Valle de la luna is one of the excursions that you can go on from San Pedro. It is a beautiful valley and the tours usually go in the evening so that you can watch the sunset. It is incredibly beautiful, and the amount of different colors that appear at sunset is amazing. This picture was taken at the top of a sand dune that you can walk up.
The tour cost about 3000 pesos and in general all of the tours charge around the same.
Try to visit the nearby Valle de la Luna for an interesting Atacama desert experience. We took an afternoon/ night tour to el Valle de la Luna with Cactus Tours (cost about $5 USD), which is best visited during a full moon. We stopped at a sand dune in the middle of this unearthly valley to witness an amazing sunset. For best views don't look at the sunset itself, but rather at the red glow reflection it gives to the mighty Andes in the East.
Later that night, we saw a surreal moon rise. I know it sounds weird, but I never notice the moon rising out of the horizon while in a city. Funny what we don't notice while we are at home no? It was beautiful!
In many parts of South America desert areas with bizarre rock formations are called "moon valley" and one could easily imagine that the surface of the moon could look quite similarly ....
My wife and I spent a few days in San Pedro Attacama and one of the highlights was our afternoon crossing the Valle de la Luna. Stunning.
A visit to the Valle de la Luna at sundown is a must, an amazing place. However, it is full of tourists.
A visit to the valley of the moon is usually done around sunset when people climb the sand dune to get the veiws from either side.
