Trailhead: Wheelerville Road off Route 4 in Mendon, Vermont (at Brewers Corner). Road was closed due to a washout so we continued on Route 4, taking a left at the Mendon Best Western, then turning on to Notch Road - which will get you to Brewers Corner. (Note 2014 - bridge has been repaired and road is in good shape.)
Lesson learned: Not all trails in New England are rocky, rooty and arduous!
In actuality, Mendon, VT is not on the way home but 30 minutes west from I-89 got us to the trailhead, not without some problems. We got to where the car GPS and GoogleMaps said Wheelerville Road was and it simply was not there! Asked a neighbor and he indicated it was actually the next road down. Got to that road and yes it was Wheelerville Road but it was closed about 1.7 miles in, 2.2 miles from the trailhead. Thanks to Dana, we got back on Route 4, turned left at the Mendon Best Western, found Notch Road which lead us to the other side of Wheelerville Road.
The top of Killington Peak provided the most magnificent of views. It was quite crowded at the top, being an excellent day for hiking and sight-seeing and mountain biking (the Killington chairlift nearby was running, bringing guests and cyclist up to the peak).
