A good stop to stretch your legs, if you are heading North from Denmark, is the Granite Skywalk. A 4.4 km return hike up 282 meters incline through the Porongurup National Park. During the bushwalk you can enjoy the vegetation or admire the massive granite boulders that nature has created. These rocks are, and have been for millions of years, in an eternal balancing act that started with a crack and rain drops running through them; until eventually they are what we see today.
At the top of the hike you have a choice of two lookouts. The upper lookout perches over the side of Castle Rock and requires scrambling over and under rocks and climbing a rattling ladder. The lower lookout, the Karri Lookout, for those who are not comfortable with the adrenaline pump to go up to the upper lookout. Both offering amazing views of the region and a healthy dose of cold wind blowing in your face.
