The Boiling Hole is a small, odd piece of South Caicos history: a natural underwater passage where seawater pushes into the island's salina. At high tide the water can look as if it is bubbling up from below, which gave the place its name and made it useful to the island's salt producers.
Come for context rather than spectacle. The hole sits beside the old salt ponds, so it makes most sense as part of a walk or drive through Cockburn Harbour's salt-industry remains. The landscape is flat, bright, and exposed; bring water, sun protection, and a little imagination for the days when this quiet island exported salt across the Atlantic.
