Thailand's southern province of Chumphon is not well known touristically, not for it's superb beaches, nor for the beautiful forests containing possibly some great waterfalls.
That said there's not a tourist website that fails to mention the existence of Kapo (Kapoh) waterfalls, to the northwest of the province's capital.
Though why this figures as the most mentioned of this province's waterfalls beats me.
The waterfall is easily accessible from the main highway (no. 4) going south via a very poorly signposted trail. Blink and miss. The access road brings you to a grassy plateau, none of which might give you a clue that you had arrived already. Continue onwards the black top runs out and you end up on a T crossing. Way too far!
The waterfall is near the grass plateau, travel back. Park the car and visit the hardly discernible waterfall.
Apparently somewhere in the past, much effort had been invested in making this a recreation park, but no funding reserved for maintenance.
The 'fall' is a 2 m drop followed by a couple of short drops into a stagnant pool. Due to the fact that this waterfall is near to the highway the effort to pull the car over from chugging down the highway is quite easy. But expectations should be tempered, maybe stock up at a petrol station and have a picnic.
Most web sites refer as follows:
'Located in Tambon Salui, this waterfall is 13 kilometres from Tha Sae, along Phetkasem Road, between 466th 468th kilometre, or from Pathomphon Crossroad, by Petkasem Road for about 30 kilometres. The park has the area of 7,010 Rai of shaded forests and small waterfalls, suitable for relaxation' (source).The Bangkok Post adds:
'It is a pleasing dappled park with a small waterfall and many species of plants appropriate for natural science study and relaxation'.Kohtaotoday puts the following description:
'The park has a pleasant atmosphere of cool forest with a small waterfall flowing. All year round. There are many kinds of the plants, the residents of some birds kinds of the animals. This park is suit able for relaxation'.
