There aren't too many "mountains" in the Boston area, so having the word attached to a recreation area, even if it's not accurate, is rather intriguing. And after finally hiking through the Wilson Mountain Reservation in Dedham last weekend, I can say that no, Wilson Mountain is not really a mountain, but it is a peaceful, scenic spot with deep woods, bubbling brooks (see photo), and a surprisingly steep hill with decent views at the top.
We started our hike from the small parking lot (room for 10 cars or so) along Route 135 just east of Route 128. The green dot trail started out as what looked like a logging road, but it quickly became narrower and steeper once the red dot loop veered off to the right. As we skirted the top of the hill, some limited views of the Blue Hills could be seen to the east, but then we quickly lost the views as we descended into a deeply woooded are with many streams. A little more than halfway through the green loop, we took a side trail up to the red dot trail, where we took a right and were soon dropping steeply from the hill, on the part of the trail where the red and green dot were one and the same. Then the red dot trail left the green dot and passed through a beautiful pine forest (see photo) before starting a rather treacherous scamper up toward the summit of Wilson Mountain.
Once we reached the summit, we took a breather, enjoying the fine views of the Boston skyline and the unusual rock formations at the top (see photo). Then we went back along the side trail down to the green dot trail where we continued on from where we had left off earlier. This part of the green dot was mostly flat and eventually went parallel to Route 135, but it was still quite nice, with several streams and some wetlands along the way. The trail took us back to the parking lot, but we continued on to another trail that skirted the eastern boundary of the reservation and led to a large meadow. From there, we turned around and headed back to the lot.
You can do about 4 miles or so in the Wilson Mountain Reservation if you hit all of the trails within the area. Figure on about 2 hours for the hike, plus any breaks you might take.
