I am looking to climb Middle Sister sometime in mid-late June. I understand that one can approach the mountain either from the east or west. Which approach is best, if either, during that time of year? I would like to spend three days on the mountain, so I am also asking for any suggestions for camp areas that might facilitate multiple routes up either North or South Sister, as well. This might not even be possible, as I don't know the area so well yet. Thanks.
