The Tasman Glacier (Māori: Haupapa) is New Zealand’s largest ice structure, stretching 23 kilometers (14 miles) long and up to 4 kilometers wide along the eastern flanks of the Southern Alps. Originating high near the crest of Aoraki / Mount Cook, the glacier flows south into the Tasman Terminal Lake. Known for its massive upper snowfields, vast depth of up to 600 meters, and dramatic icefall formations, it is the central geographical feature explored during scenic flights, ski plane touchdowns, and helicopter snow landings operated by Mount Cook Ski Planes & Helicopters.

The Franz Josef Glacier (Māori: Kā Roimata o Hine Hukatere) is a 12-kilometer-long maritime glacier located in Westland Tai Poutini National Park on the West Coast of New Zealand’s South Island. Famous for descending steeply from the high snowfields of the Southern Alps into temperate rainforest, it forms a central West Coast highlight during the Grand Circle 55-minute flight by Mount Cook Ski Planes & Helicopters as the flight traverses the Main Divide from Aoraki / Mount Cook.
