There are a few short walks you can do accessed on the road that runs through the middle of Grampians National Park (C222). We did a couple at the popular MacKenzie Falls, and also a short walk to the Balconies. It was hazy when we got to the Balconies and so this rather impressive area did not look its best in my photos, so I’ve included just the one. MacKenzie Falls is an impressive waterfall that is somewhat a victim of its own success. Worth the visit nevertheless, (but don’t swim too close to the waterfall because people have drowned there). The tracks are constructed and obvious.
There are short walks to MacKenzie Falls and the Balconies that are easily accessed off a major road through the Grampians (C222). Both areas are popular with tourists so don’t expect serenity. They are justifiably popular, and not just because they are easy to get to.
