The Ball
Shelter Track, part of the Ball Hut Route, leads along the western side of the glacier, separated from Tasman Lake by a tall moraine wall until about 6 kilometres in, where it climbs high enough for the view to open up. At that point, the rock-covered lower Tasman Glacier in the valley

The glacier remained at a constant 28 km (17 mi) in length for all of its recorded history in the 20th century before starting its current period of rapid melting in the 1990s. Between 2000 and 2008 alone, the glacier terminus receded 3.7 km. Since the 1990s the terminus has retreated

Similarly, Tasman
Glacier's significant ice loss over the past decades has impacted tourism, with an increasing number of crevasses being exposed and not filled in by snow any more, requiring guided tours to avoid these areas, and restricting the heli skiing season to July, August and September.

Tasman
Glacier has a long history of tourism, with heli skiing tours offered on the upper glacier since the early 1970s. The tributary Ball Glacier was also popular for skiing, with national championships being held there in the 1930s. It has since diminished too far to be safely accessed.

about 180 metres (590 ft) a year on average. The glacier is now in a period of faster retreat where the rate of retreat is calculated to be between 477 to 822 metres (1,565 to 2,697 ft) each year. It is estimated that the Tasman
Glacier will eventually disappear and the terminal

At 23.5 kilometres (14.6 mi) in length, Tasman
Glacier is still New Zealand's longest glacier, despite shrinking considerably from the 1990s onwards. It is as much as 4 kilometres (2.5 mi) wide and 600 metres (2,000 ft) thick, and lies entirely within the borders of

The proglacial Tasman Lake is a popular destination for boat tours among the icebergs often floating in the lake. Boats are not allowed closer than 1.5 km (0.9 mi) to the 50 m (160 ft) tall terminal face of Tasman
Glacier for safety reasons.
