The Great Otway National Park, also called The Otways or the Otway Ranges, is a national park in Victoria (Australia), 162 km southwest of Melbourne. It contains a diverse range of landscapes and vegetation types.
Lake Elizabeth, formed from a landslide in August 1953, it broke its banks allowing the West Barwon River to flow.
The 103 km² park was declared in 2004 when Otway National Park, Angahook-Lorne State Park, Carlisle State Park, Melba Gully State Park, areas of the Otway State Forest and a number of Crown Land reserves were combined into one park. The parks were combined after a campaign by the local community and the Otway Ranges Environment Network.
The park is a popular area for interstate and international tourists, with companies operating tours in the region. It contains three camping areas at Johanna, Aire River and Blanket Bay. The park is accessed from the east via Apollo Bay, from the north via Forrest or Beech Forest, or from the west via Princetown. The park covers both coastline and hinterland in the Otway Ranges and so includes both beaches and forest, accessible via walking trails. The Cape OtwayLighthouse is adjacent to the park and is open to tourists throughout the week. The park and the Aire River campground are home to a significant koala population.
