Staying in Hokitika meant we were a short (but mountainous) drive from Arthur's Pass. This was definitely one of the sketchier mountain roads, but worth the views along the way.
Even though the base of Arthur's Pass is only at 2,500ft (740m), the weather here is much cooler, even in summer. The town is also a main starting point for a number of hikes varying in technicality, from beaten path all the way to fall-line (i.e. "you fall - you die") mountaineering and rock climbing.
We chose the non fall-line option, an out and back hike that took us to a large waterfall called Devil's Punchbowl. The photos of the falls do not do it justice - this is a monster. At 430ft (130m), the force of the water as it surges past you is incredibly powerful. So powerful in fact that this water powers a hydro-electric power station further down in the valley - this is how Arthur's Pass gets its electricity.
The following day we had a plan to spend one of our days near Arthur's Pass exploring one of the two large glaciers on the West Coast (Fox Glacier and Franz Josef Glacier). We had booked a trip up to Franz Josef glacier, starting out with a helicopter flight (#gettodachoppah) up to the ice field, with a guided hike and climb through the crevasses and another heli flight back down. Sadly, the torrential rain meant our activity was canceled...oh well, next time right?
