Ball Fields. This is NOT AN OFFICIAL DOG PARK, it’s baseball fields and tennis courts. But there is a good-sized fenced in ball field which is open to pets as long as you are willing to scoop the poop! Location: West Road (off King St). Directions: Exit 17 off 1-93 onto Route 3 North. Head into the Boscawen town center (King Street) and West Rd is on your right just before Cumberland Farms. The park is at the end of the road, which curves to the right.
