Rewarding throughout.
There was a fresh 6-8 inch snow from the previous night when we got there. Made our last mile a little tricky but it was worth the effort.
You get to see Rainier, Cascades and Olympics from the Glacier Top. This one is so popular because it offers so much within ~12 miles - variations in terrain, majestic mountains, thick glaciers, and more. There were blueberries all around (are atleast a 100), different kinds of mushrooms; we spotted bears in the distant mountains and many cute little Pikas too.
