Goes Mansfield (Stowe)>Killington>Ellen>Camels Hump
I thought Ellen and Camel's Hump were tied for 3rd. (Although the true summit of Ellen is actually a bit higher up in the woods to the left of the lift with absolutely no view at all).
One day I'll climb mansfield..
From the base? I've only hiked to the summit of Mansfield from the top parking lot of the Toll Rd. Fun rock scramble up there. Great views, although I think I like the views from the summit of Camel's Hump even better (that one I've hiked from the base of it and was quite a workout).
