Southwold Harbour lies south of the town on the River Blyth. Vehicle access is via York Road and Carnsey Road to the west and Ferry Road to the east. The harbour extends nearly a mile upstream from the river mouth and is mainly used by fishing boats, yachts and small pleasure boats. The clubhouse of Southwold Sailing Club is on the north side of the harbour adjacent to "The Harbour Inn". The quay and area in front of the inn and clubhouse is called Blackshore; although the name has often been used incorrectly for the whole harbour in recent years.
