ABSOLUTELY be careful here. Once you climb the falls, they try to drag you through the locals crafts area. They tried to take my husband one way and me the other. We had just climbed the falls and had no money. It was very scary.
And the guys who take your pictures throughout the falls are NASTY at the end when you don't buy their pictures or videos. They also get NASTY if you don't give them tips.
BEWARE - BEWARE - BEWARE
