Macapá is on the north channel of the Amazon Delta and, like Belém, was built by the Portuguese as an outpost. Today it's the capital of and the largest city in the Amapá State, with 150,000 people. It's also one of only five metropolises in the world that sit on the equator. Macapá's main lure is as a base for trips to see an extraordinary phenomenon—the pororoca (riptide).
