Budj Bim National Park is Victoria's first co-managed national park. The park is managed by Gunditjmara Traditional Owners and Parks Victoria.
The park's tranquil crater lake and pleasant bushland surrounds make it a pleasant place for picnicking, camping and bushwalking. Nature trails follow the old crater rim.
