Northern Cape > South Africa > Africa June 24, 2011 - 4.5 I did this ride while circumnavigating South Africa. Hardly any traffic, the Anenous pass makes things interesting, while the wide open sections are ideal for checking top speed. I saw 263 km/h on my Garmin. Some restaurants in Port Nolloth. Take a jersey, the temperature drops quite drastically as one approaches the ocean.
Gauteng > South Africa > Africa January 17, 2011 - 4.0 A nice drive through the cradle of human kind. Some nice long(ish) corners, the road is wide and open with no potholes etc. A nice short ride to Magalies.
Western Cape > South Africa > Africa August 15, 2007 - 4.3 The scenery is tops, the asphalt is super and the roads are winding and hilly.
The weather was brilliant when I was there end November 2004 (blue skies and ~ 25 degrees...!).
Recommendation: Rent a large trailie so that you can go down one of the many gravel or dirt roads to the beaches if you like.
Western Hungary - Budapes... > Hungary > Europe January 29, 2011 - 4.3 A very winding road from the beautiful Pecs to the lakes in Orfü.
One curve follows the next. The road crosses a hill but it is not too steep.
