Tappy, as the locals call it, was the springboard for legendary mountaineer Sir Edmund Hillary's climbing career that took him to be the first person to reach the summit of Mt Everest.
"I'd climbed a decent mountain at last," Sir Ed said of his weekend solo climb in 1944, while training with the Royal New Zealand Air Force in Marlborough during WW2.
His three-day weekend on Mt Tappy was no mean feat - walking 32km (20 miles) up the Awatere Valley, followed by a long tramp up the Hodder River and a 14-hour climb to the top, before doing it all in reverse on the way home.
The views can be stunning on a good day, but the mountain shouldn't be attempted in bad weather.
The Marlborough Tramping Club's website provides information to climbers and trampers planning to visit the Inland Kaikoura Mountains.
