we been a few times to mayfield falls in all of our trips and love it!
definetly hire a driver and go to the falls. cost is 15us to get in and tips for the tour guides that will take pictures operate camcorder for you etc....
have your drive stop in sav lamar for some good food then on the way back stop at the lighthouse on the end of the cliffs in negril. Tip the keeper a few bucks he takes you to the top and gives you all the history of the lighthouse really cool and the views are priceless
