Dogs are welcome to join their owners at Cashman Park. The park goes off in two directions. Jump on the paved path toward the Merrimack River and turn right to the off-leash dog park. This area is not strictly a dog park in the traditional sense, but more a shared area for dogs and their owners to use, too. The Clipper City Rail Trail can also be accessed from the park. There's a boat launch and small fishing pier where visitors can stroll and take in the view. The park can be accessed 7:30am to 9:00am and 4:00pm to 7:00pm.
