The forest is predominantly beech, giving way as altitude increases to sub alpine shrubland, snow tussock and glaciated bare rock and snow.
The main access points to the area are the roadends beyond Glenorchy, the Wanaka – Mt Aspiring Rd, and the Haast Highway (SH6) in the Makarora region.
Climate
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.
