Middlesex Fells Reservation, MA. Rock Circuit Trail: 5 miles roundtrip loop Easy to Moderate As with last weekend, I didn't feel like driving up north for a hike. The temps here were colder and it was more windy than a week ago. But the short ride to the Middlesex Fells Reservation suited me just fine. Plus, it was a distraction for the time being - while I wait and hope for more ice to re-form in the Kinsman and Crawford Notches. I had hiked part of the Rock Circuit Trail (white blaze) before, but just from Pinnacle Rock to White Rock. Today I parked at fire gate #53 and hiked counter-clockwise starting at fire gate #52. As with last weekend, there were many hikers and dogs but not a single biker on the trails of the Eastern Fells. Blog & video of last weekend's solo hike along the Skyline Trail here . Enjoy some photos taken along my hike.
