฿40 to park a car and ฿200 for non-Thai. Pleasant staff and the trail is in really good condition. The whole trail is shaded and only opens up at the waterfall itself. Not too busy but not empty around 13:00 and the fall is still worth seeing in the Dry Season. 40 minutes from car park to fall if you stop at viewpoints and take photos, 20 minutes if you don’t stop. Advisable to wear shoes as although the trail is fairly easy, there are parts that are momentarily steep or require proper footholds.

The waterfall is beautiful! Seen during the rainy season so really a lot of water... even on the access road (provide shoes accordingly) on the other hand forbidden to swim there. You can only swim below with carp fish in a pool with a little current. Pricey entrance (200 bht per person)

A shady and wooded path, rich in flora and fauna, along an amazing stream, clear and sweet, the waterfall is very impressive, high, in front of it is a beautiful pool. But! The entrance fee is 200 baht for an adult and 100 baht for a child and there is no access to the waterfall nor to the pool in front of it, there is a guard and a physical barrier in the place (a taut rope as a border). This is very disappointing! So disappointing that I doubt if the price and effort were worth it...

This is a nice, short walk to a pretty waterfall. We enjoyed it. The path is uneven with lots of rocks to use for clearing over mud and very shallow water, but not terribly difficult. Take your time. They do not allow swimming in the top pool near the big waterfall but you are welcome to wade and swim at points below the upper pool. The water was cool and refreshing. 20 Baht for Thais 200Baht for foreigners. Some complain that this is unfair but there are costs to maintaining national parks and attractions. A pleasant way to pass 30 minutes for a quick peek or an hour or 2 if you take some time for a swim.

Visited Klong Phlu Waterfall as one of the sites on a day trip around the island of Koh Chang (on this day the mini van was me and tourists from various European counties). Bit of a hike in the rainforest and its amazing screeching insect (track more or less follows the river) to reach the waterfall where people gathered with some enjoying a dip in the pool. Fish in the pool nibble at your feet. Visitors went back and forth along the track as a tourist site, but still worth doing. Perhaps better to visit independently rather that as part of a tourist group. That way give yourself more time to sit and appreciate the falls and forest; also other things to explore in the Mu Koh Chang National Park. Maybe take a picnic. A nice natural place on Koh Chang.
