Sun Valley

Sun Valley is a tranquil semi-rural enclave in the lower Blue Mountains of NSW, prized for its ancient geological origins and scenic bushland.​ History Sun Valley sits atop a rare volcanic vent, or diatreme, dating from the Jurassic era—a striking feature amid the otherwise sandstone-dominated mountains. The area was inhabited by Dharug and Gundungurra peoples for thousands of years, with stone artefacts, axe grinding grooves, and cave art testifying to a long history of occupation and tool-making. Early European explorers, including Blaxland, Wentworth, and Lawson, camped here during their 1813 crossing, and the valley quickly became a vital stopover for travelers and road builders in the 19th century. Later, the area was used for grazing, farming, and timber-getting, and subdivided for residential living in the 1960s, giving Sun Valley its current name.​ Population Sun Valley today is home to a small, close-knit community living on rural acreages, reflecting its origins as a market gardening and farming zone. The population remains modest, underpinning its peaceful, semi-rural character.​ Attractions The valley is renowned for bushwalking tracks through Long Angle Gully, remnants of early farming and timber-getting days, and stands of mountain blue gum, including those named for botanist Henry Deane. Paradise Pool—a historic swimming spot—is popular with locals, while the Sun Valley Pony Club, produce store, and fire trails contribute to community life.
