Hiring a personal driver will allow you to manage your own time at the park. Just make sure you leave early, so you can have maximum time exploring the falls. I don't know how much a personal driver will charge. I would research the cost against doing a tour and then negotiate the price accordingly. If you decide on a group tour, be sure to find out how much time they allow you to have at the park. Also, research different tour companies to find the best one. Look at online reviews amd ask at your hotel. Have fun!

Hi, I was wondering the same, how did you manage in the end? Thanks in advance!

it is about 200 kms from Bangkok I advise you to stay in Kanjanaburi for 2 night it has a lot to see

can you clarify what do you mean by Nam Tok? Nam Tok is the Thai word for waterfall. do you mean from kanchanaburi to erawan?

Yes. There is a guard at a shelter at the 2nd or 3rd waterfall where you are supposed to leave all of your bags. I have heard that you are not supposed to take food etc farther up the trail to see the rest of the waterfalls.

Dogs are not allowed. There is a big sign at the entrance. We didn't know, went there with our dog and they didn't let us in.

Bonjour, Effectivement il s'agit de chutes d'eau avec cascades dans la forêt et possibilité de s'y baigner. Les hôtels sont du côté de kanchanaburi (avec le pont de la rivière Kwai). Sinon vous avez une centre hotelier entre la ville de Kanchanaburi et le parc Erewan : le River Kwai Park & Resort (il se trouve sur la route qui emmène de Kanchanaburi au park)

I think you can do it. You can take up a stick to support yourself if you do not feel confident. Except for the road to 5th to the top most tier, the rest of the places aren't that steep. Good luck!
