Deadly

Khao Sok National Park is a funny kind of place. Due to it's relative proximity to Phuket / Khao Lak, the ability to use it as a stopover from these places to / from Samui ferry and being just one km from a nice highway, it see's it's fair share of tourists. So much so, that a village of lodges, minimarts, travel agencies and cafe's / restaurants has sprung up.

Besides the facts of access, the reasons for a visit include the entrance point to one of Thailand's biggest and most spectacular national parks, the impressive craggy scenery and deliteful meandering stream that finds it's way through the various bungalow operations. A poorly translated blog site names Khao Sok as no. 2 in Thailands list of top 10 national parks.

An acquaintance with the steamy jungle is on the cards. Khao Sok offers a number of trails, along some streams. Having done these trails already 20 years back, one would expect some improvement. But none of that. Though the village has expanded exponentially, the national park has little to show for 20 years of high entrance paying tourists. One is still leant on to take a guide to destinations just beyond a ninety minute walk over a 4WD track. Going beyond is forbidden without a guide, at least in the wetter half of the year. Such is the pressure that even to this point of return groups of tourists see themselves compelled to hire a guide which is ridiculous.

Though I might see some safety element in this, it questions why the same practice does not take place elders. Or why simply the trails are made safe enough for independent tourists. But maybe keeping the guide trade in business trumps all other reasons.

Anyway, mid 2011, we took the walk up the Khlong Sok as far as possible which leads to amongst a couple of swimming holes, the waterfall of Wang Hin. Wang Hin sits on a small tributary on the opposite bank of the main Khlong.

Beyond the Khlong, Wang Hin waterfall.

Further upstream are the waterfalls of Bang Leiap Nam and Ton Kloi, as well as Than Sawan which is up a side stream. Possibly a guide might be required for this waterfall

From the national park headquarters there is also the possibility to visit Sip-et-Chan waterfall, an eleven tiered waterfall (the translation already says it all). Possibly reachable during the dry season.

Other trekking destinations are the already aforementioned swimming hole (see photo of Bang Hua Raet below) as well as a few more spots for a dip.

Me, getting more wet with water than the customary sweat.

Just outside the national park there is the possibility for tubing (with guide), canoeing (with guide) or elephant trekking.

Over the mountains is the exceptional experience of where a major stream in the park has been flooded for hydropower usage. The lake level has risen enabling boot journeys around and among the towering limestone cliffs, a must-see.

Wang Hin waterfall of Khao Sok National Park is located in Surat Thani province, just over 100 km due west along the main 401 highway. Good and recent info on the park is available from Khaosok.com as well as from Khaosokdiscovery.com.

Probably some of the best independent users information comes from Tezza's beaches and islands extensive and updated entry on Khao Sok. He goes to considerable lengths to warn against leeches, I had only the one after 3 hours, which dropped off by itself and the bleeding terminated after a couple of hours.

The leeches contribute to Khao Sok being rated as the one of the World's Deadliest Places to Swim!

'Before you go camping in this national park, be advised. The area is the home to more deadly creatures than any naive tourist can imagine. Huge centipedes the size of an adult man’s arm, man eating sharks[!, there are none!], blood sucking leeches, giant mosquitoes and poisonous caterpillars and Scorpion fish. Getting bitten by leeches is seemingly unavoidable so make sure to take up smoking as leeches hate tobacco. When attacked, mix water with tobacco and pour it over the leech and it should let go. Whatever you do, do not try and remove it by force as it will cause it to release its venom'.

A better perspective to be had is from Thom Henley's Waterfalls and Gibbon Calls (2005).

A lot of Calamus

Heading south from Mae Sot towards Thailand's wild west capital of Umphang, there are a few opportunities to visit some waterfalls. One of which is the often visited Pha Charoen waterfall located in the national park of the same name.
However as one also has to return via the same road there's another opportunity to visit a waterfall in the same national park without everybody being stressed out about yet again a waterfall.

Pa Wai (or Ba Wai) waterfall is well signposted off the Umphang - Mae Sot highway no. 1090 though the distance from the highway is not the announced 9 km rather double. Access is south of Phop Phra district around km 40.


Apparently the name of the waterfall is derived from the plant of the same name (Calamus Caesius, rattan, see also below).

There aren't many facilities other than a toilet and a shelter, though there are a couple of makeshift bridges.

In reality the stream falls over a great many steps amounting to a fall of around 40m. As the steps are small and wide there are many trees in-between giving the area something special, though there is no big pond at the bottom of the falls, there are a number of steps to splash around in.


On the other side there is a deep sink hole (see photo above) where a part of the stream falls in, only to reemerge at the foot of the cliff. there is also a cave for those visitors fortunate enough to have a torch on them all the time. And a large tree at the bottom of the cliff.

The official Thai Department of National Parks website there is this about the waterfall:

'Bawai [Pa Wai] waterfall is a 100-step limestone waterfall, originating from Huai Wai with the flowing water throughout the year. The Waterfall is situated in virgin forest consisting of medium-sized/large plants. The Waterfall is called “Bawai Waterfall” because there are a lot of Calamus Caesius within the area'.

From wikitravel:

'To admire this waterfall, one must walk from its ground floor to the upper level. Then, go further for around 30 m, visitors will see a channel of about 10 m wide where flowing water falls and disappears under the mountain base. The waterfall originates from Pa Wai Creek where water flows all year round and many rattan plants grow. It is therefore named ‘Pa Wai’, which means a rattan forest'.
