Twin Falls was the first commercial via ferrata installed in New Zealand, bolted into the schist face of the Matukituki Valley in 2011. The route ascends sixty-five vertical metres alongside a permanent waterfall fed by snowmelt from Mount Aspiring, the country's third-highest peak. Steel rungs, cable staples, and a continuous steel wire anchor the path — a system borrowed from Dolomite alpine passages but adapted to the slick, moss-covered rock typical of Southern Alps gorges. The wanaka waterfall via ferrata tours operate year-round, though winter months bring higher flows and colder spray. Wildwire Wanaka, the sole operator licensed to guide on this route, maintains the hardware quarterly and replaces corroded sections after each Southern Hemisphere winter. The climb requires no prior technical skill but demands steady footing on wet rock and comfort with exposure; at the crux traverse, the valley floor drops away forty metres below your boots. The route's design prioritises intimacy with the falls. Unlike dry via ferrata elsewhere in the South Island, this line crosses behind the main cascade twice, threading between the rock face and the curtain of water. Climbers wear full-body harnesses connected to the fixed cable via twin lanyards and shock absorbers — the same gear used in European alpine routes. Helmets are mandatory; spray from the falls keeps every surface damp from September through March. The broader Mount Aspiring region, a UNESCO World Heritage Area since 1990, protects over three hundred fifty thousand hectares of beech forest, glacial valleys, and alpine tundra. Twin Falls sits at the valley's threshold, accessible via a twenty-minute drive from central Wānaka along the unsealed Wanaka-Mount Aspiring Road. The route's popularity has grown steadily since its opening — advance booking is now standard practice during the December-to-February summer peak, when daily sessions often reach capacity.
