Good trail. Parking is at South Acton Fire Station. Various trails marked by painted patches on trees. The yellow trail is the biggest loop, taking you along the perimeter of the whole area.

Very dog friendly and off leash is allowed. Not a place to go if you don't want to be approached by random by other dogs. Also, the field behind the fire station is used as a dog park almost 24/7, but especially on Sunday morning.

Regarding the dog park, try not to bring aggressive or protective dogs on Sundays. It may be overwhelming. However people are generally accepting if you're trying to socialize your dog and will usually let them "work things out." Still, be sure to be nearby in case things escalate.

3 Stars for a solid, easy hike, accurate trail maps and dog friendlyness, but no great views or scenery.
