This landscape is typical for the Niuean coastline. You can see the general shape of Niue here - the island is roughly made of two plateaus. The central plateau, rising about 60m above the ocean (the highest point of Niue is a small hill in the north, reaching 69m above sea level), is ringed by a narrow plateau a bit lower. Steep coral cliffs are between the plateaus and the ocean. Plenty of jagged razer-sharp coral rocks jut out all around the island, in what I proclaim to be the worst place for a baby to learn to walk. You can get cut up pretty badly if you  fall anywhere on the island!
