Durville Valley Nelson Lakes National Park
The Sabine and D’Urville Rivers run into the southern end of Lake Rotoroa. The Sabine Valley is part of the popular Travers-Sabine tramping circuit, and as such trampers will be frequently encountered on the tracks and in the huts. The D’Urville Valley is less frequented by trampers, fishermen and is a popular destination for hunters.
Vegetation is mainly beech forest with the lower slopes dominated by red beech, silver beech, and kanuka at sites with poor drainage, and upper slopes by silver and mountain beech grading to pure mountain beech at tree line.
This beech forest ecosystem is transitional from Lake Rotoiti/Travers Valley, which has the drier beech forests of western Marlborough, through to Lake Rotoroa and the Matakitaki where the mixed beech-podocarp forests of North Westland become more prevalent.
