Kinglake National Park is closed due to the February 2009 Black Saturday bushfires. Approximately 98% of the park, including the office and most visitor facilities, were completely burnt.
UPDATE (April 2010): Currently all of the walking trails are closed in the park. Masons Falls Picnic Area and Mt Sugarloaf Picnic areas are also still closed (although the road to Mt Sugarloaf is open).
UPDATE (Jan 2013): The Masons Falls area has just been reopened to the public. The Masons Falls Circuit (12.6km) is not open however as the Running Creek section of the trail is still currently closed.
