We head towards the east coast via the massive Clyde Hydro Dam and the Central Otago fruit growing basin. Dunedin is famous for its student activity, being home to 20,000 plus students at Otago University, the city is also well known for its Scottish heritage. On arrival we do a city tour including a visit to Baldwin Street, the world's steepest street and in the evening there is an option to visit another icon of Dunedin, the Speights Brewery with one of their tours and tastings!
The Catlins is probably as far south as you may ever go. Travel through awesome native forest, sandy beaches and see rare wildlife. The might of the New Zealand sea-lion (New Zealand's largest native mammal) is a real highlight as are the many short walks to the Catlins natural attractions, which includes a 180 million year-old fossilised forest (where you are also likely to see Yellow-eyed penguins returning from a hard days fishing). The night is spent in Invercargill, home of the world's fastest Indian and Henry the tuatara! Here you have the choice to hop over to Stewart Island - it's definitely worth the visit, an island paradise with a kiwi (bird) population 100 times that of the kiwi (human) one.
Travel through to Milford Sound checking out the most amazing scenery in New Zealand along the way. The day includes a two hour boat cruise through the sound exploring soaring peaks, towering waterfalls and New Zealand nature at its best. See the Homer Tunnel, gigantic waterfalls and amazing fiords. See the Homer Tunnel, gigantic waterfalls and amazing fiords. If you have the time jump off in Te Anau, the gateway to Fiordland National Park and home to a stunning lake, and/or in Milford Sound to spend a night or two. Provided the weather and bank balance permits you have the option of flying back to Queenstown, otherwise the Kiwi Experience bus will take you back to the adventure capital.
