Pet-Friendly National/State/Local Park in Andover, Massachusetts

Description - Very small. Quaint and beautiful. This park has been around since 1902. It is a fun picnic/swimming/amusement park with four roller coasters and a variety of other amusement park-esque things. There's a picnic area, so you can bring a backpack in with some food and, if you bring a water dish, there are plenty of water fountains and grassy areas. Of course, you'll need to clean up after your pet, but that's a given. So, the kids can ride the rides and the dog can come along and have a bite of their hot dogs.
