Auckland is one of the few cities in the world to have harbors on two separate bodies of water. The central part of urban Auckland covers a narrow isthmus between the Manukau Harbor on the Tasman Sea, and the Waitemata Harbor on the Pacific Ocean. In addition, Auckland's diverse geography and warm, humid climate has inspired a lifestyle regularly ranked in the world's top ten. A half hour drive from the city there is an abundance of activities: sailing to a secluded island, trekking through the rainforest, picnicking on a volcano, sampling wines at a vineyard or exploring a black sand beach.
