Your best bet in Jamaica is to book some kind of an excursion. Always best to be with a group. Jamaica is actually a very beautiful island, very lush with many good things to do. The falls is always an exciting excursion if you haven't already done that, worth the time....just beware of the vendors at the top of the falls, they don't like to hear you say "no". I must agree, they have some of the most agressive people I've come across on the islands.
