In a word, New Zealand's South Island is known for nature. There are also contemporary cities offering world class dining, shopping and cultural delights which are well worth a visit. South Island NZ is a haven for nature and adventure lovers.,There is no right answer when comparing New Zealand's North Island to the South Island. Really it depends. For those seeking warmer temperatures and more of a metropolitan vibe, North Island is better. For those seeking an escape amongst nature and wonder, South Island is better, however both natural beauty and metropolitan cities can be found on either island.,Some must-do experiences in South Island NZ include going for a hike on Mount Cook - New Zealand's highest mountain, visiting UNESCO world heritage site Fiordland National Park, staring up at the stars in Lake Tekapo - part of the UNESCO dark sky reserve, going skiing in Queenstown, and going on a street art trail in Christchurch.,You could drive from the top of South Island NZ to the bottom in around 14 hours however this is not recommended. Rather it's better to travel along the coast, visiting all the cities and landmarks along the way. For those planning a road trip around the South Island, at least a week is recommended although more time would be even better to allow you to see more cities and take longer stops. Plan for two weeks for a truly memorable experience.
