Gate 16 at Quabbin Reservoir in Shutesbury, Massachusetts is an easy 1.2 mile out-and-back hike down to the northwestern shores of Quabbin.
The trail starts off at a large parking lot across the street from Prescott Rd, along Route-202 and cuts through the woods before hitting a service road. When you hit the service road, take a right-hand turn and continue hiking downhill until you reach the water. Around mile X, you'll pass another trail/service road, but stay left to continue heading downhill.
At the end of the trail is a popular fishing spot - which requires a state fishing license.
The hike back uphill is fairly gradual, hence the easy difficulty.
Note: The ESRI and OpenStreetMap tiles show the trail leading into the water; however, the map tiles are wrong. Google Maps has the proper topo layout for the tail end of the trail.
Dogs are not allowed on this trail or at Quabbin.
