South Dandalup Dam

The largest of all dams supplying Perth, South Dandalup Dam is a popular destination all year for its tall trees, rich birdlife, and close proximity to the historic timber town of Dwellingup.


Please note: There are some instances when our dam recreation areas will be closed, particularly in summer when there may be a bushfire risk. Before planning a visit to one of our dams, phone us 24 hours on 13 13 75 or check our Facebook page for a post about dam closures.

What to do?

There is nothing like a country picnic amongst WA’s jarrah trees. Have lunch, use the free gas barbecues, and set up at a table in the picnic area located at the top of the dam wall.

Enjoy the spectacular view of the dam at the lookout. 

For bird lovers, there is an abundance of native species to find, including robins, finches and blue wrens. You might also catch a glimpse of a kangaroo or wallaby.

Take gorgeous photos of the colourful flowers during wildflower season from July to November.
