Barossa Reservoir
Home to the Whispering Wall, Barossa Reservoir is a popular tourist destination north of Adelaide, and just an hour’s drive from the city centre. The reservoir is close to Williamstown and Gawler, just south of the Barossa Valley, making it a great day trip from Adelaide. Pack a picnic and think of a secret to whisper!
