to watch: on a day when it has just rained, the rocks get slippery, so walk with extra care — shoes with good grip will keep you safer.
How to get to Suan Hin Pha Ngam
Suan Hin Pha Ngam is in Nong Hin district in the southern part of Loei province. From Nong Hin town you turn off and drive about 18 km more along the road to Ban Pha Ngam. The last stretch is a rural road, but a regular sedan can make it, and the turn-off is clearly signposted. Going by your own car is by far the easiest, since public transport barely reaches here.
- From Loei city — drive south toward Nong Hin, around 50–60 km in total, about an hour.
- From Chiang Khan — drive down through Loei city; about an hour and a half to two hours.
- From Nong Hin town — turn off toward Ban Pha Ngam for about another 18 km.
- Public transport — hard to reach; a private car, rental, or chartered ride from town is recommended.
Get ready before you walk
Wear sneakers or hiking shoes with good grip — flip-flops aren't recommended since you'll be climbing on rock. Bring drinking water, a hat or sun umbrella, and sunscreen; some sections have no shade. If you're bringing small children or older relatives, tell the guide ahead of time so they can pick an easier route.
Suan Hin Pha Ngam vs. other nature spots in Loei
Loei has all kinds of nature spots, from high peaks and seas of mist to stone forests. If you're wondering how Suan Hin Pha Ngam stands apart, the short answer is that you get to walk an adventure through real rock gaps — not just go up and shoot a view. Have a look at the table comparing it with other spots in the province to help plan.
Suan Hin Pha Ngam (Kunming of Loei)
An oddly shaped limestone forest in the middle of a meadow. Walk through the rock gaps, duck through hollows and climb over ledges like a maze, with a local guide leading. Fun in a hands-on way — great for anyone who likes an active hike.
Phu Pa Po (Fuji of Loei)
A viewpoint over the triangular Phu Hor, which looks a bit like Mt. Fuji, with a sea of mist at its base. You ride up to the top on the villagers' farm tractors. It's also in Nong Hin, so you can pair it with Suan Hin Pha Ngam in a single day.
Phu Thok (Chiang Khan)
The closest sea-of-mist viewpoint to Chiang Khan town. You ride up by songthaew and watch the mist over the Mekong in the early morning. Easy to reach and not tiring, good for first-timers, and in a different zone from the stone forest.
Phu Ruea National Park
You can drive almost to the summit, then walk on to the sunrise viewpoint. In the cool season it gets bitterly cold and has even had frost, with wide rock-terrace views. It's in another zone of the province, good to fold into a separate day of the trip.
A sample Nong Hin itinerary, starting at Suan Hin Pha Ngam
Suan Hin Pha Ngam is in Nong Hin district, which has several other nature spots, so you can easily turn it into a two-day, one-night trip from Loei city. Take a look at this plan and adjust the timing to suit you.

Honest word before you go
Suan Hin Pha Ngam is most fun for people who like to walk and don't mind getting tired. If you're expecting an easy, chilled-out spot for relaxed photos, it may not quite be your thing, since there's a fair bit of climbing and ducking. In the hot season the sun is harsh and the grass isn't green, so it looks less striking. It's a forest spot where the phone signal is weak and there are no convenience stores, so bring your own water and snacks.
