Really sorry just picked this up so think it's too late . I wore shorts just above knee and I don't recall covering up .

ppen mpst days ask your hotel cocierge

Beste je kan prima de kinderen meenemen naar de killing fields wij hebben onze kinderen van 11 en 13 meegenomen en zij hebben de hele rondleiding meegelopen met de koptelefoons. Heel indrukwekkend

In accordance with the first answer I agree that there is no good place for your kids to play. Of course they can sit and wait at the entrance and read a book or something like that. If your children are next year 12 and 9 years old, I strongly recommend to take them with you. The visit will take approximately 45 minutes - one hour. Years ago you could see awful sights (like little pieces of bone in the ground), but nowadays that has gone. Our children (the youngest being 14 years) liked the audio-guide (also in Dutch), although quite impressive. Maybe it is an idea to watch the movie “first they killed my father” together with your oldest child? Have a wonderful time in Cambodia!

Tuk Tuk is about $15, otherwise go with a car hire company, public transport is unknown

Yes it is there. You can find these on the internet, where there are also maps of the place as well as prices

I’d ask your hotel concierges service to contact them to confirm. It just may be open.

You can look on several sites of this fields looking for opening times. I didn't liked it much. Not much to be seen. How terrible and horrible it was. This may never happen again. But there is not much to see. Better have a look in Prison 21.

I think it was around $10 (Australian ) and Audio included

Der 1.1 ist dort auch ein Feiertag. Aber falls ihr schon ein Hotel gebucht habt würde ich mal ne Mail schreiben, ob dann auch die Sehenswürdigkeiten geschlossen haben. Falls ihr sonst noch fragen habt oder Tipps braucht könnt ihr mir gerne eine private Nachricht schreiben.
