Porcupine Mountains. Right on Lake Superior. Waters cold, but the view is magnificent.

Head up to the U.P. Pictured Rock is really nice. It has some nice whiteish sand beaches ..... here is the link to a previous post with some pictures from the trip , I dont think I posted any pictures of any of the beaches though
