Thailand’s beaches get the attention. Its waterfalls are, for our money, the better day out — cool, green, mostly empty, and free of anyone trying to sell you a boat trip.
Here are nine worth the drive, with honest notes on the walk, the fee, and — crucially — the months each one is actually worth visiting.
Quick picks
- Best overall: Erawan, Kanchanaburi — swimmable, jade-green, year-round
- Best with small children: Phlio, Chanthaburi — flat, shaded, gentle
- Best if you hate crowds: Huay Mae Khamin, Kanchanaburi
- Best real adventure: Thi Lo Su, Tak — remote, enormous, rainy-season only
- Best month across the board: August–October
1. Erawan Waterfall, Kanchanaburi
≈2.5 hrs from Bangkok · ฿300 foreign adult · easy to moderate · year-round
Seven tiers of limestone pools stepping up a jungle hillside, each a different shade of green, and you can swim in most of them. It’s the most famous waterfall in Thailand and it earns it.
How hard: Tiers 1–3 are an easy flat walk on a paved path. Tiers 4–5 involve some scrambling. Tiers 6–7 are a proper hike with roots and rock, and are consequently almost empty — most visitors stop at tier 2.
Why it works year-round: it’s spring-fed through limestone, so the pools stay that extraordinary colour even in the dry season when other falls have stopped.
Practical: Water shoes if you have them — the rock is slick. The little fish nibble your feet. Rangers stop entry to the upper tiers in mid-afternoon, so start early. Full Erawan guide →
2. Phlio Waterfall, Chanthaburi
≈3.5 hrs from Bangkok · ฿100 foreign adult · easy · best Jun–Nov
A shaded, flat, ten-minute walk through forest brings you to a gentle waterfall and a large clear pool swarming with soft-shelled turtles and fish. There’s a curious white stone chedi beside it, built by King Rama V in memory of his queen.
The single best Thai waterfall for young children — no scrambling, plenty of shade, and the turtles reliably delight everyone. Combine it with Chanthaburi’s riverside old town, which is one of the most surprising corners of the country. Full Phlio guide →
3. Huay Mae Khamin, Kanchanaburi
≈4 hrs from Bangkok · ฿300 foreign adult · moderate · best Jul–Nov
Erawan’s quieter twin: also seven tiers, also beautifully swimmable, and with a fraction of the visitors because it’s another 90 minutes down the road past a reservoir. If Erawan’s crowds put you off, this is the answer.
Practical: Really an overnight from Bangkok, or a day trip if you’re already staying in Kanchanaburi. The last stretch of road is rough.
4. Haew Narok, Khao Yai
≈2.5 hrs from Bangkok · ฿400 park entry · moderate · best Aug–Oct
The tallest waterfall in Khao Yai — a three-tier plunge of about 150 metres into a gorge, viewed from platforms. No swimming here, and the barriers exist for good reason.
Pair it with Haew Suwat, the more famous fall in the same park (the one from the film The Beach), which does have a swimmable pool below it in the right season. Khao Yai guide →
5. Mae Ya, Chiang Mai
≈1.5 hrs from Chiang Mai · ฿300 park entry · easy · best Aug–Nov
In Doi Inthanon National Park, and one of the tallest in the country — 260 metres of water fanning out across a wide, stepped rock face rather than a single drop. Photogenic in a completely different way from Erawan’s pools.
Practical: Combine with Doi Inthanon’s summit, the twin royal pagodas and the Karen village markets for a full and genuinely excellent day out of Chiang Mai. Chiang Mai guide →
6. Thi Lo Su, Tak
≈7 hrs from Bangkok, then a 4WD track · ฿200 · hard to reach · Aug–Nov only
The big one. Roughly 250 metres wide and 300 metres high in Umphang Wildlife Sanctuary, near the Myanmar border. Genuinely one of Southeast Asia’s great waterfalls, and almost no foreign visitors see it.
Be realistic: this is a multi-day expedition, not a day trip. The road in is closed or impassable outside the rainy season, which is also exactly when the falls are at full thunder. Most people combine a rafting trip with a night in Umphang.
7. Khlong Lan, Kamphaeng Phet
≈5 hrs from Bangkok · ฿200 foreign adult · easy · best Jul–Oct
A wide 100-metre curtain of water falling into a large pool, with a five-minute walk from the car park. Very rarely visited by foreigners despite being one of the most photogenic falls in central Thailand. A good stop if you’re driving between Bangkok and Chiang Mai.
8. Namtok Phliu-area falls, Eastern Thailand
≈3–4 hrs from Bangkok · ฿100–200 · easy · best Jun–Nov
The eastern provinces — Chanthaburi and Trat — are full of small, uncelebrated waterfalls that local families visit at weekends with a picnic and nobody visits during the week. Not spectacular individually; collectively, a lovely way to spend a day somewhere very few visitors go.
9. Sai Yok Noi, Kanchanaburi
≈2.5 hrs from Bangkok · free · easy · best Aug–Oct
Small, right beside the Death Railway line, and free — which makes it the easy add-on to a Kanchanaburi day rather than a destination in itself. Nice shallow pools for a cool-off, and busy with Thai families at weekends.
When to go
| Months | What you get |
|---|---|
| Aug – Oct | Peak flow, everything green. The best window by far. |
| Nov – Jan | Good flow, cooler air, comfortable walking, dry paths. |
| Feb – Apr | Many falls reduce to a trickle. Erawan still worth it; most others aren’t. |
| May – Jul | Building back up. Fine, not peak. |
The exception is anything limestone and spring-fed — Erawan above all — which holds its colour and volume through the dry months.
What to bring
- Cash for the gate; card machines are rare
- Water shoes or old trainers — wet limestone is genuinely slippery and flip-flops are useless
- A dry bag for phone and wallet
- Insect repellent, especially late afternoon
- A towel and a change of clothes — you will get in
- Your own water and snacks for the smaller parks
Two things worth knowing
Foreign-visitor pricing is normal. Thai national parks post two rates, and the foreign rate is higher. It’s official policy, it’s displayed at the gate, and it isn’t someone overcharging you.
Waterfalls close earlier than parks do. Rangers often stop entry to upper tiers from mid-afternoon so nobody is coming down in the dark. If you arrive at 3pm you may only see the bottom two levels. Arrive by 10am.
Most of Thailand’s best waterfalls sit inside national parks reached by winding roads with no useful public transport, and the sights within each park can be kilometres apart. A private van with a driver who knows the routes turns a logistics puzzle into a very good day.
