The pristine waters of Thirlmere Lakes National Park provide the perfect sanctuary for more than 140 species of birds, which can be spotted in and around the area. As you’re walking along the Thirlmere Lakes track, keep an eye out for waders and waterfowl. Other birds you may encounter while you’re exploring include the white-faced heron, musk duck, pacific black duck pied cormorant, Australasian grebe, and white-bellied sea eagle.

Formed over millions of years from the effects of weather and erosion, the majestic Hawkesbury sandstone which surrounds Thirlmere Lakes is a sight to behold. With sandstone plateau slopes which meander downward from the east and west, meeting in the middle to form Blue Gum Creek, the water rolls perfectly down into this idyllic spot where you can swim and go paddling.

Water from the lakes was once pumped to Couridjah to replenish steam train locomotives on the old southern railway line. Historically significant remnants of this era remain in the park, including the restored sandstone Heritage Pump Station and the pump housekeeper’s track.
