After reading about and seeing pictures from the Grampians I included Halls Gap to my travel itinerary. The mountains in the Grampians are not very high, below 1000 m, but they are spectacular. There is a lot of exposed rock (my favourite) and rock hoping or easy climbing is often required to reach the peaks. The highest mountain , Mt William, was actually the least spectacular in the area because there was a paved road all the way to the top which was littered by masts and a humming transformer. But the views and the sunrise from the top still made it worth while to go there.

Mt Difficult, in the centre of the park, was very good. It took about 2 hours to reach the top and that was obviously enough to loose the crowds. Scott, an english guy who I met at the hostel, and I were the only ones there except for the wallaby which escaped as soon as we arrived.

Made it!
My favourite though is Mt Stapylton, a not very famous peak in the northern part of the park. It was not very high in comparison but the rocky peak and the climbing required to get there was just the best.

During my stay in the Grampians the weather was just perfect for hiking. It was around 22 degrees and sunshine. Can it be better?
