Grampians National Park, a renowned natural wonder in Victoria, Australia, offers stunning landscapes, abundant wildlife, and rich Indigenous cultural sites. Primarily accessible by car, visitors can explore numerous lookouts, waterfalls, and diverse hiking trails, ranging from easy strolls to challenging multi-day treks like the Grampians Peaks Trail; while some areas offer wheelchair accessibility, many trails are rugged. The park is suitable for both solo adventurers and guided tours, with the latter providing deeper insights into its heritage and ecology. Best visited in spring for wildflowers or autumn for mild weather, though it's open year-round; summer can be very hot with bushfire risks and potential closures, and winter is cooler and wetter. Entry for day visitors is typically free, with costs mainly encompassing transport, accommodation, and optional activities, and a typical visit can last from a single day to 3-5 days for a comprehensive experience. Essential tips include booking accommodation and camping in advance, especially during peak seasons, carrying ample water, and being aware of bushfire season closures and patchy mobile reception.
