The Dusky Track covers 84km (including an out & back section to Supper Cove) between Lake Hauroko and Lake Manapouri in Fjordland National Park on the South Island of New Zealand. It is normally walked in 8-10 days. The NZ DOC cautions trampers:
"This difficult tramping track between Lake Hauroko and Lake Manapouri offers huge lakes, gushing rivers, vast forested valleys and lots of mud for experienced and well equipped trampers.
- It crosses three major valley systems and two mountain ranges.
- Offers fantastic views over a vast Fiordland landscape.
- Is difficult but rewarding."
