Glacier Explorers

Details

The only tour of its kind in New Zealand and one of the only accessible glacial lakes containing icebergs in the world. An amazing encounter with New Zealand’s largest glacier, the Tasman Glacier.

Explore and learn about the ever-changing glacial landscape as you journey across the terminal lake in our custom-built MAC Boats with your experienced guides. Icebergs of every shape and size periodically tear away from the face of the glacier into the rapidly growing lake. Lateral moraines rear up almost 200m to remind us of the scale and greatness that the glacier has reached in previous times.

With the effects of global warming and other climatic processes taking their toll on New Zealand glaciers, their retreat is imminent. Now approximately 27km long and 600m deep, the Tasman Glacier is melting and calving at an exponentially increasing rate. In recent years the Tasman Glacier has changed from a ‘melting’ to a ‘calving and melting’ terminus, resulting in a terminal lake that is rapidly increasing in size.
