The first 2 1/2 miles or so of the trail (from Westminster Road at the base of Mt. Wachusett to rte. 62) ran almost entirely across the Mass. Audubon Society's Wachusett Meadow Wildlife Sanctuary. The trail was pretty well marked, and the sanctuary includes a number of different styles of terrain, including some areas of dense pine forest, some more open hardwood forests, and a couple of meadows.
While the forested areas are nice to hike through, especially when it is warm, I wish there were more meadows like this one along the trail. I also wish there was less on-road hiking, as nearly all of the rest of the over 6-mile hike was along residential roads. The only exception was a half-mile or so hike along a nearly impassable service road through a state reservation on the Princeton/Rutland town line.
Total Hike: 6.4 miles.
Midstate Trail to date: 35.9 miles.
Total summer to date: 43.0 miles.
