Walberswick Common Carpark.

Large carpark next to the river, some pubs and eateries but not much in Walberswick its self. Nice spot to just chill or if your feeling energetic walk up the river and cross over into Southwold via the old railway bridge, the Southwold to Halesworth was a narrow gauge line (3') which closed in 1929. https://www.southwoldrailway.co.uk/history/
You can also take the foot ferry across the river where you will be rowed across in a small rowing boat.
