Located near Reefton the Grey River/Māwheranui runs through native beech forests, steep gorges and farmland for 120 kilometres before meeting the Tasman Sea at Greymouth.

Heading towards Springs Junction from Reefton in the Inland Adventures van it takes an hour to reach the start of the multi-day trips on the Grey River.  

An hour's drive south of Reefton takes us inland from Ikamatua to commence the one day tour on the Grey River.

Much of the scenery on these trips is difficult or impossible to access from anywhere but the river. What you experience is truly unique.

Waiau-uha begins in the Spencer Mountains. This mountain range forms a natural border between the East and West Coast of the South Island

Located near Hanmer Springs and the Lewis Pass the Waiau-uha river flows through the St James Conservation Area and the Glen Hope Station out to the Lewis Pass road where it is joined by the Hope River.

It takes just under 2 hours in the four wheel drives to reach the starting point of the 3 day adventure up towards Lake Tennyson. To reach the starting point for the one day and 2 day tours again it takes just under 2 hours from Hanmer to reach the river driving towards the Lewis Pass and through Glen Hope Station.

The Waiau-uha is stunning, with rough East Coast landscapes of towering mountains, narrow gorges, tussock valleys and pure clean water.

The Arnold River drains out of Lake Bunner and enters the lower part of the Grey River near Stillwater. The river water is seldom discoloured, with sections of the river bank covered with native forest and willow trees over hanging into the water in other areas. 

A short drive from Greymouth, having friendly Grade 2 rapids and less than 90 minutes on the water makes the Arnold River trip an entertaining experience for the whole family.
