The Keglsugl route involves climbing up and through a mountain rain forest and then along an alpine grassland glacial valley to the twin lakes of Piunde and Aunde. At Piunde there are two huts, one being an old Australian National University monitoring station and the other an 'A-Frame' hut. Though not a technical climb, various sections can be treacherous in wet weather. The climb is usually started during the night; the ascent and subsequent descent can take anywhere from nine to 24 hours. Reaching the peak at dawn allows a better chance of clear weather.
