The Klein Bonaire islet, which sits within the rough crescent formed by the main island, is 6 square kilometres (1,483 acres) and extremely flat, rising no more than two meters above the sea.

Klein Bonaire is permanently home to green (Chelonia mydas) and hawksbill sea turtles (Eretmochelys imbricata).

[4] Klein Bonaire has been identified by BirdLife International as an Important Bird Area (IBA) because it supports populations of threatened or restricted-range bird species, including bare-eyed pigeons, least terns and Caribbean elaenias.

The primary attraction for visitors is scuba diving and snorkeling the pristine coral reef surrounding the islet.

Numbered yellow painted rocks near the open shelter show where divers can cross low points on the reef, which is very close to the beach.
