Namtok Karom

Namtok Karom marks the Khao Luang National Park headquarters, established in 1975 in Khao Kaeo subdistrict, Lan Saka district — a working ranger station and campground as much as a waterfall stop. The falls drop through 19 separate tiers down the flank of Khao Luang, though only the lower seven are open to visitors; a signed 1-km path from the car park leads to the main pools, wide and well maintained enough to walk in trainers during the dry months.

Entry costs 200 THB for foreign adults (100 THB for children), 40 THB for Thai adults (20 THB for children), plus a small vehicle fee — 20 THB for a motorcycle, 30 THB for a car. That surprises some visitors, since community-run waterfalls elsewhere in the south are often free; Namtok Karom sits inside a national park boundary, so the standard Department of National Parks fee applies. Gates open at 6am and close at 6pm daily.

The lower pools are broad and shallow enough for casual swimming, shaded by dipterocarp forest that keeps the approach walk cool even at midday. Flow is heaviest from October to January, when the northeast monsoon soaks this side of the peninsula — the same rains that flood low-lying Nakhon Si Thammarat most winters — and thins out by April, when the upper tiers can reduce to a trickle. Weekday mornings are quiet; weekends bring Nakhon Si Thammarat families with picnic mats and coolers, especially around the lower pool nearest the car park.

Insider Tip: Ask the ranger booth about conditions above the seventh tier — trail access beyond it depends on recent rain and can close without notice, but rangers usually know which upper pools are worth the extra scramble that week.

Watch out: Rocks around the pools get slick with algae once the water’s running hard; the path itself is fine in trainers, but skip the wet rocks in flip-flops.

The waterfall sits roughly 9 km from Ban Khiri Wong, the village most visitors use as a base for treks higher up Khao Luang — a reasonable stop if you’re already in the area for the mountain, rather than a stand-alone day trip from Nakhon Si Thammarat town.
