I birded there around July 2007, basically around a nature park there, but forgot the name. Not very impressive. The trail was not well maintained.

Try typing some key words like south thai birdwatch and do some research, e.g. this website

You may have a chance to visit Khao Sok NP if you have time.

Purple swamphen. Quite easy to see this bird at the golf course.

The national park should be Khao Phra Thaeo National Park.

Good luck
