The Opihi River rises in the foothills of the Two Thumb Range and flows east across the Canterbury Plains to the sea between Temuka and Pleasant Point. It is one of the better brown trout rivers in Canterbury, known as a classic dry fly fishery with clear water over gravel runs, and it also produces salmon near the mouth in late season. Whitebait runs the lower reaches in spring. The river serves as a practical recreational corridor, with the stop bank walkway between Temuka and Pleasant Point offering a long, flat route suitable for walkers, cyclists and families, plus accessible swimming holes along the way.

About the Opihi River
The Opihi River flows through farmland and riparian areas of South Canterbury, providing a mix of angling opportunities and easy riverside recreation close to Timaru. Its clear waters and gravel-bed structure support a reliable population of brown trout averaging over 1 kg, with better fish often found in the upper reaches and deeper pools.
The lower river and mouth area attract anglers for a modest run of quinnat (Chinook) salmon in autumn when conditions allow. Whitebait fishing is popular in the lower reaches during the regulated season from 1 September to 30 October.
The river corridor also supports family-friendly activities beyond fishing, with the stop banks providing level paths that connect communities and offer spots for picnics or cooling off in summer.
Fishing
The Opihi has a reputation as one of the more reliable brown trout fisheries in South Canterbury. The river holds reasonable populations of smallish to medium brown trout throughout its length, with better fish in the upper reaches and in pools below the main gorge sections. It is well suited to dry fly fishing with classic riffle and pool structure and clear water that rewards careful presentation. The lower river and mouth area can produce quinnat salmon in autumn when conditions are right, and whitebait fishing is popular along the lower reaches from 1 September to 30 October each year.
The Opihi Walkway
The Opihi Walkway runs along the stop banks of the river between Temuka and Pleasant Point. It is a flat, easy route of around three hours one way that follows the river through farmland and riparian areas. The walkway is one of the longer routes in the district and connects two towns, making it suitable for a point-to-point trip with a vehicle shuttle or as a return walk from either end. Access is available from Arowhenua Road near the Temuka bridge and from Pleasant Point.
Swimming in the Opihi River
Swimming holes along the stop bank route provide opportunities for a refreshing dip, especially during warmer months. Visitors should always check current water quality notices before entering the water, as river conditions can change quickly after rain. The flat, accessible paths make these spots suitable for families seeking a relaxed riverside outing.
What Visitors Often Say
