If you still have some time left, you can go to the Rocklands bird feeding station. This farm is in Anchovy, half an hour from Montego Bay. There you can live a unique experience, feeding the little hummingbirds with your own hands.
20 minutes from Montego there is the Rose Hall Great House. Although Annie Palmer died more than 100 years ago, she is still known as the white witch of Jamaica. She murdered three husbands and was killed by her slave lover.
