The Southern New England Trunkline Trail is a National Scenic Recreational Trail that runs from Franklin Massachusetts 86 Miles to Willimantic Connecticut. The Massachusetts portion is a linier park managed by the Department of Conservation and Recrretion.

This write-up concerms the Massachusetts portion starting in Franklin and ending near the Connecticut line in the Douglas State Forest.

Few people will ever ride the entire 22 miles. But, many people ride parts of it, using it to connect good riding areas.

The trail itself is straight, very flat but has many whoop-de-dos caused by off road vehicle use. It's very scenic and beloved by area equestrians. 

On the eastern end you have the trail dense Franklin State Forest.

On the western end in the Douglas State Forest there's an alternate staring area at 108 Wallum Lake Road where the SNETT crosses the road.

 From this point if you continue west you'll hit the Connecticut state line. Of particular interest is the Tri State Marker. A stone monolith that marks the intersection of RI, CT and MA. Ride around it and you'll hit three states in a second or two.  Where else can you do that?
