I also visited here while on a cruise – working on a cruise ship actually! We wanted to visit a waterfall and were told there were two options: the bigger one on horseback and a smaller one by taxi then foot. We didn’t have time for the big one so we did a short couple hour trip with some locals to the small falls. Some local children led us by the hands down to the falls, where we played with them in the water. It was a nice little afternoon. Yes, lots of poverty. Of course we have to pay for the excursion ($15 I think?) and tip the children who lead us around.
