The star of the stargazing show, the purpose-built Observatorio Cerro Mamalluca, 9km northeast of Vicuña, is Elqui Valley's biggest attraction. So big, in fact, that you're likely to share the tour with hordes of other tourists, all looking for their chance to goggle at distant galaxies, star clusters and nebulae through a 30cm telescope.
