Running from Kaiuma Bay near Havelock, to Duncan Bay in Tennyson Inlet, the Nydia Track is one of the lesser-known walks in the Marlborough Sounds.
The 27km shared-use track that follows old bridle paths can be tackled on either foot or mountain bike over a couple of days.
Winding through regenerating bush and impressive podocarp and beech forest, the Nydia Track includes coastal landscapes with stunning views over the Kenepuru Inlet.
The landscape of the Marlborough Sounds is unique as it’s the only area in New Zealand where the landmass, weakened by several fault lines, is slowly sinking into the sea.
Steep climbs to the track’s saddles, slippery paths even in summer, and technical rocky sections mean this trip is best suited to experienced trampers and riders.
