So, we're in the middle of nowhere, in the driest desert in the world. Yet despite the dust and lack of water, it's absolutely beautiful and it's best place on Earth to see the stars!
The temperature contrasts massively between day and night, when it plummets from 27C to -15C. One (very Chile) evening we went right into the middle of the desert to a local astronomer's house to learn about the stars and the sky before gazing at them through his ten huge telescopes. The night's sky was the clearest we´d ever seen and the sky was FULL of twinkling stars! He took amazing pictures of the moon with our cameras, but Jo went one better and managed to get a pretty snap of Saturn too! Afterwards we sat round and drank hot chocolate as he explained why we won't be visited by extra terrestrials any time soon (sorry dad!)
The next day we took a trip to Valle de Lunas (valley of the moons) and a local guide explained the complex geology of Chile and the Andes by drawing us diagrams in the sand! He took us to loads of impressive viewpoints (including Death Valley!) where we saw where the mountains that divide Argentina, Bolivia and Chile. The best bit was when we saw the sun go down over the mountains, watching the sky turn from blue, to orange, to pink to purple within a matter of minutes...
Our last day coincided with Fiesta de San Pedro, an annual festival where the town celebrates its history with colourful processions through the streets. A great way to finish our time in Chile!
