Sawcut Gorge, Isolated Hill Scenic Reserve

A spectacular narrow limestone gorge in the Ure (Waima) River valley in south Marlborough, where the walls are only 2 to 3 m apart and rise about 50 m high. The walk from the road end follows the riverbed and takes about 2 to 3 hours return, crossing the river many times, so expect wet feet: go in summer, when the water is low and warm.

It's isolated and rarely busy. Don't go during or after heavy rain, when the river rises quickly. For an overnight trip, the six-bunk Ure Hut is about an hour further up the valley.

To get there, turn off State Highway 1 about 15 km north of Kekerengu, cross the railway line and follow the gravel Ure Valley road to the road end at Blue Mountain Station. Ask permission at the station.
