I live around 30 kms from Chulabhorn Dam so thought that i'd post a few pics and information for all those who may wish to visit in the future.
Chulabhorn Dam is owned by the Electricity Generating Authority of Thailand (EGAT) and is situated around 125 kms west of Khon Kaen. Travel west through Chumphae and then on another 25kms to Khon San where you will then need to turn left (heading south) at the crossroads. This road then leads to the dam (another 35 kms) which is situated in the mountains. Very little traffic on this well maintained road which makes it a very pleasant drive.
Can someone sort out the photo's for me?, i'm a complete novice as is clearly noticeable.
From top left/right: after negotiating security personnel at the entrance (i have never asked for ID, just let them know you're a visitor) drive straight on and past the Blue Dam sign, down a steep hill and back up again where you will eventually reach a junction. The restaurant can be seen when you turn right as can the dam.
I will add more if the photos can be enlarged
