Klein Bonaire in the context of "Bonaire National Marine Park"

The Leeward Antilles (Dutch: Benedenwindse Eilanden; Spanish: islas de Sotavento) are a chain of islands in the Caribbean, specifically part of the southerly islands of the Lesser Antilles (and, in turn, the Antilles and the West Indies) along the southeastern fringe of the Caribbean Sea, just north of the Venezuelan coast of the South American mainland. The Leeward Antilles, while among the Lesser Antilles, are not to be confused with the Leeward Islands (also of the Lesser Antilles) to the northeast.

Largely lacking in volcanic activity, the Leeward Antilles island arc occurs along the deformed southern edge of the Caribbean Plate and was formed by the plate's subduction under the South American Plate. Recent studies indicate that the Leeward Antilles are accreting to South America.

The Caribbean Netherlands (Dutch: Caribisch Nederland, pronounced [kaˈribis ˈneːdərlɑnt] ) is a geographic region of the Netherlands located outside of Europe, in the Caribbean, consisting of three special municipalities. These are the islands of Bonaire, Sint Eustatius, and Saba, as they are also known in legislation, or the BES islands for short. The islands are officially classified as public bodies in the Netherlands and as overseas territories of the European Union; as such, European Union law does not automatically apply to them.

Bonaire (including the islet of Klein Bonaire) is one of the Leeward Antilles and is located close to the coast of Venezuela. Sint Eustatius and Saba are in the main Lesser Antilles group and are located south of Sint Maarten and northwest of Saint Kitts and Nevis. The Caribbean Netherlands, a term distinct from the comprehensive Dutch Caribbean, has a population of 31,980.

Bonaire is a Caribbean island in the Leeward Antilles, and is a special municipality (officially "public body") of the Netherlands. Its capital is the port of Kralendijk, on the west (leeward) coast of the island. Aruba, Bonaire and Curaçao form the ABC islands, 80 km (50 miles) off the coast of Venezuela. The islands have an arid climate that attracts visitors seeking warm, sunny weather all year round, and they lie outside the Main Development Region for tropical cyclones. Bonaire is a popular snorkeling and scuba diving destination because of its multiple shore diving sites, shipwrecks and easy access to the island's fringing reefs.

As of 1 January 2025, the island's population total 26,552 permanent residents, an increase of 10,011 since 2012. The island's total land area is 288 square kilometres (111 sq mi); it is 38.6 kilometres (24.0 mi) long from north to south, and ranges from 5–8 km (3–5 mi) wide from east to west. A short 800 metres (0.50 mi) west of Bonaire across the sea is the uninhabited islet of Klein Bonaire with a total land area of 6 km (2.3 sq mi). Klein Bonaire has low-growing vegetation including cactus, with sparse palm trees near the water and is bordered by white sandy beaches and a fringing reef. The reefs, beaches and on-island reserves located on both Bonaire and Klein Bonaire are under the protection of the Bonaire National Marine Park, and managed by STINAPA Bonaire.

Kralendijk (Dutch pronunciation: [ˈkraːlə(n)dɛik]) is the capital and main port of the island of Bonaire in the Caribbean Netherlands. The language spoken in the town is Papiamentu, but Dutch and English are widely used. As of 2017, the town had a population of 10,620. In Papiamentu, the town is often called Playa or "beach".

Off the coast of Kralendijk lies the uninhabited island of Klein Bonaire, noted for diving and snorkeling activities. This small island can be reached by water taxi, or, for divers, by practically all of the local dive operators.
