What Makes Red Pillar Special

Red Pillar is named after the red channel marker that stands above the water in the middle of the reef and guides the ferries in and out of Havelock. The pillars that hold up the marker are now covered in coral.

It is a shallow reef just off Peel Island, about 1 km north of Havelock, with the crest at 2.5 to 3 metres and the bottom at around 12 metres. That makes it a beginner site: first-timers and non-swimmers dive it with a one-to-one instructor, and certified divers use it as an easy fun dive.

The Dive Experience: The Pillar Awaits

After 5 to 10 minutes by boat, you descend onto the reef crest close to the red marker. The top is a hard coral garden with clownfish in the anemones, and schools of snappers and fusiliers move over it.

Further down, at 8 to 12 metres, you reach bathtub-sized barrel sponges and a sunken scooter and bicycle that are now covered in coral. Look on the sand for stingrays, and let your instructor point out the well-camouflaged crocodile fish and scorpionfish.

Red Pillar is a fun one to show first-timers. You start in shallow water by the marker, and there is always something odd to find further down, like the old scooter and bicycle or the huge barrel sponges. The channel can have some current, so your instructor keeps you close and sets the pace.
