Klong Yai Kee Waterfall sits toward the north-western side of Koh Kood, in Koh Kood District, Trat Province, set back in the forest off the main road. The falls themselves are a rock face around 5–6 metres high, but what people like is that the water doesn't drop in a single sheet — it runs down a run of stepped rock ledges, like a staircase, into a wide pool at the bottom shaped a bit like a big bowl. The water is clear and cool, flowing through thick jungle, and it's quiet enough that you mostly hear just the water and the birds. A lot of people say that calm is the real charm of Koh Kood.
Why people pick Klong Yai Kee over Klong Chao
Klong Chao is the biggest and most famous waterfall on the island, and during high season some days it gets fairly busy, especially from mid-morning into the afternoon. Klong Yai Kee is further in, with fewer signs pointing the way, so it tends to stay quieter — plenty of times you'll arrive and find just your own group or a handful of other people. If your goal is to photograph a nice waterfall without people walking through the frame, or to soak quietly in the pool, Klong Yai Kee does it better.
- Fewer people — it's set back with few signs, so many skip it, which keeps it quieter than Klong Chao almost any time of day.
- Multiple rock tiers — the water steps down ledge by ledge, and it photographs better than you'd expect for a falls only a few metres high.
- A pool you can get into — the bottom is a wide pool deep enough to soak in, and at times there's a rope rigged up to swing and jump off into the water.
- Short walk in — it's a not-too-long concrete staircase down from the parking area, good for anyone who doesn't want a hard jungle hike.

What's the trail like — is it a long walk?
Good news: the walk is short and not brutal. From the car park, a concrete staircase leads down into the forest, around 300–400 metres, an easy 10 minutes or so to the stream. Near the end before the falls there are some big boulders to scramble over for a few moments. The way down is fairly steep, and some sections of the stairs get slippery if it's just rained, so wear shoes with decent grip — don't go down in slick flip-flops. On the way back you climb the same stairs, so anyone with dodgy knees might find it a little tiring, though it's not too rough.
Timing tip
Go early in the morning for the best light and the fewest people. Plenty of folks who went mid-morning found it quiet; go early and it's even quieter, almost like having the waterfall to yourself, and the sun isn't fierce yet so climbing back up the stairs is easier.
Can you swim — how deep is it?
Yes, you can. The pool at the bottom is clear, cool, and deep enough to actually soak or paddle around in, and at times there's a rope tied up to swing and jump off. But how deep the pool is depends on the water level that time of year, so before you jump you should get in first and check that the spot is genuinely deep and free of submerged rocks. The water here is fresh water from the forest headwaters, a good deal colder than the sea — if you feel the cold easily, brace yourself a little.
- Water level by season — from the rainy season into early winter the water is high, flowing strong, and at its best. By late dry season (Mar–Apr) it drops, the pool gets shallower, and some years it's down to a still pool.
- Check before you jump — the pool isn't the same depth everywhere or every season; don't jump from the rope until you know how deep that spot is.
- Slippery rocks — the rocks around the pool are mossy, so walk slowly and hold on firmly, especially scrambling over the boulders near the end.
- Pack out your trash — there are no bins and no shops at the falls themselves, so bring a bag and carry your rubbish back out.
How to get to Klong Yai Kee Waterfall
The easiest way is to rent a motorbike and ride there yourself. The roads on Koh Kood are paved almost the whole way, but they're narrow, climb and drop over steep hills, and have a lot of bends. From the Klong Chao Beach area, which is the main accommodation zone, head north past the hospital/police station, then turn off following the signs for Klong Yai Kee Waterfall. There's a parking area near the trail down. At the trailhead there's a small shop (people call it the coconut shop / Mr & Mrs Coconut) where you can grab drinking water before heading down.
- Motorbike rental — around 200–300 THB/day, the most flexible way to get around the island. But the roads are narrow and steep, so first-timers should ride extra carefully and always wear a helmet.
- Car with driver / resort transport — if you're not comfortable riding yourself, many resorts offer pickup service or run waterfall tours.
- Pair it with Klong Chao Waterfall — the two falls are in different zones but you can do both in a day. Start at Klong Yai Kee in the morning while it's quiet, then head over to Klong Chao.
Straight talk on getting there
Koh Kood is far out — you have to take a boat from Laem Sok / Laem Ngop pier in Trat, around 1–1.5 hours, and during the monsoon (roughly May–Oct) the swell is strong, some boat runs are cut or cancelled, and many places to stay close for the season. Check the boat schedule and book your accommodation ahead. Food and supplies on the island also cost more than on the mainland, and phone signal and power are limited in some spots, so plan with a bit of slack.
Entry fee and facilities
Klong Yai Kee Waterfall is free to enter — there's no admission fee (there may be a small parking fee at times). But at the falls themselves there's no real restaurant or proper toilet, just a small shop at the trailhead selling drinking water, so bring your own water, snacks, and essentials, and carry your trash back out to bin it outside.
Klong Chao Waterfall
The island's biggest and most famous waterfall, with a wide pool for swimming. It's busier but easier to reach, and you can pair it with Klong Yai Kee in a single day.
Klong Yai Kee Beach
A small, quiet beach in the same zone, across from Captain Hook Resort. It's fairly hard to reach, so it suits people who really want peace and quiet.
Giant Tree (Giant Makha Tree)
A huge old tree in the middle of the Koh Kood jungle, in the inner zone near the road to Ao Salad. Worth a photo stop while you're out at the waterfalls.
Getting ready for Klong Yai Kee
- Shoes with good grip — the stairs and rocks get slippery, especially after rain. Skip the flip-flops.
- Water + snacks — there's no shop at the falls, so stock up at the trailhead or bring some from your accommodation.
- Mosquito/insect repellent — it's thick forest with a few mosquitoes, so bring repellent.
- Dry bag — for your phone, camera, and valuables, to keep them dry while you scramble over rocks and swim.
- Go early — fewer people, nicer light, and you avoid climbing the stairs back up in the blazing sun.
