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 are closed, particularly in summer when there may be a bushfire risk. We endeavour to update our website should this occur, but it's a good idea to check the emergency.wa.gov.au website for any National Park closures before planning a day out – if the park is closed, the dam areas will be as well.

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.
Why not visit Dwellingup while you’re here? Only 8km away, it offers charming craft shops and a Forest Heritage Centre for you to browse.
