I must have visited Klong Plu water fall on at least 3 occasions now, saying that though we always tend to frequent the same places when we visit Koh Chang. Klong Plu is a nice morning or afternoon out, and as such it is the most visited waterfall on Koh Chang.
Because the waterfall is inside a national park there is an admission fee of 200 baht for adults, and about 100 baht for children, considerably less for Thais though. Klong Plu waterfall is open to visitors between 8AM and 5PM, from the parking area it’s about a 15 minute walk along a forested path which runs parallel to the river.
It’s not a spectacular waterfall, I don’t know how high it is to the top, I read one article claiming it was 100 meters, I would guess it’s closer to 30 or 40 meters. In any case, the plunge pool at the bottom of the waterfall seems to be the main attraction. In some places the water is deep enough to jump in from high off the rock face. The water is refreshingly cool rather than shockingly cold, but the first leap in might result in a sharp intake of breath.
The track to Klong Plu is quite rough, my kids manage it in flip flops but I suggest Crocs or at least something with a heel strap.
The many things to do on Koh Chang are what make it one of the most appealing of the islands near Pattaya.
Although, in reality, you would hardly call it near, getting to Koh Chang from Pattaya is straight forward and cheap, and well worth it.
