Besides Pong Krathing hot spring, Ratchaburi province has another hot springs site: Bo Klueng hot 'stream'. These springs are situated in the Suan Phueng area, a recently approved accessible area of Ratchaburi province quite near the Burmese border. It used to be off-limits to all but locals due to the Thai-Burmese border relations or lack of relations more probabbly.
The area is now seeing quite a lot of tourism related construction: due to the amount of natural attractions, it’s ease of access to Bangkok (two hours if you fail to take your foot off the accelerator), it’s slightly cooler climate (due to it’s higher elevation) and enchanting natural surroundings (or did I mention it already?). Recently finished are a number of resorts / restaurants with others set to open in the near future. Roadside stalls specialize in selling plants (esp. orchids) and ‘souvenirs from Myanmar’ the politically correct name for the politically incorrect country of Burma.
