Air Safaris operate a 50-minute scenic flight from Lake Tekapo that takes in the braided river systems of the Mackenzie Basin, Aoraki/Mount Cook and Tasman Glacier in Aoraki/Mount Cook National Park and Franz Josef and Fox Glaciers in Westland Tai Poutini National Park.
They also operate the same flight from Glentanner Park (near Mount Cook), but it is cheaper to take the flight from Lake Tekapo. The flight costs $370.
