The River Blyth is flowing eastwards (towards the camera) into the North Sea between the village of Walberswick and Southwold.

Fishing boats and pleasure craft can be seen moored along the side of the river where jetties enable the boats to be used even at low tide. There are also repair facilities and stalls selling fish. The river is tidal beyond Reydon marshes towards Blythburgh.

The marshes either side of the river are only just above sea level. The water table at this point is only just below the surface and a network of drainage channels can be seen. The River Blyth has artificial embankments on either side to stop the surrounding land being flooded like in the 1953 floods.
