National Parks and Reserves

Built between 1899 and 1903 the Whispering Wall is part of the dam wall located in the Barossa Reservoir Reserve and is known for its unique acoustic effects. Words whispered at one side can be clearly heard at the other, more than 100 metres away.

Barossa Reservoir Reserve 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!

Free car parking and toilet facilities are also available.

Open 8.30am – 5pm (standard time), 8.30am – 6pm (daylight saving time). Closed on Total Fire Ban Days and for operational activity (gates will be closed).
