Perhaps the crown jewel of the route is the 6 miles of continuous singletrack along the Merrimack River. The eastern half is flat, the western half chocked full of punchy climbs. Sketchy bridges are sprinkled throughout. Most of the terrain flows and begs for speed. My early "master's base" was built riding these trails from work.
These days, I get over there only a few times a year despite being only 25 minutes away by car. It's great for an easy-day ride, like I needed this past Sunday. I brought my "sofa bike," the Santa Cruz Tallboy LTc. Totally overkill for these trails, but bombing down Wood Hill was a blast, almost embarrassing how easily the bike mowed over all the rocks.
