Just a couple of pieces to share as well as one news piece and a link to a lesser known Siamese soaking site ...:
'another smaller pool, this is the least warm pool, the baby is really enjoyed it'.

Unfortunately no picture on this allowed, but nonetheless it's a small but interesting write up on flickr, concerning Kapong hot spring, Phang Nga Sam Spicer notes:
'This is a hidden gem and doesn't feature in a single tour itinerary! I wouldn't have known about this lovely natural hot spring if it wasn't for a Japanese friend who runs a delicious restaurant in Bang Niang, Khao Lak. (www.enzointernational.com/). If you want directions to this place, I'm sure Toshi-san will be able to provide them for you!The hot springs are fantastic, and if you go around sunset, a lot of the locals will be there taking their evening dip! Take a few eggs to heat up in the hot spring sources and then enjoy your boiled eggs with an ice cold beer. It doesn't get much better than that!This place is just one of the many reasons I love Phang Nga province. There is simply so much nature to be enjoyed here, much of it away from the tour buses too. It's still possible to feel like you're really exploring a jungle or getting off the beaten track'.
A testament to a great experience. I've been there!

'K.D Asset and Development Co recently invested THB650 million (US$21.87 million) in new project Zen Next, which it has earmarked as the ‘first Onsen Condominium in Thailand’.
It notes that a hot spring will be developed. One must also note that there is no natural hot spring nearby.
