Barbados's natural beauty isn't confined to its beaches. Though most of the forests were chopped down centuries ago to make space for sugar-cane plantations, there's still plenty to explore, especially in the Scotland district – the ambitious name given to the central highlands by early planters.
For a glimpse of pre-plantation Barbados, visit Welchman Hall Gully (001 246 438 6671; welchmanhallgullybarbados.com; US$12/£7.50), pictured, a tangle of exotic plants and trees that includes the only two endemic plants to have survived the planters' axes: the gully shrub Phyllanthus andersonii and the climber Metastelma barbadense. You might catch sight of a green monkey too – they're generally hounded as a pest on this island but welcomed here. To make a day of it, tack on a trip to nearby Hunte's Garden (001 246 433 3333; huntesgardensbarbados.com; B$30/£9) and the Flower Forest (001 246 433 8152; flowerforestbarbados.com; B$20/£6).
For natural history with thrills and spills, whizz along the zipwire at nearby Jack-in-the-Box Gully with Aerial Trek Zipline Adventures (001 246 433 8966; aerialtrek.com; B$92/£29), a 1,000ft-long ride through the treetop canopy that reaches heights of 100ft above the valley floor.
