Head for the car park at the end of Denby Road, near Hawera. Follow the obvious track down to the beach. The outcrop on the left just before the beach is a good place to access sediments and fossils before descending to the beach itself.
These sea cliffs can be very dangerous due to the frequency of rockfalls, expecially during or after wet weather. It is highly recommended that you keep away from the vertical cliffs as much as possible. The boulders on the beach are derived directly from the cliffs, so if you time your visit at low tide, you can search at a safe distance for the good fossil material.
From the car park descend the track for about 5 minutes to the beach. The cliff that you first see on the left (before getting to the beach) allows good access to the boundary layer (unconformity) between the two main rock units.
