Dive Site: Pura Island Drop-off

About Pura Island Drop-off

Pura Island Drop-off, also known as Sharks Galore, is a dynamic dive site located off the coast of Pura Island in the Alor archipelago. This site is renowned for its diverse marine life and the potential for exciting encounters with larger pelagic species. The topography features impressive drop-offs and vibrant coral walls, characteristic of Alor's volcanic origins and nutrient-rich waters. While the site is a highlight for its lively currents and abundant fish action, it also showcases healthy hard and soft coral gardens, making it a visually stunning underwater landscape. The Alor region benefits from strong tidal exchanges between the Indian and Pacific Oceans, which transport nutrient-rich water through the Pantar Strait. This creates an exceptionally productive marine ecosystem that supports a wide array of species, from tiny macro critters to schooling fish and pelagic hunters. The site typically offers good visibility, especially during the dry season, enhancing the experience of exploring its intricate reef structures and observing marine interactions. Diving at Pura Island Drop-off usually involves drift diving, often starting with a negative entry due to the prevailing currents. These conditions, while challenging, contribute significantly to the site's rich biodiversity and make it a thrilling destination for experienced divers. The transition into adjacent sites like Clown Valley is sometimes possible, offering further exploration of Alor's unique underwater world. This dive site epitomizes the raw, untamed beauty of Alor's marine environment, making it a must-visit for those seeking an adventurous and rewarding dive.

Conditions & Currents

Pura Island Drop-off is well-known for its dynamic and sometimes strong currents, which are a defining characteristic of Alor's dive sites. These currents, influenced by significant tidal exchanges in the Pantar Strait, can be unpredictable in both strength and direction. Divers frequently perform negative entries to quickly descend and avoid being swept away from the desired dive path. While these currents demand experience and careful planning, they also bring nutrient-rich waters, attracting large schools of fish and pelagic species, enhancing the dive experience. Visibility typically remains good, often between 15-30 meters, though strong currents can sometimes stir up sediment. Divers should be proficient in drift diving techniques and be prepared for potential thermoclines.

Dive profile & how the dive runs

Diving at Pura Island Drop-off, often referred to as Sharks Galore, typically involves a negative entry from the boat due to the prevailing currents. Upon descent, you are immediately greeted by the steep drop-off and wall, which extends to considerable depths. The dive usually progresses as a drift, allowing you to observe the vibrant coral ecosystems and abundant fish life. You'll likely encounter grey reef sharks and white-tip sharks cruising in the blue, alongside impressive dog-toothed tuna. The current guides you along the wall, past schools of fusiliers, surgeonfish, and snappers. Depending on conditions and guide assessment, the dive may conclude in the adjacent Clown Valley, offering a different topography and marine encounters. Safety stops are performed in the calmer, shallower sections if available, or as a free-ocean ascent with an SMB.

Underwater photography

Pura Island Drop-off is an excellent site for wide-angle photography, capturing the dramatic wall, schooling fish, and pelagic encounters like sharks and tuna. A fisheye or wide-angle lens is ideal for showcasing the expansive reef and open water subjects. Due to potentially strong currents, stable buoyancy and quick reactions are essential to compose shots effectively. For larger animals, consider using natural light or powerful strobes to illuminate subjects in the blue. When photographing the prolific anthias and reef fish on the wall, careful positioning to avoid silhouetting against the open water is beneficial. Always prioritize maintaining a safe distance from marine life and avoiding contact with the delicate coral.

Getting there & logistics

Access to Alor, including Pura Island Drop-off, typically begins with international flights to Jakarta (CGK) or Bali (DPS). From there, domestic flights connect to Kupang (KOE) on Timor, followed by a smaller propeller plane to Alor's local airport, Mali (ARD) in Kalabahi. The journey can take a full day of travel. Most Alor diving is conducted from liveaboards or land-based resorts, often offering 7-10 day itineraries that combine various dive regions. Liveaboards frequently include Alor as part of routes covering Komodo, Flores, or the Banda Sea. Park fees are usually included in dive operator packages. Independent travel often requires coordination with local dive operators for boat transfers to dive sites.

Safety & environment

Diving in Alor, particularly at sites like Pura Island Drop-off, demands a high level of diver experience due to strong and unpredictable currents. All divers should be proficient in drift diving, have excellent buoyancy control, and carry an audible signaling device and an SMB. The nearest recompression chamber is in Denpasar, Bali, necessitating a lengthy and complex evacuation process, typically involving local boat, car, and air transport. Dive insurance, including emergency evacuation and recompression coverage, is therefore mandatory. Always follow your dive guide's instructions, especially regarding entry techniques and current management. Never dive beyond your training and comfort level.
