About Dunedin

Dunedin's octagon and the University of Otago's Victorian buildings give the city its Scottish feel, with the railway station's mosaic floor a favourite stop. The Otago peninsula shelters albatrosses, penguins and seals at Taiaroa head, and the Taieri gorge railway runs inland. November to March is the warm season for wildlife; winter is cold and quiet, and the peninsula's colonies are busy in spring.
