Klein Bonaire is an uninhabited island whose dive sites wrap around its perimeter, offering a consistent mix of shallow coral terraces, sloping reefs, walls and drop-offs. The sheltered western side suits beginners, with sites like Knife, Munk's Haven and Hands Off delivering gradual reef slopes before the bottom falls away. The northern tip and southern coast, including Carl's Hill and Captain Don's Reef, present steeper walls for intermediate divers. Marine life is rich throughout: French Angelfish, Fairy Basslet and Black Durgeon are observed across virtually every site, while Spotted Moray and Indian Lionfish add character in the reef crevices. All access is by boat.

A good number of Klein Bonaire's sites are rated for beginners, particularly those on the sheltered western side such as Knife, Munk's Haven and Hands Off, where shallow coral terraces lead gradually into deeper water. Intermediate-rated sites such as Captain Don's Reef, Carl's Hill and Ebo's Reef involve steeper walls and drop-offs and are better suited to divers with more experience managing depth and buoyancy.
Almost all dive sites at Klein Bonaire are reached by boat, as the island itself is uninhabited and has no shore infrastructure for most locations. Leonora's Reef is a notable exception, listed as a shore-entry option alongside boat access. Most sites use mooring buoys, which helps protect the reef and keeps anchoring to a minimum.
The western and south-western sides, including sites like Knife, Bonaventura and Hands Off, tend to be sheltered and are home to many of the more approachable reef slopes. The north-eastern tip at Carl's Hill and the southern coast at Captain Don's Reef offer steeper walls and more pronounced drop-offs. Keepsake, with its deep wall beginning well below the surface, is suited to those comfortable at greater depth.
