This 550 sq Km park is one of the most beautiful in Thailand.
2Km walk (a steadily walk!!) from the trail entrance to the end of seven levels of waterfalls. The trails weave in and out of several pools and falls.
The shape of the highest fall is said to resemble Erawan, the three-headed elephant of Hindu mythology.
During your trekking, you can also see monkeys jumping from the the trees, fishes,... and make a nice swimming in the falls.
