The southern section began at Lusty Glaze, where the site of the incline down the cliffs is still clearly visible. It headed east, before sweeping to the south and then the north around Porth Veor and Higher Porth, now both part of Newquay. From Porth, it turned to the east, following the contour. Its course is marked by several field boundaries as it approaches St Columb Minor. An original bridge still carries the footpath from St Columb Minor to Penrose over the course of the canal. It turned to the south-east to reach Priory Road, and then continued to the east towards Rialton Mill. Near the junction of Priory Road and the A3059 Rialton Road, it turned to the south, to end where the minor road to Rialton Barton leaves the A3059.
