I didn't read all the replies but I always wonder why nobody ever suggests the lighthouse. Around 3PM take a taxi (Call Linston it really makes sense to do this) to the Lighthouse. Wander the grounds. If you're lucky you will run into the groundskeeper and he will let you climb to the top of the lighthouse. Really a spectacular view. From there... walk back to Rick's for Sunset (1 drink MAX). Along the way you will see LTU Pub, it looks small but is really a great place with great food. Don't eat at Rick's!!! If you want to start earlier, just keep walking down the cliffs looking for places to have a drink. Past Ricks will be Catch A Falling Star (Ivan's Bar), Tensing Pen, The Rockhouse, The Push Cart and 3 Dives all great places for dinner and sunset. When you're done call Linston for your ride home. You'll see plenty of the "Real" Jamaica off the resort this way.

If you do start earlier have Linston take you up to Out of Town Pastry for Patties prior to dropping you off at the Lighthouse.
