Hartlepool train station is a ten minute walk from the ground. Leave the station and go straight up a short approach road. At the end of the approach, turn right and head up Church Street towards the large church. At the end of this road is a bridge and junction with the A689. Go straight across the junction and the ground is in front of you on the left hand side of the road.
Ground: Top left, catch the arrow; Station: Bottom right, the blue blob.
