Dogs are welcome to join their owners at Hopkinton State Park. Home to 1,500 acres of forests full of hiking trails to explore with your pooch. There are ten miles of pet-friendly marked trails dotted around the park in total, some of them weave around beaches, stocked fishing sites, and picnic areas. You can bring Fido with you to enjoy the area, as long as they are on a leash under six feet and owners clean up any mess that they leave behind. Hopkinton State Park is open every day of the week from sunrise to sunset.
