From Porirua follow the signs to Titahi Bay and continue until you reach the ramp at the right (north) end of Titahi Bay beach. Turn right here onto Richard St, then first left, then right. There is a parking area on the left at the start of Terrace Road.
These cliffs are relatively unstable. Avoid standing under them unnecessarily or scrambling over them. Sturdy footwear advisable.
The area of this GeoTrip is a short (5 minute) walk from the parking area. Walk down to the flat rocky area (wave-cut platform) below the road and follow a vague path to the right (north). There is a cave passage leading through to the next bay (mind your head!). This is the best place to see the erosion features locally.
