Mount Owen is in the Tasman District of the South Island of New Zealand.[1] It stands at 1875 metres (6150 feet) above sea level and is part of the Marino Mountains. Mount Owen is the tallest mountain found in Kahurangi National Park.[2]
There are a number of caves in the marblekarst areas on the flanks of the mountain, including New Zealand's longest cave system, Bulmer Cavern, which run for 64 kilometres.[3] Mount Owen lies within Kahurangi National Park. The Hope Saddle crosses its eastern flank.
Mount Owen is best accessed via Granity Pass. This generally involves a two-day tramp staying overnight at Granity Pass Hut. It is possible to climb it in winter but care is needed over the karst area due to snow hiding sink holes.
