This historic district has so many stories to tell, starting with the Lenni Lenape Indians that originally occupied this area. Many of their artifacts have been found in this area, along with signs of early European settlers and 18th-century agriculture.

This mostly unpaved trail makes a 5-mile (8Β km) loop on the north side of Mercer Lake. Keep an eye and ear out for mountain bikers, who also use the same trail.

Your run takes you right past the Boathouse at Mercer Lake, which was recently renovated with 19-foot vaulted ceilings inside, tasteful stonework outside, and a long dock jutting into the lake. This is a popular venue for weddings.

Mercer Lake, also called Lake Mercer, is a man-made lake 365 acres in size in Mercer County Park. Keep an eye out for rowers, as this lake is home to one of a few of the US Olympic Rowing Team's training centers. Though this lake appears quite clear, it has historically faced pollution issues from runoff and nearby golf course waste.
