Upper Williamson is the beginning of the easiest way down to the bottom of the Sun Bowl. It is also the beginning to Sunapee's longest trail on the mountian. It starts off the top of Upper Wingding and goes down to its bigger brother Lower Williamson and a bailout trail called Crossover. This is Sunapee's classic New England trail for the novice. All it really is, is a green that is narrow. If you are a novice this is the way to go. A word of Warning: If there hasn't been much snowfall during the year that you ski this trail, don't ski it it doesn't have good cover.
