Mount Barney National Park, Nature reserve in Scenic Rim Regional, Australia.

Mount Barney National Park is a nature reserve 90 km southwest of Brisbane whose twin peaks, Mount Barney's East and West peaks, rise to 1359 m above surrounding farmland. The park also holds Mount Maroon, Mount May, Mount Lindesay, Mount Ballow and Mount Ernest, with steep valleys, caves and deep rock pools. More than 30 routes lead to the summits.

The park formed from volcanic activity millions of years ago, with lava flows and erosion shaping the current mountain forms. This geological history created the steep slopes and weathered peaks visible today.

The park lies within the Gondwana Rainforests of Australia, a UNESCO World Heritage Site since 1994. Its subtropical rainforest above 600 metres shelters the vulnerable marbled frogmouth, while the endangered Maroon wattle and the mallee eucalypt Eucalyptus codonocarpa grow in the park. BirdLife International identified the Scenic Rim as an Important Bird Area for threatened birds.

The trails cross rough terrain and require endurance along with hiking experience. Visitors should bring plenty of water, sturdy footwear, and a map while being prepared for changing weather.

The first recorded ascent of Mount Barney was made in 1828 by Captain Patrick Logan, who climbed via the ridge now bearing his name. His companions, Allan Cunningham and Charles Fraser, did not reach the summit. The park also protects the vulnerable marbled frogmouth, a bird that relies on the rainforest on the mountain.
