Just finished a thru hike last Monday- I'd definitely recommend anywhere the trail goes above 4 thousand feet.
White rocks is cool, and has a nice waterfall.
Stratton is cool, and I was a fan of the section from Stark mtn to Sugarbush. Also some cool boulder caves on Stark.
Also avoid the gortex with whatever you get. I use ankle supports when I do anything longer than 20 miles like these
