We left Potosi in the morning; quickly the road became a bumpy dirt road, no good outlook for this six hours bus ride.
However – as soon as we left town also the scenario opened, revealing amazing views and more amazing views, some reminding me of the Grand Canyon, others of the Black/White Desert in Egypt, others of the area around Lake ErHai near Dali, China (except for the lake, of course). To summarize – for me it was the most amazing bus ride so far, independent from the road condition.
