Zilch

The trail
One of Thailand's better known hot springs is the hot spring of Mae Kasa, located at the foot of the mountains separating Mae Sot district from the rest of central Thailand's Tak province.

Despite it's prominence there is still some difficulties in finding the soak site. First one steers up the highway 105 to the north of Mae Sot until km 13/14 where one goes through a big gate and then continues onwards to the village of Mae Kasa, 7 km's away.

In the village directions to the hot spring stop and one needs to find one's own way to the other side of the village where the road continues. The hot spring is located about a km out of the village. The main site is down a dirt road on your left, though there are some springs visible on the right but these are for some reason off-limits, there's a big fence around them. Driving down the dirt road one comes to a rudimentary parking below a dam which seems to dam the adjacent stream to create a lake for ecstatic (?) reasons.

Are those eggs boiled yet?

Bubbly
From the parking area one can see what's the highlight of this soak site, a bubbling hot spring which one can walk around. Two girls are trying to boil eggs directly in the spring; as it transpires the only springs related activity on offer.

We gather our soaking stuff and confidently walk up to the surrounding buildings, seeing that there was a large pond empty. Unfortunately whatever the purpose was of these buildings, they are now in open season for vandals and miscreants to plunder and spoil. There is no way to soak at this hot spring!

Possibly sometime last century this was the soak site ...

And that seems to contrast with the vibrant feeling of the direct hot spring site. There are about 2 dozen other visitors who are all hanging out at the shops / bars surrounding the parking area. Possibly this is the best place to relax in this area?

The cave? Waterfall?
Somewhere I read something about there being a waterfall and because of the lay of the land, it has to be upstream. We climbed up the side of the dam to see the recently dammed lake. There's a makeshift temple on an island in the center which can be reached by a rickety swing bridge.

Beyond the temple is more parking place and a surprisingly well maintained track, well for 5 meters that is. After that deterioration sets in and the couple of bridges across the dry stream have all been set alight some time in the past, I seem to be getting an idea about what kinds of past-time are hot here.
Halfway up a very steep track we give up, it doesn't seem to be leading anywhere and is not used often anymore.

I later learn that one could continue onwards to a mouth of a cave over which a small stream falls, but seeing there's no stream there's also no waterfall or is that such a weird idea?

Andy Daniels adds

'After looking around at the cool hot springs area I decided to walk up a trail/staircase that went up to a budhist cave. The trail was long and pretty steap. After talking to my dad, who called me while on the trail, I continued to walk and a guide with some monks said he could show me the cave for 300B or else it was locked closed. I told him I would not pay that and would just see what I could see. Thats what I did, the cave was pretty cool but I didn't go too far in, and was happy with what I saw'.

No waterfall even though websites such as wikitravel proclaim the following:

'This large waterfall is located in Tambon Mae Kasa. There is a path leading the way up to a high mountain. A cave in front of the waterfall has a 5 m wide stream of water which serves as an entrance to the waterfall'.

Thailandcaves adds that there are

'... over 850 steps to ascend to entrance, but the cave is impressive. A series of large chambers descend steeply to a large passage which leads to a pool of water where the tour stops. Wading the shallow pool gices access to around 100m of muddy passage that eventually chokes'.

There are also a number of photo's of the cave. But none of the waterfall ...

Other experiences
The official wikitravel entry (undated) on Mae Kasa hot springs goes as follows:

'This hot well of 2 m wide is located in Tambon Mae Kasa, right in the village. Hot and cool streams flow to meet at this well. Visitors can smell sulphur throughout the village and see slight vapour just above the ground. At an edge of the well, the water is easily seen boiling and its temperature is fairly high. A private room for mineral bathing is available. The village is amidst the beauty of nature encompassed by a high mountain and farming land'.

Andy Daniels recounts from last year:

'The hot spings where a bunch of wells with artesian (flowing water) hot water coming out. Mineral deposits had formed around the wells, there were maybe 4 total and some places where the water was just coming out of the ground. The water was too hot to soak and there were not many good pools. The only good pool was in direct sunlight and it was the middle of the day so I didn't soak. There was a park area around one of the well things that had grass and some food venders. It looked like they were working to build the hot spings up more, there was also a large sized pool that was not filled with water, and some privat rooms with little tile tubs that did not look maintained'.

Bangyai was more lucky and witnessed real soakers in the now empty pond:

'As hot springs go, nothing special but there were a few people there splashing around and boiling their eggs. I didn't fancy boiling my eggs so we hit the road again heading north for Mae Sariang'.

