This morning, visit the Train Cemetery on the deserted outskirts of Uyuni. The town was once a distribution hub for trains carrying minerals on their way to Pacific Ocean ports but in the 1940s the mining industry collapsed, and many trains were abandoned. Spend the morning walking through the old and rusting antique train carriages and steam engines before heading out into Uyuni’s Salt Flats. Explore the lake by 4WD, first visiting the small town of Colchani, where you'll see how the local farm processes salt from the Salar. Then, see the Salt Hotel – this hotel in the heart of the Salt Flats is built entirely from salt! After, discover the cacti and coral-like structures on the rocky island of Isla Inca Wasi before stopping for a picnic lunch in the middle of the salt flats. After, visit the iconic salt sculpture that rises from the endless white expanse – a striking tribute to Dakar Rally (a cross-county rally in all-terrain vehicles). Tonight, if the weather allows, maybe watch the sunset over the otherworldly landscape before heading back to your hotel for the evening.
