The best beach is la Ensenada, if you can get there.. From santiago head to La Linea, then go to 'el cruce de guayacanes' (I think that's the name). Last time I was there in 2003, the road was not in good condition, but once you get there, this place is a piece of heaven. The sand, the water !!. Perhaps my dear friend, HB can add more to this.. HB, please help !!!!
