I went to Mayfield on my last trip; we left about 8:45 and were back a bit after noon. It was about an hour nice and easy trek up the waterfalls. Mayfield is the closest Falls of the big three to Negril. A friend that went with me also went to YS falls and later Dunn's river falls and said he liked YS the best. Not sure about where Blue Hole is in respect to the others.
