Caribbean Netherlands dive sites

Klein Bonaire is a short boat ride from Kralendijk, Bonaire's main town, taking approximately ten to fifteen minutes depending on the departure point. Most dive operators on Bonaire include Klein Bonaire sites in their regular boat dive schedules, typically offering two-tank morning trips that visit one site on the main island and one on Klein Bonaire. Water taxis also run to No Name Beach on Klein Bonaire's eastern shore, allowing snorkellers to explore independently. The island is uninhabited and has no facilities, so divers should bring water and sun protection. Landing on the beach is permitted during daylight hours, but overnight camping is not allowed.

Klein Bonaire's reef benefits from the complete absence of coastal development. With no buildings, roads, runoff, or artificial lighting on the island, the reef receives none of the stressors that affect even well-managed coastlines. The result is visibly healthier coral coverage, greater species diversity, and more natural fish behaviour compared to sites along Bonaire's developed western shore. The reef structure is continuous and uninterrupted, with no gaps caused by boat channels, piers, or other infrastructure. Coral bleaching events have affected Klein Bonaire, but recovery has been faster here than on the main island, likely due to the absence of compounding local stressors. The reef represents a near-pristine Caribbean benchmark.

Unlike Bonaire's famous shore diving along the main island's western coast, Klein Bonaire is accessed exclusively by boat as there is no bridge or ferry infrastructure. However, once at the island, the reef structure is similar to the main island's sites: a shallow terrace leads to a drop-off that begins between eight and twelve metres before descending as a wall or steep slope to thirty metres and beyond. The shallow terrace makes excellent snorkelling territory, and many boats drop snorkellers at No Name Beach while divers explore the deeper reef. The boat-based access means that currents and conditions are assessed by the captain, adding a layer of safety management that shore diving does not provide.

HMS Proselyte was a thirty-two-gun fifth-rate frigate of the Royal Navy that struck an uncharted reef off the south coast of St. Maarten on 4 September 1801 and sank. The ship was originally a Dutch vessel, the Jason, captured by the British and renamed. No lives were lost in the sinking, as the crew was able to evacuate before the ship settled on the reef. Over two centuries, the wooden hull has mostly disintegrated, but the heavier elements including iron cannon, anchors, copper sheathing fragments, and stone ballast remain on the seabed, now incorporated into the natural reef structure. The wreck site is protected under Sint Maarten maritime heritage regulations, and removing any artefacts is illegal.

Proselyte Reef is suitable for divers of all levels, from recently certified Open Water divers to experienced wreck specialists. The maximum depth is around eighteen metres, and the site is typically calm with minimal current. The wreck elements are scattered across a wide area of reef rather than concentrated in a single deep structure, so there are no penetration hazards. Beginners can enjoy the shallow coral sections and fish life, while more experienced divers can spend time identifying historical artefacts among the coral. Several dive operators in Philipsburg and Simpson Bay offer regular boat trips to the site, with the journey taking approximately fifteen minutes.
