Just seven hectares (17 acres) in size, the Botanical Gardens in Scarborough pack a tropical punch. They were founded in the 19th century on a former sugar plantation, with views of the town and bay. Visitors will see orchids and bromeliads, royal poinciana and silk-cotton trees, a huge saman tree with spreading branches and an allée of stately palms. Keep an eye out for the island’s colorful blue-crowned motmot bird flitting about the grounds.
