Hiking guide, Liana Smith's latest adventure involved a three-day tramp to plunge into one of the country's most remote lakes.
Liana took a dip into Otago's Lake Unknown to do her part in a challenge to swim all 344 lakes in the South Island.
She's already an accomplished swimmer having last year completed a 40km swim of Lake Taupo, 22 kms across the Cook Straight swim and a 28km swim of the Foveaux Strait .
She talks to Jesse about her latest challenge!
