For well-equipped and experienced hikers, the Dusky Track is an exceptional wilderness experience. The main part of the track links Lake Hauroko with Lake Manapouri, but you can add a detour to Supper Cove in Dusky Sound. To walk the entire track, including the Dusky Sound detour, allow at least eight days.The track crosses mountainous country that rises in places to 1600 metres. The U-shaped valleys were carved by glacial action during successive ice ages. The glaciers and sheet ice have left behind hanging side valleys, horned peaks and high basins that have become lakes. You'll traverse three major valley systems, cross two mountain ranges and find your way along 21 three-wire bridges. You can also expect to encounter tree falls, deep mud, tree roots and river crossings. The forest is predominantly silver beech up to 25 metres tall, with a lush sub-canopy of pepper tree, broadleaf, fuchsia, coprosmas and tree ferns. Ribbonwoods, wineberry, fuchsia and crown ferns surround the clearings. At about 900 metres, beech forest gives way to subalpine shrubland with bog pine, hebes, coprosmas and short tussock grassland. You'll see and hear a wide variety of forest birds, including yellowheads (mohua) and yellow-crowned parakeets (kakariki). Weka and kea usually visit the hikers' huts and kiwi can be heard calling at dusk.To access the track, you can catch a scheduled boat service from Manapouri or Lake Hauroko. It's also possible to fly in or out of Supper Cove or Lake Hauroko.
