Isn’t nature the greatest tonic? It certainly is on this South Island tour encapsulating the region’s hits, as well as some unsung gems. At sea level, cruise Milford Sound or chug across the isle on the TranzAlpine; from altitude, alight on Franz Josef Glacier in a chopper or explore Mount Cook. Your city gateways – Queenstown, Christchurch, Dunedin – envelop arguably the world’s best wineries.
