Thirlmere Lakes National Park
Park Protected park preserving ancient lakes and heathland
Thirlmere Lakes National Park in New South Wales protects three freshwater lakes amid eucalyptus forest; visitors hike boardwalks, birdwatch and picnic along leafy lake shores.
Thirlmere Lakes National Park protects a pair of freshwater lakes and the surrounding woodland near the town of Thirlmere in New South Wales, Australia. The park conserves lowland wetland and forest habitats atypical for the surrounding region.
The lakes are shallow freshwater bodies set within native eucalypt woodland and provide habitat for aquatic plants and animals of local conservation interest. The site is relatively compact and visited for short nature walks and birdwatching.
The area was designated as a national park to protect these distinctive lake ecosystems and their associated vegetation; specific management actions focus on preserving water quality and native habitats.
The park lies near the township of Thirlmere in Wollondilly Shire, inland from the Illawarra coast and within the greater Sydney-Newcastle region of New South Wales.
