I went with a friend, we are both girls. The falls are great but we dindt enjoy so much the trip because the guides. The entrance woman was really nice but later, at the falls, all the guides were speaking and joking about us. Our guide even told the rest of the guides that we were changeing. They were looking us too close and asking if I dindt want to take off my tshirt. We were the only ones that didnt have a helmet on the falls. later we took the kayak to go out from the place and they stopped us in the exit. when we went out of the kayak they were around 10 men laughing and joking about us. they were asking us to change our clothes. We told them that we wanted to go to the exit (we didnt feel comfortable of changeing there with all them around looking us) At the end one of them pointed the stairs when we asked again for the exit and we walked fast up stairs. the guide came some time later (was one of those men). In addition all the guides were asking us for a tip all the time the place is great but definitely not nice for going alone if you are a girl, it was creepy and scary.
