Drive south-east of Boulia to the Diamantina National Park. The Worldwide Fund for Nature has named it one of Australia's top 10 National Parks. This 507,000 hectare park is home to many rare and threatened species and the park's rich colours are a photographer's delight. Lake Constance and Hunters Gorge are important wetlands and support breeding populations of many resident and migratory birds. Canoe, bird-watch or take a scenic drive around the park to include the Warracoota Ruins and Janets Leap Lookout. Fishing in the waterholes is permitted and you can catch yellow-belly and Welsh's grunter in the Mundewerra Waterhole. Size and bag limits apply. In the past, Maiawali and Karuwali Aboriginal people moved through every part of this landscape. Their strong spiritual connections remain today. A four wheel drive vehicle with high clearance is necessary as many outback roads are unsealed and wheel ruts can be deep. Take extra fuel, food and water. Open all year however wet weather may cause temporary closures. Visiting is recommended from April to September. Camping is permitted at Hunters Gorge and Gum Hole camping areas (permits are required). For information on permits visit the National Parks website.
