The Twelve Apostles are a collection of limestone stacks off the shore of Port Campbell National Park, offering breathtaking coastal views. The Great Ocean Road provides easy access, with accessible viewing platforms available. Visiting independently is common, allowing flexibility, though guided tours offer deeper insights into the geology and history. Summer offers ideal weather, but it can get crowded; winter brings dramatic seas but cooler temperatures. Viewing is free, but parking and potential park fees may apply. A visit typically lasts 1-2 hours, focusing on the main viewing areas, but longer if exploring nearby trails. Note that only eight stacks remain; erosion is an ongoing process.
