We stayed at Zion Country for 12 days and really loved our stay. The cabins are basic but good, the garden is beautiful (and full of humming birds) and so is the view overlooking the bay. The optional evening meals are really good. The evenings were spent chatting with Free-I, Owen and the other guests, enjoying a red stripe or rum-and-coke. All-in-all a very relaxing place to stay.
Besides that, Portland is astonishingly beautiful, both the beaches and the mountains, and the fact that there's no mass tourism there, gives you the chance to experience the real Jamaica. We will definitely be returning to Jamaica in the near future and will spend at least a few days at Zion Country.
