Off the coast of Port Antonio is a small, uninhabited plot called "Pellew Island," otherwise known as "Monkey Island"--there used to be a colony of imported monkeys here. To get here, you could first head to San San Beach, a beautiful and private stretch open daily (10 a.m.4 p.m daily, US$5). Rent a kayak and snorkel gear and make your way over to the small plot, within clear view ahead. The island is completely covered in vegetation, there's a small white sand beach, and the waters are shallow. Rest your kayak on shore and snorkel around the island for as long as you please. Visibility is incredible and this is one of the best snorkeling spots in the area. Just watch your step if you're barefoot, as there can be sea urchins on the seabed.
