Lewis Pass

The pass is the saddle between the valleys of the Maruia River to the northwest in the West Coast Region and the Lewis River to the southeast in north Canterbury. The small spa of Maruia Springs is close to the saddle, on the West Coast side.

Lewis Pass is named after Henry Lewis who, together with Christopher Maling, was the first European to discover the pass, in April 1860 while working as a surveyor of the Nelson Provincial Survey Department.[1][2] Before this time the pass was used by the Ngāi Tahu Māori of Canterbury to transport pounamu (greenstone) from the west coast.[3][4]

State Highway 7 traverses the pass. The road officially opened on Saturday 30 October 1937. It had a regular bus route over it until Intercity's service was replaced by a seasonal shuttle.[5][6][7]

The highway passes through extensive unmodified native beech forest. The area around the pass is protected as a national reserve, the Lewis Pass National Scenic Reserve, which was gazetted in 1981.[8] There are a number of tramping routes in the Lewis Pass area, including the St James Walkway. The short Alpine Nature Walk loop walk around an alpine wetland and tarn is accessed from a carpark near the saddle.
