The Siloli Desert is located at 4,500m above sea level and is favourite destination for many of our tour packages to Bolivia
. The Andes are part of the desert, which is covered in volcanoes and ridges. The desert road is made up of gravel and sandy roads. The road follows a series of rocks that were formed by strong winds. Arbol de Piedra, also known as Stone Tree, is the most stunning. Because it looks like a tree, this unique volcanic rock formation is very special. Another surreal scene is the beautiful, coloured volcano that dominates the western horizon.
