I had a visitor from WA (our friend).
So, I offered her for a bike ride to south coast line, off course she said "YES" with a big smile on her face.
So, we just went down the Princes Highway, turn off towards Buli, turn left to the Stanwell Tops, chat - chat - chat with few other bikers, then continue down to have coffee in Buli.
On the way back we went straight through the Royal National Park. It was the first time I went up that way and I have to say that I enjoyed every minute of it.
We should do this route sometime soon.
