Marsch durch die Todeswüste – Trans Salar de Uyuni

A small expedition sets out to cross the Salar de Uyuni on foot – the world's largest salt flat, lying at 3,600 metres and turning into the planet's biggest mirror at the end of the rainy season. Watch the team head into this unforgiving terrain – but do they realise what they're getting into?

Part 2 of the Salar de Uyuni crossing: at 3,600 metres, the trek continues on foot across the world's largest salt flat, an endless white expanse in an unforgiving environment. But how long can danger go unnoticed out here?

In the final part of their crossing of the Salar de Uyuni, the trekkers push on at 3,600 metres with backpacks and a hand cart across the mirror-like salt flat – while one question hangs over them: what's going on with Beppo? If you're into expeditions in unforgiving terrain, here's where this journey heads next.
