The victim, a 65-year-old man from Devon, was sitting on a park bench when he was hit by a 45-foot long limb on Thursday afternoon.
He was pronounced dead at Bryn Mawr Hospital shortly after 3:00 p.m.
The man's name has not been released because his family has not yet been notified.
The trail is maintained by the township and, officials said, several overhanging branches were pruned in early spring.
Those officials added that there had been no previous serious incidents or accidents on the trail.
