Walk around in this lush tropical forest and keep an eye out for monkeys and birds in the trees overhead. A natural wonder of Barbados, this gully used to be a cave until the roof collapsed, so you can still view stalactites and stalagmites as you walk. Only a mile long, it’s a fairly easy walk, and if you’re lucky you can catch the monkey feeding, which usually happens sometime between 10 a.m. and noon.
