Porongurup National Park , 360 km southeast of Perth protects the Porongurup Range, an extremely ancient and largely levelled mountain range formed in the Precambrian over 1200 million years ago. On a cloudy day we climb Castle Rock, one of its peaks.

We visited Australia on the overland trip from Australia to the Netherlands; see our channel youtube.com/user/JanvanBekkum for hundreds of clips.

Music: "See Mine Own Sweet Jewel" performed by Jon Sayles (jsayles.com/familypages/EarlyMusic.htm#Rights).
