Full of educational, historical and natural attractions, Mundaring Weir is both a vital source of water for Western Australia and a lovely place to visit.
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.
