Along the Zuytdorp cliffs are massive and tiny blow-holes, the most known and
well signed are
Thunder bay blow-holes and
False Entrance blow-holes.
Thunder Bay really looks out of this world with a massive reef shelf which gets covered by water from the waves. The blow holes are located to the north of the bay and are very big; take good care as there are some smaller holes around that are not always easy to see until you're only a few meters away, some are still big enough for a person to fall in.
