Caroni Bird Sanctuary (Trinidad).

This sprawling mangrove wetland on Trinidad’s west coast is the premier roosting site for the scarlet ibis, the island’s brilliant, flame-colored national bird. Just a short drive from Port of Spain, the protected estuary of channels, lagoons, and mudflats is best experienced on a late-afternoon boat tour. As dusk approaches, visitors glide through the quiet, brackish waterways to watch spectacular waves of scarlet ibis and white egrets return to settle on isolated mangrove islands. Beyond the famous avian display, the swamp is a thriving ecosystem where sharp-eyed guides spot roosting silky anteaters, caimans, and tree-climbing crabs. It is a genuine, rustic wilderness—meaning insect repellent is a must—offering one of the Caribbean’s most arresting natural spectacles.
