By all means you should venture out from your resort and see more of what Negril and Jamaica have to offer. If it is your first time visiting, you should hire a guide to show you around so you'll see more than your tour guide book can ever tell you!
Music lovers, especially those who dig reggae, should not miss live shows at Alfreds and even at Red Ground. Usually there is some sort of live show every week, accompanied by massive sound systems and dancing under the stars! Taxis are readily available to take you to and from these events.
