Marlborough Sounds - Blenheim 5.23

The Marlborough Sounds are an extensive network of sea-drowned valleys at the north end of the South Island of New Zealand. The Marlborough Sounds were created by a combination of land subsidence and rising sea levels at the north of the South Island of New Zealand. According to Māori mythology, the sounds are the prows of the sunken wakas of Aoraki.OverviewCovering some 4000km2 of sounds, islands, and peninsulas, the Marlborough Sounds lie at the South Island's north-easternmost point, between Tasman Bay in the west and Cloudy Bay in the south-east. The almost fractal coastline has 1/5 of the length of New Zealand's coasts.The steep, wooded hills and small quiet bays of the sounds are sparsely populated, as access is difficult. Many of the small settlements and isolated houses are only accessible by boat. The main large port is Picton on the mainland, at the head of Queen Charlotte Sound. It is at the northern terminus of the South Island's main railway and state highway networks. The main small-boat port, Waikawa, is one of New Zealand's largest and provides a base for leisure sailors and vacationers.
