An enjoyable and picturesque walk through the Franz Josef Glacier Valley. From the car park its a 1.5 to 2 hour walk depending on how long you stop for photographs. Several waterfalls all around as you make your way to the glacier wall. The Glacier wall itself is quite a way away from the view point as it is receding, though it is still awesome to be so close. Maybe a good idea to keep this in mind so as to not be disappointed. Combine the glacier valley walk with two short walks from the car park (Sentinel Rock for Panoramic views and Peters Pool for reflections) and you have great day out on the west coast. A great FREE way to enjoy you time by the glacier, although you have the options of helicopter tours or heli hikes to get further up close.
Would highly recommend this walk in good weather. If it is raining and you have spare time, I would save it for when you get a break in the weather.
