Whispering Wall

Otherwise known as the retaining wall of the Barossa Reservoir, Whispering Wall has attracted attention across the globe. But why? It's unique acoustic effect allows whispered words to be carried more than 100 metres away to be clearly heard at the other end. Children love visiting Whispering Wall to test out its truly amazing characteristic, with the bush surrounds ideal for a picnic overlooking the scenery of the water reserve.
