Walking down the road to the waterfall is very slippery with moss so you have to be careful. There are 5 levels you can access. It's a beautiful place but very hard to walk/climb. There is a walking path for about 300m but after that you are climbing over rocks to get any further. I found it hard to walk and slipped over hurting my knee so only got to level 2. My husband walked further up to level 4 but found it very hard to access level 5. You can buy food to feed the fish which is really cool. Lots of beautiful butterflies.

We arranged the trip to the national Park by asking a taxi driver in Hua Hin nigh market about prices etc. He picked us from the hotel and waited at the Park Gates while we went sight seeing for about 2 hours. The travel took about 1 hour. Price of taxi was 1600 baht (41€) and Park fees from 2 adults 2 children 900 baht (23€). At the Gates they sold fish food for 10baht a bag. There are thousands of carp in river; feeding them was a fun activity. There is also a small kiosk that sells refreshments but no actual food besides cup noodles. The waterfall is 11 tiered but you can only climb the 5 first levels as rest are on Myanmar side of the border. It took us about 1,5 hours to climb. Bring enough water for it is warm and humid. Climbing is quite challenging at points and you will need to cross the rapid by stones at one point so good shoes are must. Our 6 year old had no trouble on the trail.

About an hour taxi ride from Hua Hin. Our kids are into entomology, especially butterflies and the sheer volume of butterflies on this hike was astounding! We hiked with 4 kids ages 7 to 14 to the fourth waterfall and then swam by the waterfall and fed the carp with 100 baht fish food available at waterfall entrance. If you have little kids ages 5 and under, getting to the first and possibly second falls is very doable. It is 800 meters to the 5th falls from entrance. On the way to the 3rd/4th falls, you climb over rocks/boulders and rope handholds are available. There are some very steep dropoffs from trail to water below so we pointed this out to the kids and kept our younger kids close to us. Some of us hiked in tennis shoes and some in flipflops/barefoot. We loved each of the 3 activities we did today (Treetop Adventure, Hutsadin Elephants, and Pala U), but this was 3 of our kids' favorite. We spent about 1 hour 30 minutes hiking/swimming. Also, we ate lunch at the Pala U Cafe before the park entrance and it was idyllic, hammocks, tree swing, amazing views. We could have easily spent a couple hours at the Cafe relaxing.
