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.
St Ives Wildflower Garden
Ku-ring-gai Wildflower Garden is a 123-hectare botanical garden in St Ives, in the north of Sydney. The Garden was established in 1966 by John Wrigley on behalf of Ku-ring-gai Council, and all of the plants in the Garden are Australian natives. There is a nursery within the Garden where plants can be purchased, many short bushwalking trails, multiple picnics areas and a pavilion (Caley’s Pavilion) which can be booked for functions.
