Marlborough Dog Park

Marlborough Dog Park, located at the back of Ghiloni Park, is a large and comfortable space for dogs to enjoy. The park features mulch ground cover, several logs and rocks as natural obstacles, and some shaded areas from a few trees. While there is no water fountain onsite, the park provides poop bags and trash bins for convenience. Note that the ground may have some broken sticks. The park has parking available nearby but does not mention paved paths, lighting, or other specific amenities.

Very large, comfortable park. My dog has a lot of fun, but they should throw rocks or sand on the floor. It has many broken sticks and my dog buried one, but I was able to get it out.

Revised — the park is now officially open!
Mulch ground cover, a few trees providing some shade. No water. Poop bags and trash. Rocks and several logs left as obstacles.
This is located at the back of Ghiloni Park, taking the roadway out the back of the parking lot and toward the town forest trails.

Not open as of 6/8/25 😞
