Tham Lod sits in Tham Lod sub-district, Pang Mapha, about 8 km from the district town. It lands almost exactly halfway between Mae Hong Son town and Pai, so anyone driving Route 1095 (Mae Hong Son–Pai–Chiang Mai) can easily pull in. The cave runs close to 1,600 metres, with a clear stream flowing down the centre — which is what gives it a way of touring you won't find in any other cave in Thailand: you ride a bamboo raft with the current rather than just walking the whole way.
What's Inside Tham Lod — Three Caverns in One
Once you've paid for the raft and hired a guide, the guide carries a pressure lantern and leads you through one chamber at a time. The cave splits into three sub-caverns, each with a clearly different character. Doing all three takes roughly 1.5–2 hours.
Sao Hin Luang Cavern (Great Stone Pillar)
The first cavern you reach: an open hall with a high ceiling and a colossal stalagmite-stalactite column rising in the middle. Some say a few of these are among the tallest in Southeast Asia. Shine the lantern up and you'll catch mineral crystals glinting back.
Tukkata Cavern (Doll Cave)
The widest and longest of the three. It gets its name from rows of small knobby stalagmites lined up like tiny dolls standing in a queue. You climb a wooden staircase to an upper level — this is where the rock formations are at their finest and most detailed.
Phi Man Cavern (Spirit People — inner Doll Cave)
The final cavern, and an archaeological site. Pottery shards, plant seeds, stone tools, and ancient human bones have been found here. The standout is the ancient wooden coffins — the 'Spirit People coffins' — that have rested on a stone ledge for a thousand years and more.

The Bamboo Raft — What Makes This Cave Different
A clear stream runs down the centre of the cave for nearly 300 metres. On the way in and out you ride a bamboo raft poled along by a standing boatman, while in the middle you step off and walk a wooden boardwalk up to the upper cavern before getting back on a raft on the far side. Poling through pitch black with nothing but lantern light to lead the way, plenty of people say it feels like slipping into another world. The water is so clear you can watch big mahseer fish swimming alongside the raft.
About the water in the rainy season
During the rains (May–Oct) the water level inside the cave rises. On some days the raft can't make it into the inner cavern and parts get closed off temporarily. If you want to raft the whole stretch and get good photos, aim for Nov–Apr, when the water is clearer and calmer.
The Ancient Spirit People Coffins — The Real Thing, Over a Thousand Years Old
'Spirit People' (Phi Man) is the local name for the ancient wooden coffins found scattered across high caves throughout Pang Mapha. Each is a large log hollowed out down the middle like a canoe, with a carved head at either end, used to hold the bones of the dead from prehistoric communities. Archaeologists date them to roughly 1,200–2,200 years old. At Tham Lod you can still see the coffins resting on the stone ledge in the Spirit People cavern — the real thing, not replicas. It's a rare piece of heritage that deserves to be seen with respect: no climbing on them and no touching.
The Evening Swift Flocks — Free to Watch
Around sunset, roughly 5.30–6.30 pm, hundreds of thousands of swifts pour back into their roost in the cave all at once, forming a long black ribbon across the sky — passing the bats heading the other way to feed. It's a spectacle you can watch for free from the cave mouth, no raft fee required. Plenty of people time their visit for the evening just for this. Find a spot near the bridge in front of the cave before it gets dark.
Prices, Opening Hours, and What to Know
- Opening hours — roughly 8.00/9.00 am–6.00 pm daily. If you're there for the evening swifts, arrive before 5.00 pm.
- Lantern guide fee — around 150 THB per group (a guide is mandatory; you can't go in on your own). One guide looks after about 3 people.
- Bamboo raft fee — around 300–400 THB per raft, seating 3–4 people (you can choose all 3 caverns or just 2), plus a 20–30 THB per-person cave maintenance fee.
- Total for a small group — works out to about 450–550 THB per raft. Split between 3–4 people, it's good value.
- Walking all 3 caverns — takes about 1.5–2 hours, with a fair bit of wooden-staircase climbing.
Tips before you go
Wear shoes that can get wet and won't slip, since you'll be stepping onto the raft and walking on damp rock. Bring a backup flashlight or your phone even though the guide carries a lantern, and have cash ready to pay — signal and card-payment options are limited out here.
How to Get to Tham Lod
The easiest way is to drive yourself or rent a motorbike, since the cave sits right off Route 1095 between Pai and Mae Hong Son. If you don't have a vehicle, you can take a songthaew or minivan on the Pai–Mae Hong Son line and get off at the Tham Lod turn-off in Pang Mapha, then catch a motorbike taxi the remaining 8 km or so. Or just buy a half-day tour from Pai with transport included.
From Pai
About a 1-hour drive (~50 km) on Route 1095 toward Mae Hong Son. Most people do Tham Lod as a half-day trip out of Pai.
From Mae Hong Son town
About a 1.5-hour drive (~70 km) on Route 1095 toward Pai. A good stop to make while running the Mae Hong Son–Pai–Chiang Mai loop.
How to Do Tham Lod — Plans Based on Your Time
Tham Lod sits right in the middle of the route, so you can stop in while running the loop or make it a half-day trip from Pai. Here are the two ways people usually do it.
