Norfolk County Highpoint Trip Report
 
Great Blue Hill
Date: September 7, 2005 
Authors: John and Kathy Mitchler 
This county is great for families and kids. The road shown on the topo is paved 
but restricted to official vehicles and is gated.  I recommend you park next to 
it in the huge paved lot near the museum's restroom building. 
At the center edge of this lot, find a gravel hiking trail (old road shown on 
the topo) and take it uphill to meet the paved road.  Follow the paved road to 
the summit. A gravel road near the summit leaves the paved road to the left and 
goes to a wonderful stone tower with a view of Boston.  The highpoint has two 
parking lots, two radio tower facilities, and one castle-like tower that is an 
observatory. The highest bedrock appeared to be inside the iron fence.  
This observatory is the oldest continuously operating observatory in the USA 
(February 1, 1885) and is open to members (617-696-0562).  Apparently, Great 
Blue Hill is the tallest point along the Atlantic coast south of Maine.  
There are 22 hills in the Blue Hills chain. 
We took exit 2 off I-93, just a couple miles east of the junction of I-93 and I-95, 
and drove north on MA 138 for a half mile, passing the ski area parking lot 
and Blue Hills Trailside Museum to reach the trailhead parking lot on the right.  
If you see Green Street on your left and Canton Avenue on your left, you've gone too far. 
We left the area by going north on MA 138 (Blue Hills Avenue) to Boston.
