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.
