About Jepun (Ferry Channel)
Jepun (Ferry Channel) is a dynamic dive site located off Bali's east coast, renowned for its strong currents and the exciting drift diving opportunities they create. This site forms part of a crucial marine corridor where nutrient-dense waters fuel a rich ecosystem, supporting a diverse array of fish and invertebrates. The underwater topography primarily consists of sloping reefs and dramatic walls, adorned with healthy hard and soft corals that thrive in the consistent water movement. Divers here can expect to encounter large schools of pelagic fish, various reef sharks, and an impressive collection of macro life tucked into crevices and coral formations. While the site offers year-round diving, the dry season from April to November generally provides the best visibility and most stable conditions, though currents remain a defining feature. The unique interaction of currents, topography, and marine biodiversity makes Jepun a thrilling experience for divers seeking an active and visually rewarding underwater adventure. Access to Jepun is typically via local dive boats, often traditional jukungs, departing from nearby coastal towns. The experience is characterized by negative entries to quickly descend below the surface currents, followed by a guided drift along the reef. Divers must maintain excellent buoyancy control and be comfortable with the sensation of being carried by the water, making it a site best suited for intermediate to advanced divers.
Highlights
Season calendar
Apr – Oct (Apr–Nov)
The dry season brings calm seas, 25–30m+ visibility, and strong currents that attract mantas, sharks, and pelagics to Komodo. Alor offers pristine reef diving with 20–40m visibility. Bali's Nusa Penida delivers Mola Mola encounters from July to October. Water temperatures range from 24–28°C — a 3mm or 5mm wetsuit is recommended.
Nov – Mar (Oct–Apr)
Raja Ampat peaks during the wet season with calmer seas, plankton-rich waters attracting manta rays, and excellent biodiversity. Water is a warm 28–30°C with 15–25m visibility. The Banda Sea opens its rare expedition window from September to December, with hammerhead sharks and pristine seamounts. Lembeh Strait offers world-class muck diving year-round.

Conditions & Currents
Jepun (Ferry Channel) is defined by its strong and often unpredictable currents, necessitating advanced drift diving techniques. Divers frequently perform negative entries to quickly descend beneath the surface chop and into the calmer water column, staying close to the reef to mitigate the strongest flows. These currents, while challenging, are responsible for the site's rich biodiversity, bringing in pelagic species and delivering nutrients to the corals. Visibility can range from 10m during the rainy season to an impressive 40m in the dry season, though strong currents can sometimes stir up sediment. While thermoclines are less common here compared to sites like Crystal Bay, water temperatures can vary, especially with depth. Divers must be proficient in buoyancy control, air consumption management in dynamic conditions, and be comfortable with safety stops in open water, as surfacin

commonDive profile & how the dive runs
Your dive at Jepun (Ferry Channel) begins with a negative entry from a traditional jukung, ensuring a swift descent below the strong surface currents. Upon reaching approximately 5-10 meters, you'll find the primary reef slope, which gradually deepens to over 30 meters. The dive typically proceeds as a drift along the reef, with the current guiding you past vibrant coral gardens and dramatic wall sections. Your guide will lead the way, maintaining a course that optimizes marine life encounters while managing the current. Expect to maintain a depth between 15-25 meters for most of the dive, adjusting as needed to explore specific features or avoid stronger currents at certain points. The turn point is determined by air consumption and current conditions, with the safety stop usually conducted in the blue, deploying a surface marker buoy (SMB) for the boat to track your ascent and pickup.
Underwater photography
Jepun's dynamic conditions offer excellent opportunities for both wide-angle and macro photography, though the strong currents require careful planning. For wide-angle shots, consider capturing the expansive coral slopes and schools of pelagic fish. A fast shutter speed and good strobe placement are crucial to freeze action and bring out vibrant colors in moving subjects. For macro enthusiasts, patience and excellent buoyancy are essential to photograph smaller creatures tucked into coral crevices, as the drift will constantly move you. A focus light will aid in identification and sharp focus in shaded areas. Always be mindful of your fin kicks to avoid disturbing the reef or stirring up sediment, which can quickly ruin a shot and harm the environment.

Ensure your dive operator is reputable and experienced with strong current dives.
Safety & environment
Diving Jepun (Ferry Channel) requires a strong emphasis on safety due to its prevalent strong currents. It is imperative that divers are Advanced Open Water certified and have prior experience with drift diving. Always dive with a reputable operator, and ensure you are comfortable with negative entries and deploying a Surface Marker Buoy (SMB) for safety stops and surface pickup. The nearest recompression chamber is in Denpasar, approximately 1.5 to 2 hours away from Padang Bai. Evacuation in a dive emergency would involve immediate transport by boat to shore, followed by road transfer to the chamber.
