Indonesia’s best-known national park comprises several islands and some of the country's richest waters within its 1817 sq km. Expect hulking mountainous islands blanketed in savannah, laced with trails and patrolled by the world’s largest lizard – the Komodo dragon. That’s the big draw here, and it’s easy to spot them, but there’s also big nature beneath the water's surface where polychromatic bait draw big pelagics such as sharks and manta rays in great numbers. Nearby Labuan Bajo, on the island of Flores, is the perfect traveller base.
