Clarity...tough question, but a darn good one!
I have to add a few to your list that we really enjoyed as well.
Lovers Leap-The most beautiful view and love story, about Tunky & Mizzy...and if you belive, you can feel their spirits.

Rocklands bird sanctuary-feed hummingbirds, they land on your finger and you feed them from a tiny bottle, an amazing experience, these birds are not captured they are in their natural environment, learn about the healing herbs and plants used as natural remedies throughout the country, a very affordable and special excursion, only minutes from Montego Bay and the scenery is delighful.

Luminious Lagoon-Glistening Waters-Not too many of these lagoons around the world and to be able to experience it in Jamaica-well worth it.. bioluminescent waters .. the water glows, i was glowing, the fish swimming by were glowing, it was truly amazing.
look up some pictures on google images!! amazing it was!

can't wait to hear your pick! have an amazing time! and can't wait for the next trip report! One Love!
