We have visited here twice, once when it was hot during the summer and once this last spring.  The spring time was amazing! Granted, it was rather chilly and not a whole lot of people there but it was so quiet and the water was still partially frozen over so the view was incredible from the top of the "boat".  The stars were absolutely incredible to see at night when all the lights were out! Not a lot of trees around so you could see the whole ski!
