I have been to Jamaica a handful of times and have brought some limited gear with me. I have climbed some cliffs that are located in Negril. This is a long drive from Montego Bay. If you go to a place called Rick's American Cafe, you will see some limestone cliffs that are fifteen feet from the bar. About 40-50 feet high touching down in a beautiful little bay. You won't be the first ascent there. Maybe the second? You can solo above the water to the point where everyone jumps off. Once there you will see the possibilities all around you. Be warned the rock is very, very sharp. Very sharp. Good luck.
