I have read about a 57 mile drive that circles the Reservoir. It is called the Central Hills Loop. I am unable to find a map that details the roads to take. I checked out the website for the Quabbin itself and did not see the drive mentioned, just various hikes.
The Quabbin Reservoir in central Massachusetts is a beautiful spot for fall foliage, and the so-called “Central Hills Loop” is a scenic drive that roughly circles the reservoir. While it is not officially published by the Massachusetts Department of Conservation and Recreation, enthusiasts have pieced together a recommended route using local roads and state highways.
The loop is approximately 57 miles and combines state routes with smaller back roads that pass through forested areas, open hills, and several historic towns near the reservoir. You can complete the loop in about 2–3 hours without stops, though it’s ideal to take more time for photo opportunities and short walks.
A general outline of the drive is as follows:
Tips for the drive:
Although an official map for the Central Hills Loop is not published, local blogs and foliage guides often provide GPS tracks or printable routes. Using Google Maps or a GPS app, you can follow the above route and modify as desired to include more scenic stops.
