Can you walk on Franz Josef Glacier?

Glacier walks on the ice surface are accessed by helicopter, not on foot from the valley floor. The valley floor walk takes you to the terminal face viewpoint but not onto the ice — the glacier has retreated significantly and the terminal face is now unsafe to approach on foot due to rockfall and ice calving risk. Helicopter glacier walks are the main way to step onto the ice. Half-day heli-hike experiences operate from both Franz Josef and Fox Glacier villages.

Why are the West Coast glaciers so unusual?

Franz Josef and Fox glaciers are remarkable for their combination of altitude range and latitude. They descend from the main divide of the Southern Alps — where the neve (snowfield) sits at around 2,700 metres — to valley floors once close to sea level. This means the ice flows through a full climate gradient, from alpine conditions at the top through subalpine to temperate rainforest at the bottom. Very few glaciers in the world at this latitude reach such low elevations, and even fewer do so through native forest.

Are the West Coast glaciers retreating?

Yes. Both Franz Josef and Fox glaciers have retreated significantly over the past century. There have been periods of advance — notably in the 1990s and early 2000s when both glaciers advanced substantially — but the overall trend is retreat, consistent with global patterns. The terminal faces are now considerably higher up the valley than they were in the mid-20th century. The valley-floor walks to the viewing areas have lengthened over time as a result.

Which is better — Franz Josef or Fox Glacier?

They are similar in character. Franz Josef village is slightly larger with more accommodation and tourist facilities. Fox Glacier village is quieter and has the advantage of Lake Matheson nearby — a still reflective lake in the forest that produces famous mirror reflections of the mountains on calm mornings. If you're visiting both anyway (they're about 25km apart), start at Fox Glacier in the morning for Lake Matheson, then continue to Franz Josef.

Franz Josef and Fox Glaciers: Where Ice Meets Rainforest

On the West Coast of the South Island, two glaciers flow down from the main divide of the Southern Alps through dense temperate rainforest. Franz Josef Glacier and Fox Glacier descend from snowfields at around 2,700 metres through a full gradient of climate zones — alpine, subalpine, and finally temperate rainforest — to valley floors that once sat close to sea level. The combination of active glaciers and lush forest in the same valley is unusual enough to be considered among New Zealand's most distinctive landscapes.

What Makes the West Coast Glaciers Unusual

Ice and rainforest in the same valley

Most glaciers at comparable latitudes exist at high altitude, above the treeline. The West Coast glaciers are unusual because New Zealand's Southern Alps intercept extraordinarily heavy westerly rainfall — creating both the thick snowfall that feeds the glacier and the lush rainforest that fills the valley below. The result is an ecosystem where you can walk through mature podocarp forest and then look up the valley to ice moving between vertical rock walls. At their greatest historical extent in the 19th century, the glaciers descended very close to sea level through the forest.

Accessing the ice today

Helicopter required Heli-hike options

Both glaciers have retreated significantly and their terminal faces are now higher up the valley than they were even 30 years ago. Valley-floor walks lead to terminal face viewpoints — clear ice and rock walls — but you cannot walk onto the glacier from below due to instability and rockfall risk. Accessing the ice requires a helicopter. Half-day heli-hike experiences operate from both Franz Josef and Fox Glacier villages: a short flight up to the glacier surface, around two hours guided on the ice with crampons, then a flight back. It is the most dramatic way to experience either glacier.

Lake Matheson: the mirror lake

Fox Glacier Early morning

About 5km west of Fox Glacier village, a walking track circles Lake Matheson — a small lake formed in a hollow left by a retreating glacier. On calm mornings the surface reflects Aoraki/Mount Cook and Mount Tasman perfectly in still water. It is one of the most photographed views in New Zealand and earns its reputation on a windless day. The walk takes about 1.5 hours and is at its best in the first hour of daylight before any wind disturbs the surface.

Weather and flexibility: The West Coast receives some of the highest rainfall in New Zealand, which can shut down helicopter operations for days at a time. If glacier walking is a priority, build flexibility into your schedule — at least a day of buffer. The valley-floor walks and Lake Matheson are worth doing regardless of conditions and remain accessible in most weather.

The Two Villages

Franz Josef village (population roughly a few hundred permanent residents in the off-season) is the larger of the two, with more accommodation, restaurants, and tour operators. Fox Glacier village is smaller and quieter. The two are about 25km apart via State Highway 6, making it easy to visit both in a single day if you have a vehicle. The drive along the West Coast between them passes through some of the most dramatic mountain-meets-coast scenery in the country.
