Most guests staying in Kathu have no idea there's a proper jungle waterfall a ten-minute drive from the front gate. It's not Niagara — nobody's pretending — but it's a genuine forest walk with a swimmable pool at the top, and on a hot afternoon it's a useful alternative to another beach run. If you're staying at our unit at Dcondo Creek and want a half-day that isn't a mall or a sunbed, this is the easy answer.
The trail itself
Kathu Waterfall (น้ำตกกะทู้) has three tiers. The first sits right at the entrance — a small cascade you can see from the car park, often crowded with families taking photos. The walk that's actually worth doing goes up to the second tier, which is where the pool is and where most people turn around.
It's about 20 minutes up, 20 minutes back down — call it 40 minutes round trip if you don't stop. The path is concrete steps and packed earth for the first stretch, then rougher stone and tree roots higher up. Trainers are fine. Flip-flops will work if you're careful, but you'll regret them on the way down if it's been raining.
Things to know before you go:
Bring water. It's humid under the canopy and there's nothing to buy past the entrance.
Mosquito spray is worth it, especially late afternoon.
Swim gear if you want to get in at the second tier. The pool is shallow and cold — pleasant rather than dramatic.
The third tier exists but the path gets sketchy and the reward isn't huge. Skip it unless you're a serious walker.
When there's actually water
This is the part most blogs skip. Kathu Waterfall is seasonal. In February, March and early April it's often just a trickle — you'll walk up to a damp rock face and wonder what you came for. The waterfall starts moving properly once the early rains arrive, usually mid-to-late May, and runs strong through the green season into November.
If you're here in the dry months and still want to go, the walk itself is still pleasant — shaded, quiet, full of butterflies — just adjust expectations. If you're here May through October, this is when the place earns its name. After a heavy overnight rain, go the next morning.
Getting there and parking
From Dcondo Creek it's about 3.5 km, roughly 10 minutes by scooter or Grab. Head up Wichit Songkhram Road, follow the brown signs for Kathu Waterfall, and you'll hit a small car park at the end of a residential lane. Parking is free. There's usually an attendant pointing you to a spot.
Entry to the waterfall itself is free. There's no ticket booth, no gate, no official opening hours — though in practice you want to be walking before 4pm so you're not coming down in fading light.
The noodle stop on the way out
Right by the car park there's a small open-air noodle shop — a few plastic tables, a lady with a wok, a menu mostly in Thai. They do a solid guay teow (Thai noodle soup) and a decent pad see ew for under 80 baht. It's the obvious stop after the walk: you're sweaty, you're hungry, and it's right there. Cash only, and they close when they run out, so earlier is better.
If you want a bigger sit-down lunch instead, you're five minutes from the Kathu town strip and a short drive from everything around our Kathu guide.
Worth it?
For half a morning, yes — especially in green season, especially if you've been doing beach days and want trees instead of sand for a few hours. It's not a destination you fly to Phuket for. It's a good local walk that happens to be ten minutes from where you're already sleeping, and that's the whole point.
