We did the Dunn's River Falls climb in December. There were several young children with us. It all depends on the children. It's a pretty strenuous climb, can be slippery and takes quite some time. So it could be difficult or frightening for young children but it all depends on how they are. At those ages, I would have probably been too scared (I was really short for my age and not very athletic and didn't like doing anything that might impact my glasses or impair my vision) but my sister would have been fine as she was quite athletic and didn't wear glasses. Now, however, I can't see her doing it but I had a blast.
