Niue is an island country associated with New Zealand, positioned between Tonga, Samoa and the Cook Islands. Unlike them, Niue is a single island which area is about 261 km² (100 sq mi), and a rather elevated one, with two levels: the lower, a coastal terrace, 25-27 m (80-90 ft) high, and the higher, a limestone plateau reaching 60 m (200 ft) above sea level. Coral reefs surround the whole island, with the only major break next to the capital, Alofi. Although Niue is just a small island with a population of approximately 1,500 people, it offers plenty of activities. Diving, snorkelling, fishing and other types of water recreation, traditional to most tropical islands, are accompanied by whale tours and 13 hiking trails, from easy to hard. Experience the one-of-a-kind landscapes and the blissful authenticity of Niue!
