Haven't been to Rockland's in a few years, but the last was a circle route as Captaind describes except we turned on the B8 at Ferris Cross which is on the satellite view above. My only regret was that we had an appointment at Rockland's for a tour of the grounds so I couldn't stop to explore on the B8. There were several bars, restaurants, views, etc. that I was wishing I could check out. I recommend making the trip in the other direction. Go to Rockland's in the morning and allow plenty of time to dawdle along B8 on the way back to Negril.
Rockland's is one of the most magical places in the world. Take the guided tour, too. Cool runnin's --Marblehead
