Why Barbados has caves and gullies

Why go

The island's landforms show what water can do above and below ground. Rain moves through limestone, carving underground passages such as Harrison's Cave and helping shape gullies including Welchman Hall Gully. Uplift and erosion also produced the island's terraces and the more broken terrain around the Scotland District. On the east coast, waves continue to work on the exposed shore. Seeing a cave and a surface landform on the same trip makes the geology more than a map label.

What to look for

• Harrison's Cave shows water-cut passages inside limestone.
• Welchman Hall Gully reveals a different limestone landform at the surface.
• The Scotland District has a more rugged profile than the gentler western slopes.
