Experience 500 year old icebergs up-close on the Mt Cook terminal lake. The Glacier Explorers tour is the only one of its kind in New Zealand - and one of only three in the world! Very few glaciers terminate into lakes and even fewer of them are accessible. See towering ice cliffs and floating icebergs from the safety of a specially designed boat. These boats provide a safe way to view unseen and inaccessible areas of New Zealand's largest glacier - The Tasman.
