Cabo Rojo, located on the southwestern coast of Puerto Rico, is a region of striking natural contrasts where salt flats, mangroves, and limestone cliffs meet the sparkling Caribbean Sea.

Lake Toba is another of the island's spectacular sights - a remarkable volcanic crater set in the middle of northern Sumatra, 176km from Medan. The lake is huge (the largest in South-East Asia), occupying the caldera of a giant volcano that collapsed on itself after a massive eruption some 100,000 years ago.
