Entry is 100 thb for foreigners plus 30 thb for a car. This waterfall is a series of 10 levels, some more dramatic than others. There are three parking areas. If you park at the top level, you can access level 3 to level 10. Some people have said that solid shoes are required, but I did not find that to be the case. The entire path is paved with concrete or stone, and there are no real steep stretches. Flip flops will work if you are used to walking in them. Crocs, probably not. If time is limited, rather than push all the way up to level 10, I would concentrate on levels 5, 6, and 7, the most dramatic falls. There is a checkpoint at level 6, with an attendant. Appears that the upper levels are sometimes closed. Toilets are available at each parking lot. Toilets at lots 2 and 3 are not too fancy. I didn't try the toilet at lot 1, but the building looked new, probably the place to stop if you need sit down. There are food sellers at lot 3. I ordered pork liver salad for 100 thb. Food was tasty and the ladies were eager to chat.
