Half Moon Beach is just past Rhodes Hall--about 15 minutes or so from Negril. No entrance fee, but please buy drinks/food while there. I just went a few weeks ago and had a really nice afternoon there--snapper sandwich and cold red stripe to fortify me. Loungers w/cushions are on the beach. When I went there was no one else on the beach but a few people eating lunch there. It is a really sweet spot.
