The north and north-west of Sydney has many waterfalls and cascades. While some have been affected by development, many of them are protected by national parks and bushland reserves. This list of waterfalls in Sydney’s north listed include those in Garigal National Park, Ku-ring-gai Chase and Lane Cove National Park.
Best visited after rain, the Tree Fern Gully Falls is in the Ku-ring-gai Wildflower Garden. The Mueller Track passes the top of the waterfall, and an informal pad leads to the base.
