Williamstown lies on the southern edges of the Barossa Valley on the South Para Road. Until the early 1990's it was a saw-milling town‚ processing timber from the Mount Crawford forests. Today it serves the local farming community and is a stop for tourists making their way to the Barossa through the Adelaide Hills.
The landscaped reserve beside Victoria Creek is a delightful spot to stop for a picnic and a short walk alongside the creek‚ however there are no facilities. An alternative picnic area with playground and facilities is located near the oval. Some six kilometres from Williamstown is the Barossa Reservoir‚ home of the famous Whispering Wall; due to the circular shape of the dam wall‚ visitors can stand at one end and be heard at the other‚ nearly one hundred and fifty metres away.
