The Cady Lane Trail in Ware, MA, is an easy 0.6 mile loop hike that leads to some nice fishing spots along the Swift River.
This short trail leads from parking on River road over to the Swift River and back; however, it does appear to continue down the river for a ways, but I never ventured further.
You'll likely see a lot of kayakers, and canoers here on weekends.
For parking, head to the coordinates or use the address provided. If using the address for directions, the lot is next to the address listed and is set back about 50 feet from the road.
