Stone and concrete steps—1,064 of them—rise to a mahogany grove at the summit. En route, the steps pass giant elephant ears, ferns, begonias, mangoes, palms, and orchids—six identifiable ecosystems in all. Staff at the Trail Shop in Windwardside can provide a field guide. Have your hotel pack a lunch, wear sturdy shoes, and take a jacket and water. The three-hour round-trip is best begun in the early morning.
