How difficult is the trail — is it suitable for beginners?

The route covers 16 km round-trip over two days and one night, requiring extended stream wading with sections up to waist-deep, plus steep rope-assisted climbs. If it rains, difficulty increases two to three times, making it unsuitable for inexperienced trekkers.

Is there any phone signal along the trail?

There is no mobile phone signal of any carrier from the trailhead all the way to the waterfall and back.

How do I book, and what vehicle is needed to reach the trailhead?

You must call the Khlong Naka Wildlife Sanctuary directly during office hours to make a booking. A 4x4 vehicle transfer to the trailhead is required and costs 700 THB per vehicle.

Are rangers present throughout the trek?

Yes, the sanctuary assigns one ranger per two visitors for the entire route, with a lead guide and team accompanying the group from front to back throughout the trek.

How many camp zones are there, and can I choose my own?

There are three camp zones, all near the stream and each with basic toilets, but rangers assign campers to a zone — you cannot choose your own. Camp 1 is the largest and fits tents and hammocks; Camp 2 is 400 m further with hammock frames; Camp 3 is roughly 200 m past Camp 2, near the stream crossing to the waterfall.

Nam Tok Sai Rung La-ong Dao

Ranong

4.6(10 reviews)

Nam Tok Sai Rung La-ong Dao is a deep-jungle waterfall reached by a grueling 16 km round-trip trek through Khlong Naka Wildlife Sanctuary, making it one of the most demanding camping in Ranong province. The trip runs over two days and one night, with the first 6 km being mostly stream wading — sections can reach waist depth, and rain raises the difficulty two to three times over. Rangers accompany every group at a ratio of one officer per two visitors throughout the entire route, and there is no mobile phone signal from start to finish. Three camp zones are available near the stream, each with a basic toilet; camp assignment is decided by staff, not visitors. After setting up camp, hikers push a further 2 km to the waterfall itself, climbing from 200 m to 450 m elevation in just 1 km before a steep rope-assisted descent. Entry fee is 40 THB per person; guide, porter, and 4x4 transfer fees are charged separately. Advance booking by phone is required.

Notes from our team

Who it suits: Reaching the waterfall is a real jungle trek: you cross the river several times, wade through water, and handle slippery rocks and very steep sections — about 7 km taking around 6 hours. This spot suits fit, experienced adventurers far more than families with small children or elderly members.
