It took a few more minutes of uphill hiking before we finally encountered the third Erawan Waterfall, which was called Pha Num tok (or Pha Nom Tok) and 220m from the visitor center. And like the first waterfall, this one also had lots of fish swimming in its plunge pool because most of the people chilled out at the second waterfall. However, this one was significantly taller than the first two (possibly 20-25m I think) though not nearly as wide.
Adding to the scenic allure of this waterfall was the colorful blue-green water of the plunge pool keeping us from getting all the way to the falls without swimming. It was up there with the 2nd waterfall as one of our favorites in the lot.
Further up the hike, the fourth Erawan Waterfall was more of a water slide. It also had a larger drop further downstream, but it was hard to see. We saw one person scoot himself on the rounded rock of the waterslide before finally letting gravity take over. This falls was called Oke Nank Phee Seah, and it was about 520m from the visitor center.