And elsewhere near Mae Sot
Mae Sot is very much the main town in this area. Previously this Soaking in Siam has highlighted hot springs in Umphang (due south of Mae Sot), however there is also a hot spring in Phop Phra district to the south of Mae Sot.

A couple of maps indicate there being another less well-known hot spring, Huai Numnak hot spring, also known as Pha Charoen hot spring which refers to the national park in which it is located (link to website with mention of hot spring).

Andy Daniels has also visited this hot spring which can be accessed by taking highway 1206 from the district headquarters itself. He describes his trip as follows:

'It was out in the middle of no where with no signed but I was able to find it after I passed it once and came back. It was large holes with really hot water, and completely natural. There was a woman in the house nearby that couldn't speak any english but was very nice, and was grinding rice separating the grain from the plant casing. I tried to soak my feet in some smaller concrete tubs near the source but they were too hot, I think the locals use them too cook eggs, that seems to be the main thing locals use the hot water for. Also the lady in the house had hot springs water piped to her house. She could tell I wanted to soak somewhere since I came all the way out there so she showed me where they clean dishes and I took one of the tubs they used to wash dished and soaked my feet, even then I had to let the water cool off for a while'.

So that's why I didn't bother heading there ...

Getting there: From Mae Sot take highway 105 north until just beyond km 13. Take the road to the east and continue until the road sort of ends in Mae Kasa village. Try following the most used road and you'll emerge on the other side of the village nearer the mountains. The hot spring is only a km away, below a dam.

Soaking Experience: Zilch!

Overall impression: Underwhelming.

Your Chiang Mai vid's

The website openchiangmai.com has been busy posting youtube vids concerning hot springs in and around of Chiang Mai during the last 12 months.
I thought that reposting the links would add another dimension to this site, unfortunately I am located in a real crap part of Asia where internet connections are soooo slooooow ...

It also highlights the tallest fountain as well. This will increase to every 30 minutes because it will look like under the tank when the water together until it is full tank. Up another time. This will heat about 150 í c ever to be increased by about 30-50 meters high at all, but now he has to put Valve then. That if we go to closing on weekdays. Because very few tourists. Because he used pressure to heat the generator, we should go on holiday will be more convenient.

'San Kamphaeng [Sankamphaeng] Hot Spring is located just 23 km from San Kamphaeng district and about 36 km from Chiang Mai City. It is situated amid natural surroundings of shady trees and fertile hills. The drive to the small weaving village of San Kamphaeng passes by a large number of handicraft shops and the famous umbrella village of Bo Sang. Some 3km beyond the village is the pleasant forty-acre park containing the hot springs.
The park has been well landscaped and in the cool season the flowers are very lovely making it a good place for picnics. There you can find a camping area, a swimming pool, restaurant dining facilities and segregated mineral water bathing room huts are also available.
The San Kamphaeng Hot Spring is the ideal destination for health and physical well being. The water has high sulphur content and possesses curative and restorative properties. This is a very active geological area. The water, at a temperature of a hundred degrees centigrade, comes from a deep source. Attempts have been made to harness this energy and there is a research station nearby with information on display'.

Raft

The spring itself gushing from the rock.

And I name you ....
How does one call a hot spring for which there is no name? The hot spring located along the Mae Klong river, Umphang district (Um Pang / Um Phang?), Tak is referred to by Thai as simply hot spring ('Pong Nam Ron') as do the local Karen (though 'Thi Ko' has a different sound). So should we name this Umphang hot spring? Or Mae Klong? Or use the Thai or Karen version?

To avoid confusion let's settle on the Mae Klong hot spring.

Twisted
Already mentioned is the fact that this hot spring is to be found in the district of Umphang, Tak province.

Umphang is probably one of the most remotest districts in the whole of Thailand. Located to the north of Bangkok, it's only road connection to the rest of the Thai nation actually runs northwards for 150+ kms before one can moves closer to Bangkok. This road (connecting to the town of Mae Sot) contains no less than 1200 curves and corners (Wikipedia) and is up there with some of Asia's most rollercoaster rides (see also Lao, road to Luang Prabang). Something to be proud of one can even buy t-shirts with the correct number of curves.

Largely populated by Karen (who have their own language), Thai language seems a minority language even giving Burmese more precedent.

