Is there anything more impressive than Mount Rainier during sunset? Don't answer because I know the answer. BUT, it surely is a sight anytime the mountain is out.
I remember reading at some point that Rainier is only visible 30 days out of the year but I don't think that is true. At least not from Seattle. But I've been to this same spot and you wouldn't guess that it is there when engulfed by clouds and fog.
