Dive Site: Saleh Bay

About Saleh Bay

Saleh Bay is a unique marine ecosystem located on Sumbawa, an island situated between Bali and Komodo in Indonesia. Geographically distinct, it's a large, central bay cutting deep into the island from the north coast, primarily featuring depths between 30 to 50 meters, with a narrow opening to the Flores Sea on its eastern side. This sheltered environment, surrounded by lush hills and dotted with fishing villages, creates ideal conditions for diverse marine life. The bay is globally recognized for its reliable whale shark aggregations, which gather around traditional fishing platforms (bagan) that attract small fish and plankton. Beyond these gentle giants, the waters host vibrant coral gardens, underwater caves, and dynamic wall dives. Divers can explore extensive reef systems teeming with colorful fish, while muck diving areas reveal an abundance of macro life. The nutrient-rich environment supports a wide array of species, including manta rays, various reef sharks, and schools of barracuda. Macro enthusiasts will discover nudibranchs, pipefish, seahorses, and frogfish among the sandy bottoms and seagrass beds. The sheltered nature of the bay also contributes to generally calm conditions and clear visibility, making it suitable for both novice and experienced divers. Diving in Saleh Bay offers an authentic, off-the-beaten-path adventure, often with fewer crowds compared to more established Indonesian dive sites. Liveaboard itineraries typically combine whale shark encounters with exploration of these pristine reefs, providing a comprehensive and rewarding experience away from mainstream tourist spots. The focus is on respectful wildlife interaction and preserving the untouched beauty of the area.

Conditions & Currents

Saleh Bay generally offers calm, sheltered waters, making it an accessible dive destination. However, specific sites, especially wall dives and those exposed to the bay's opening, can experience varying current strengths. Whale shark encounters typically involve surface-based interactions around fishing platforms where food sources accumulate, often in calmer conditions. Visibility in the bay is generally excellent due to the stable conditions, but like any nutrient-rich environment, plankton blooms can occasionally reduce it. Water temperatures remain comfortably warm, ranging from 26°C to 29°C. Divers should be prepared for early morning departures for whale shark encounters, which are primarily snorkelling interactions. The overall dive experience is often suitable for a range of skill levels, though awareness of currents at certain dive sites is always prudent.

Dive profile & how the dive runs

Dives in Saleh Bay typically begin with a tender entry from a liveaboard, with specific whale shark encounters often involving surface-based observation. For reef dives, you'll generally descend onto vibrant coral gardens or along walls, such as those at Tanjung Menangis or Angel Reef. Depth progression varies, but many reef sections are rich in marine life between 10 and 25 meters, allowing for extended bottom times. Muck diving sites focus on shallower sandy bottoms, exploring for macro creatures. Turn points are dictated by air consumption and no-decompression limits, with guides leading efficient routes to maximize sightings. Safety stops are usually conducted in the sheltered shallows, often around the 5-meter mark, where colourful reef fish provide a pleasant final observation opportunity. Dive durations typically range from 50 to 60 minutes.

Underwater photography

Saleh Bay offers diverse photographic opportunities, from wide-angle for whale sharks and expansive coral formations to macro for its rich muck sites. For whale shark encounters, a wide-angle lens (e.g., 10-24mm) is essential to capture the full size of the animals. Natural light is often sufficient during morning encounters, but strobes can enhance colours on reef dives. For macro photography, a dedicated macro lens (e.g., 60mm or 100mm) is recommended, often paired with snoots or dual strobes to highlight tiny subjects like nudibranchs and frogfish. Excellent buoyancy control is paramount to avoid disturbing delicate corals and bottom dwellers. When photographing whale sharks, maintain a respectful distance of at least three meters and avoid using flash to prevent startling them. Patience and a keen eye are key to capturing the bay's unique biodiversity.

Getting there & logistics

Access to Saleh Bay is predominantly via liveaboard, which often integrate it into extended Komodo itineraries from Labuan Bajo. Alternatively, you can fly to Lombok (LOP) from Bali (DPS), then take a domestic flight to Sumbawa Besar or a ferry and car transfer to reach the bay. The Whale Shark Saleh Bay team can assist with transfers and arrangements within Sumbawa. Trip lengths vary, but liveaboards combining Komodo and Saleh Bay typically run for 9-10 nights, including around 23 dives. Marine park fees are generally modest compared to other Indonesian parks. These routes are carefully planned to align with the best seasonal conditions for both whale shark encounters and Komodo's iconic dive sites, making for a comprehensive Indonesian dive adventure.

Safety & environment

While Saleh Bay offers generally calm conditions, divers should always carry appropriate dive insurance that covers recompression chamber treatment and emergency evacuation. The nearest major medical facilities and recompression chambers would likely be in Bali or Lombok, implying a significant evacuation time in case of a serious incident. Site-specific hazards are minimal, but divers must adhere strictly to guidelines for interacting with whale sharks: maintain a minimum 3-meter distance, never touch or ride the animals, and avoid flash photography. Always follow your dive guide's instructions, especially when diving near fishing platforms, to ensure both diver and marine life safety.
