Namtok Kaeng Song

Namtok Kaeng Song is a broad rock-rapid waterfall on the Khek (Wang Thong) River, right off Highway 12 near Ban Kaeng Song village in Phitsanulok’s Wang Thong district — not the tall, plunging cascade the name sometimes suggests. A wide shelf of rock, roughly 150 metres across, breaks the river into rapids rather than a single dramatic drop, closer to a natural water park than a jungle trek destination.

The site has a suspension bridge for viewing the rapids from above, riverside restaurants and cafes, and tire-tube rental for floating the calmer stretches of the Khek River. It sits directly off the Phitsanulok-Lom Sak Road at roughly kilometre 45, with parking close enough that no notable hike is required to reach the water — a family-friendly roadside stop rather than a wilderness destination. Expect a modest entrance fee, around 40 THB for adults and 20 THB for children, collected locally rather than by Thailand’s national parks department.

Weekends draw local families for tubing and riverside meals; weekday mornings are quieter. Water flow peaks after the rains, roughly June through November, when the rapids run fuller and the tubing current picks up. It’s easy to confuse this waterfall with Namtok Kaeng Sopha further along the same highway — different site, different (higher) fee, since Kaeng Sopha sits inside Thung Salaeng Luang National Park while Kaeng Song does not.

Insider Tip: Rent a tire tube and float the calmer pools below the main rock shelf rather than just photographing from the suspension bridge — it’s the more memorable way to spend an hour here.

Watch out: The current picks up noticeably near the main rock shelf after rain, especially with kids in tow — stick to the calmer water downstream if the flow looks strong.

Bring sturdy sandals for wet rock, swimwear if you’re tubing, and cash for the tire-tube rental and food stalls. The free-flowing, easy-access setup makes this a reasonable half-day stop alongside other Phitsanulok attractions rather than a dedicated day trip on its own.
