Thirlmere Lakes National Park

Part of the Greater Blue Mountains World Heritage Area, this park's five reed-fringed freshwater lakes, abundant with waterbirds and surrounded by quiet patches of forest, are among the last undisturbed lake systems near Sydney and have enormous scientific value.

Only low-impact activities, such as walking, swimming, canoeing and picnicking, are encouraged. Camping is not permitted anywhere in the park and powerboats are prohibited on the lakes.
