Tobago's lush hills are home to more than 200 species of birds. The Tobago Main Ridge Forest Reserve, a UNESCO World Heritage Site, offers great hiking and bird-watching on the Gilpin Trace, as well as a wonderful place to cool off—the spectacular Argyle Falls. But a shorter and easier excursion can be found closer to Scarborough at the Grafton Caledonia Bird Sanctuary. As you stroll around this former cocoa farm, keep your eyes peeled for motmots, tanagers, mockingbirds, hummingbirds and chachalacas. A nearby eco-resort, the Cuffie River Nature Retreat, runs guided bird-watching hikes.
