Do NOT do the Dunns River Falls tour. The falls are gorgeous, but you are herded up them like a bunch of cattle. I had a tour guide for the next group right behind me, and he kept blowing his whistle and yelling in my ear. I had a terrific headache afterwards. Also, you spend 2.5 hours on a tour bus each way. You do get to see a lot of Jamaica (mostly desperate poverty), though. And the drivers in Jamaica are absolutely crazy!! I was glad I was sitting in the back of the bus so that I couldn't see how many close calls we had.