Besides the twisting road, Umphang gains it's claim to fame by having Thailand's biggest waterfall, Thi Lo Su (Wikipedia, see also World of Waterfalls blog entry). Unfortunately world's leading travel guide book (Lonely Planet) knows exactly where the peanuts are best at which bar but does not seem to comprehend that it's more fitting info to tell readers that the access road to this Thai-class waterfall is impossible during the rainy season i.e. until November-ish.

Voting
It thus requires a raft plus a walk-in meaning a night should be spent at the foot of these falls.

Deliberation on the family front shows a slight majority in favour with a teenage son using his veto powers. Seeing his father nearly bleed to death the day before (or so it seemed) brought on by an attack of blood thirsty leeches while visiting another waterfall along the Mae Sot - Tak highway, there was no way he was spending a night somewhere outside of civilization (as characterized by the existence of wifi). Might seem like a waste.

So the alternative is a full day rafting. Which actually meant just 5 hours. But not really rafting, a float. Along the way we would be going through no less than 2 (!) rapids, pass under a waterfall, enjoy the silence of one of Southeast Asia's biggest undisturbed forests (the so-called Western Forest Complex of which Umphang Wildlife Refuge is just a small part of) and naturally the highlight of the tour a pass (and stop) at a hot spring.

Rafting down the Mae Klong river through virgin forest.

Getting somewhere
But not so naturally of course.

Setting off from the village of Umphang early morning, first up is the waterfall of Thi Lo Jau or Sai Rung (Sai Fon?). The raft floats under this waterfall and if there's any sun (from November onwards?) then a rainbow can be seen. Such it's name(s) which translate from Thai and Karen into rainbow falls.

Next up is the hot spring. Located next to a forest ranger camp (or is it the other way around?) there has been some effort been put in to make these appealing to the mostly Thai tourists. The spring itself is only located about 20m from the main river. Straight after the spring the side walls have been shored up with bamboo to prevent the sandy soil from caving in, the stream bed being 3m lower than the banks.
Roughly 5m down a number of sand bags have been placed to create a 30-50cm deep pool. Directly above the sandbags is a bridge with a bamboo ladder affording access to the soaking area.

Get in!

Toilets are available at the ranger station, 10m away. Rafts dock at the merging of the spring flow with the river. As one of the most natural springs I've yet encountered in Thailand, kudo's must be awarded to the lack of development and the natural undisturbedness of this hot spring.

That said, in season (from November onwards), hundreds of tourists file through here every morning en-route to possible better things downstream. One would hate to be here on such a day and I have seen photo's on the net with quite a few sardines packed into the hot pond complete with life jackets and all, let alone just your usual all day stinky clothes. Here one blogger recounts 25 soakers. This photo has just 19 soakers

The flow though is considerable and the temperature delightful (about 40C?), one could only wish to stay longer. Another great treat is to swim at the confluence. The streams of hot and cold alternate making this a great and exotic way of enjoying the water.

Alas sometime one does need to move on.

Andy
Prominently among bloggers on this hot spring I regard the postings by Andy Daniels who whilst touring Thailand turned into a soakophile. On Mae Klong hot spring:

'Then the hot springs were wonderful. Completely natural with maybe 102 degree water and under bamboo shade. I soaked ate some breakfast and soaked some more. Another hot springer showed up with his thai girlfriend, they also set up a special trip to spend hours at the springs. I was happy not to be the only crazy farang but still got all the attenting because the locals would say this crazy farang has been hears since just past 8 am and hardly anyone could believe it. My guides actually wanted to leave at 11:30 because the message about how long I was going to be there did not get to everyone so I guess the driver had been waiting for me since 9 or 10. I ddin't want to leave and jumped in the springs quickly and when I got out my guides said I could stay and go back with the other springer I had met. He had actually set it up because he could speak thai, and the guides talked to each other and agreed that I could go with the other guys. So my guides left me at the springs. I soaked for another 1.5 hours or so and then we all left together after eating some lunch ...'.

Other blog reports feature the fact that during season snacks are available here.

An impromptu mud bath.

Le So
Otherwise the official map of Tak province (see below) indicates another Umphang area located hot spring by the name of Le So Pong Nam Ron waterfall which is located near Le So village on the Mae Lumung river (lower right hand corner of map).
On internet I've yet to find anything while using the terms above. However the Umphang Phudoi.com has a map included on their website which refers to Liso hot spring. More info though also seems non-existent.



Getting there: From Umphang only rafts make it here so it seems.

Soaking experience: No other visitors meant having the place to one's own. A very relaxing and natural soak.

Overall impression: One of the better and natural soaks Thailand possesses, if only there were more!
