Palacio de Sal, Bolivia
Do not go near the Palacio de Sal if you want to reduce your sodium intake. This place is pure salt, the walls on the ground through the furniture.
Color chalk white huts blend into the white landscape of the Salar de Uyuni, which extends to a salty drop in all directions and provides a breathtaking view for stargazing and eating popcorn. Or fries, or chips ... you get the point. It is a land of salt, lots of salt.
