La mejor temporada para venir es por estas fechas, ya que como es temporada de lluvias veras el espejo mas grande del mundo y podrás disfrutarlo al máximo. Aora el como venir es dependiendo si es por el sur o por el norte debes especificar

Well you can take a bus from la paz to uyuni, it's better if you go with somebody from Bolivia, cuz if they see you aren't from here they are going to charge you more. When i went there they start asking for about 500 bs for people (71 $ ) and asking in several places the same agency cut the cost to 250 bs (almost 36$) for a tour of two days with transport and lunch.

you should look for the rainy season here in Bolivia, and specially in uyuni cuz thats how you can take those photos where the sky blend with the floor.
