Fox Glacier is the sister glacier to Franz Josef, located 23 kilometers south. The ice stretches 13 kilometers from Mount Tasman and descends into rainforest. Fox is less crowded than its neighbor while offering similarly stunning experiences. Heli-hike tours allow up to 3 hours or even 7 hours on all-day tours walking on the ice. Nearby attractions include the famous Lake Matheson known for its perfect reflections of snow-capped peaks. Weather is highly variable and staying at least 2 days is recommended.
