Mount Greylock at 3491 ft. is the tallest mountain in Massachusetts.. Notch Road from North Adams is the steeper of the two paved roads to the summit, with hairpin turns and some very steep sections in the first half of the climb. I prefer cycling from Williamstown to Lanesborough, then taking the 10 mile ascent on Rockwell Road, built to the summit by the CCC (Civilian Conservation Corps) in the late 1930’s. Both roads were closed for a couple years for total reconstruction and reopened in 2009.
Mount Greylock is the ultimate cycling destination in Massachusetts, with several scenic vistas on your ascent from Lanesborough, and a thrilling roller coaster of a descent back to North Adams or Williamstown on the north side. Dressing for this ride is tricky. On a mild day, you can get quite warm on the climb, but the summit will easily be ten degrees colder than the base. Make sure to take a windbreaker for the descent, and be very careful with those hairpin turns on either side. Avoid weekends during the early fall foliage season when there are many more cars on the roads than usual. The climb from Lanesborough to the summit averages 6% grade, with some sections considerably steeper. Make sure your brakes work for the 6 mile descent on Notch Road.
If you don’t like climbing, you’ll enjoy the 40 mile ride around the mountain taking Rt. 7 on the west and the Ashuwillticook Rail Trail on the east side.
Mount Greylock is closed during the winter and reopens in late spring after the snow has melted.
