Guided fishing on the Lewis River
The valley of the Lewis River in the Canterbury region of New Zealand, forms the southeastern approach to Lewis Pass. The river runs adjacent to State Highway 7. The Lewis River is a tributary of the Boyle River. The Nina River flows into the Lewis River a few kilometres upstream from the confluence with the Boyle River. The Lewis River was named for the surveyor Henry Lewis, who, along with his colleague Christopher Maling, discovered the pass in 1860. This river holds low numbers of large hard to fool trout.
