For the extra-intrepid, a wealth of guided glacier walks and climbing experiences are available, tailored to suit all ages and abilities. If you have cash to splash, the mother of all glacier encounters is a heli-hike, complete with snow landing at the top of these slithering tongues of ice.
When you've had your fill, hop across to New Zealand's most spectacular natural mirror. The dark, inky waters of bush-ringed Lake Matheson deliver reflections of the soaring Southern Alps, with Mt Cook and Mt Tasman stealing the show. Try to time your visit for sunrise or sunset, when the light is softer, and nature's paintbrush is accentuated.
In Franz Josef township, the West Coast Wildlife Centre is where you can admire the world's rarest kiwi, the Rowi. The wildlife centre is home to the official breeding programme for this highly endangered national treasure, which is indigenous to the region.
The centre is particularly popular with very young children, and it also features interactive glacier displays and wildlife films.
Franz Josef is threaded with enchanting walking tracks. My favourite is Callery Gorge track, which crosses pristine rainforest to Callery Gorge Bridge, and takesan hour to complete.
Top off your day with a soothing soak in the Glacier Hot Pools, snugly secluded in native bush.
