100km from La Serena sits Elqui Valley (geez, I read too many guide books), where, it is claimed, is the best sky to watch the stars. Also UFO has been seen in the area, so a lot of hippies moved here in the 60s. Stars are great here, but I cannot see huge difference with Olmue. I would say, I liked Olmue better than here, but there I lived on the top of the hill and could see all valley, here I am at the bottom.
P.S. As I forgot to write in Spanish last week, there will be 2 Spanish posts for this.
