A former grazing property, Lonesome was gazetted in 1972 to protect scientific and aesthetic values. It lies along the edge of Carnarvon range and offers spectacular, panoramic views to the southern end of Arcadia Valley, Dawson River, the Carnarvon ranges and mountain spurs.
Brigalow, wilga, lancewood, bottlebrush, native bauhinia and riverine vegetation are prominent throughout Lonesome. One of the few remaining areas of brigalow growing in the red clay soils of the Arcadia Valley is protected within this park. ‘The Candlesticks’ form an impressive sandstone silhouette above the landscape of Lonesome.
