One of the world's great rail journeys, the TranzAlpine travels between Greymouth and Christchurch daily. The journey is 223.8km long, takes four and a half hours and includes 19 tunnels and four viaducts, the highest being the Staircase reaching 73m. It's all aboard for departure from Christchurch at 8.15am and again from Greymouth at 1.45pm. The journey makes a great weekend getaway or longer trip. All you need to do is sit back, relax and feast your eyes on the sublime views of the Canterbury Plains, Waimakariri River's gorges and river valleys, and the Southern Alps.
