Phatat cave. Erawan National Park.
Not sure what the old entrance fees were. Caveat here. If you pay for entry to Erawan Falls/National park you don’t pay again for this location.
Unfortunately we went to Huay Mae Khamin further up which is beautiful but not the same national park.
Also mentioned that I live and work and showed work permit. Still a firm no.
I was not willing to pay the 300thb again.
