How’s this for dirty work?
Heading off to work at the salt mine each day … by bike.
Elevation 3.65km (2.26mi) high. Thin air. Shadeless. No water. Freezing cold or scorchingly hot.
Don’t forget your pick and shovel.

For me and most travellers, the most memorable highlight of travel in South America are the salt flats of Uyuni in Bolivia.
