Dive Site: Over the Wall

About Over the Wall

"Over the Wall" on Andros Island presents a unique and dramatic diving experience at the edge of the Tongue of the Ocean, an immense oceanic trench reaching depths of 1,820 meters. This site is characterized by an abrupt vertical drop, where the vibrant coral reef gives way to the deep blue abyss. Divers typically explore the upper reaches of this wall, navigating along its precipice. The location's oceanic exposure contributes to exceptional visibility, frequently offering clear views into the vast depths below. While day dives here offer expansive wall exploration, the site truly transforms after sunset. "Over the Wall" is particularly celebrated for its night dives, during which divers can witness spectacular natural light shows. Turning off artificial lights reveals a world illuminated by bioluminescent dinoflagellates, plankton that create shimmering, ethereal glows in the water. This phenomenon makes it a compelling destination for those seeking unique underwater photography opportunities and an unforgettable nocturnal experience. Due to its depth potential and the nature of wall diving, this site is best suited for experienced divers comfortable with advanced profiles and buoyancy control. It offers an encounter with the raw, untamed beauty of the deep ocean's edge.

Conditions & Currents

Currents at "Over the Wall" are typically mild, but due to its location on a vast oceanic wall, occasional moderate currents can be encountered, necessitating good buoyancy control and dive planning. Divers descend onto the reef plateau and follow the wall, which plunges past recreational limits, requiring careful depth management. The exceptional visibility, often ranging from 30 to 45 meters, provides clear views of the wall and any approaching marine life, though deep profiles demand attention to gas consumption. Entry and exit are usually boat-based, and careful monitoring of current conditions by the dive operator is essential to ensure diver safety along the vertical drop-off.

Dive profile & how the dive runs

Dives at "Over the Wall" typically begin with a boat drop directly onto the reef plateau, which sits at approximately 18-20 meters. From here, divers navigate towards the wall, where the seabed abruptly drops into the Tongue of the Ocean. The dive profile involves exploring along the edge of this dramatic vertical face, with the vast abyss stretching downwards. Many recreational divers will stay within the 20-30 meter range, admiring the deep-water coral formations and seeking out marine life that patrols the wall. For night dives, the approach is similar, with the highlight being the controlled switching off of dive lights at around 20 meters to fully appreciate the natural bioluminescence. The turn point is determined by gas consumption and no-decompression limits, with the ascent along the wall to a safety stop on the reef plateau before a boat pick-up.

Underwater photography

Capturing the essence of "Over the Wall" requires a versatile approach. For wide-angle photography during the day, a fisheye lens is ideal to convey the sheer scale of the wall and the deep blue expanse. Strobes are essential to bring out the vibrant colors of the coral and sponge formations on the wall's edge. During night dives, the focus shifts entirely to capturing bioluminescence. This often means experimenting with long exposures, high ISO settings, and minimal artificial light, if any, to truly showcase the natural glow of the dinoflagellates. Buoyancy control is paramount, especially when navigating close to the wall's delicate corals or drifting in the dark, to avoid disturbing the environment and maintain stable shots.
