Split Rock (), a large dome-shaped granite boulder measuring approximately from north to south and from east to west, is located at the intersection of the New England Thruway and Hutchinson River Parkway, on a triangular parcel of land formed by these roads and a ramp that leads from the northbound Parkway to the northbound Thruway. The only public access to the rock is by a pedestrian trail that begins on Eastchester Place, outside the park. The Bridle Trail passes close to the rock, but is separated from the rock by the parkway's exit ramp. Another park trail, called the Split Rock Trail, leads from the Bartow Circle to the rock.
