Absolutely not to be missed is a trip to this home of the national bird of Trinidad and Tobago, the legendary scarlet ibis, whose return at sunset to roost has been called the most spectacular exhibition in the avian world. Hundreds of the bright red birds, with wing spans of more than 3 ft/1 m, fill the sky and cover the trees like Christmas ornaments. Egrets, herons, and a host of other birds and animals share the swamp with their flamboyant friends. The only way to reach Caroni is via the tour boat that leaves daily at 4 pm from Bamboo Grove Settlement No. 1. Call ahead to reserve tour space, and do not go unless you carry mosquito repellent—you will not enjoy this trip unless you have protection. (US$10 adults. Phone Nathan's Bird Sanctuary Tours at 868-645-1305.) 4 mi/6 km southeast of Port of Spain.
