the waterfall itself is beautiful but it's crowded with locals. didn't get a chance to swim there though. Overall the area doesn't offer much. You can expect many locals having their "picnic" day out there. I was there for 30 minutes and I got bored already. Do prepare insect repellent as I got bit by a fair share of mosquitoes. To gain easy access here, take the weekend train from Bangkok Hua Lamphong station which departs at 0630, train 0910. It will take you straight to Nam Tok Sai Yok Noi station which is the terminus for the death railway. costs only 120 baht with advance reservation required.
