Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Initiated in 2000, BioWreck stands as a significant artificial reef project, evolving continuously since 2004 as the second largest Biorock project globally. Its primary purpose involves actively supporting coral growth through a continuous stream of low-voltage electricity, a process known to accelerate development by 3-5 times compared to natural rates.
Metal sculptures, intricately crafted into forms like mantas or cages, provide initial anchors in what were previously sandy areas. Here, coral polyps attach and thrive, transforming the seascape. Situated conveniently in front of some dive centers, accessing this site often means just a short walk from the beach.
Diving here typically ranges from 5 to 20 m (16 to 66 ft), making it suitable for a broad spectrum of diving proficiencies, from beginners to experienced divers exploring the developing ecosystem. These structures naturally attract various marine animals, offering essential shelter and rich foraging grounds, creating a dynamic environment for observation.
Beyond its appeal as a dive destination, BioWreck functions as a crucial research and restoration hub, demonstrating a distinctive, man-made topography that supports a flourishing underwater habitat. Divers will discover an evolving landscape beneath the surface.

Optimal conditions expected
Current conditions near BioWreck show 25° air, 29° sea temperature, 0.3 m waves, and 15 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
Optimal visibility at BioWreck typically aligns with Indonesia's dry season, stretching from March through November, when 'Excellent' dive scores are consistently reported. During these months, rainfall significantly decreases, with values as low as 0.81 mm in August, contributing to clearer underwater conditions. Air temperatures remain warm and comfortable, averaging between 26-28°C (79-82°F). While specific water temperature data for BioWreck isn't consistently reported, the surrounding Indonesian waters typically maintain a comfortable tropical range. The slightly increased wave heights and wind speeds observed in July, August, and September (around 0.4 m waves, 15-16 km/h winds) are generally not strong enough to significantly impede visibility within the protected Biorock area, as currents tend to flow through, rather than against, the structures. The period from January to February sees slightly higher rainfall and 'Good' dive scores, indicating generally favorable but potentially less pristine conditions.

Dive Experience & Conditions
Navigating BioWreck offers a straightforward and rewarding experience. Divers encounter a series of Biorock structures specifically designed for easy passage; some are even shaped like familiar marine animals, enhancing underwater exploration. Accommodating a wide spectrum of diving proficiencies, from Discover Scuba Diving participants to advanced divers, a recommended depth range of 5 to 20 m (16 to 66 ft) is observed. Currents typically flow through the artificial structures, rather than pushing directly against them. These flow patterns generally contribute to a manageable environment. Such conditions allow for relaxed exploration of the vibrant coral growth and the abundant life taking refuge within the metal frames. Close proximity to shore and generally calm conditions make the site suitable for both day and night dives, revealing different perspectives on resident marine populations and coral health.
Dive Difficulty & Safety Guidelines
Navigating BioWreck requires adherence to standard safety practices, ensuring a responsible and enjoyable dive. While specific hazards are not consistently reported for this site, general caution is advised when interacting with any artificial reef structures to avoid accidental damage or injury. Divers should maintain neutral buoyancy to prevent contact with the delicate coral polyps actively growing on the Biorocks. Observing the 'max 4 divers per guide' guideline ensures personalized attention and supervision, particularly beneficial for less experienced divers. All participants, including those undertaking a Discover Scuba Diving program, are required to complete a self-assessment medical survey prior to diving. Always attend your pre-dive briefing to understand current conditions and specific site protocols.
