River Blyth, Suffolk

For articles about other rivers named River Blyth, see River Blyth (disambiguation).

The River Blyth is a river in Suffolk, England, with a tidal estuary between Southwold and Walberswick.

It can be crossed by pedestrians by a public footbridge called the Bailey Bridge about a mile upstream from the sea or by the Walberswick rowing boat ferry between 9am-5pm daily.

The estuary mouth forms the main harbour area of Southwold and is still an active fishing harbour.

The estuary is central to the plot of Peter Greenaway's film Drowning by Numbers, being the scene of the final drowning.
