Located in Tararua Forest Park in the Wairarapa and Wellington/Kapiti regions
The Southern Crossing is one of the four classic tramps of the Tararua Range.
Originally it was the route from Otaki Forks to the Wairarapa Plains (and in later years, the Kaitoke Basin). It was popularised during the 1920s and 30s by the Tararua Tramping Club and other clubs in the Hutt Valley and Wairarapa.
