Deer run is a shorter trail that runs through the middle of the park. It cuts off the southwest corner of the Framingham side, which makes a good shortcut to and from the Marlborough side if parked at Millwood Street. It's often muddy in the spring and even early summer however.
The trail leaves Rocky Rd to the east, then turns south, descending towards the Framingham side's low lying center. It intersects with Fox Hunt
and Lady Slipper
Then it crosses Moore Rd. less than 1 km from the Millwood St. lot. The trail continues south from here and meets up with Pinecone
and Coco Ridge
