The Mount Aspiring National Park (east of the Divide) area is over 185 000 hectares and stretches all the way from Haast Pass/Tioripatea in the north to the Route Burn in the south, taking in on its way major catchments such as the Makarora, Young, Wilkin and Dart. The forest is predominantly beech, giving way as altitude increases to sub alpine shrubland, snow tussock and glaciated bare rock and snow.

Species present are goats, red deer, whitetail deer and chamois.

Mount Aspiring National Park weather is changeable and wet, dictated by the predominantly westerly moisture laden winds that sweep the Southern Alps/Kā Tiritiri o te Moana.
