Castle Rock

Castle Rock, Komodo National Park

Welcome to Castle Rock, North Komodo’s signature pelagic arena and one of the most exhilarating dive sites in Komodo National Park. Situated approximately two kilometres off Gili Lawa Laut in the Lintah Strait, this fully submerged seamount rises dramatically from deep open water to within 4-7 meters of the surface, acting as a magnet for an incredible array of marine life.

Dive Site Overview

• Difficulty: Advanced
• Certification Required: Advanced Open Water certification is essential for divers wishing to explore this dynamic dive site.
• Site Type: Seamount, Pinnacle, Drift
• Depth: Divers will explore depths ranging from 4 meters at the pinnacle's peak down to a maximum depth of 40 meters, with much of the action typically found between 10 and 25 meters.
• Current: Known for its strong currents, Castle Rock offers an electrifying drift diving experience. The nutrient-rich tidal currents that sweep through the Lintah Strait between the Flores Sea and the Indian Ocean are the lifeblood of this vibrant ecosystem. Divers should be prepared for a negative entry, dropping fast through the blue water, as surface currents can be particularly strong.
• Temperature: The water temperature at Castle Rock typically ranges from 24°C to 29°C, providing comfortable diving conditions year-round.
• Hazards: Strong currents are the primary hazard, along with potentially challenging surface conditions. We recommend divers be proficient in current management and comfortable with the use of a reef hook to secure themselves and observe the spectacular show.

Marine Life at Castle Rock

Castle Rock is renowned as one of Komodo's most reliable sites for encountering large pelagic species. The powerful currents ignite a feeding chain, attracting an abundance of predators:

• Sharks: Divers can almost guarantee sightings of Whitetip Reef Sharks and frequently encounter Grey Reef Sharks patrolling the deeper sections and making sweeping passes.
• Pelagics: Walls of schooling Fusiliers and surgeonfish shimmer over the reef, attracting formidable hunters such as Giant Trevally, Bigeye Trevally, and Dogtooth Tuna. Keep an eye out for impressive tornadoes of Chevron Barracuda swirling overhead.
• Rays & Dolphins: We often encounter graceful Spotted Eagle Rays gliding past, and on lucky days, playful Bottlenose Dolphins may buzz the safety stop.
• Occasional Sightings: For the truly fortunate, there have been rare sightings of Whale Sharks, Reef Mantas, and even the occasional Hammerhead Shark, adding to the site's allure.
• Reef Life: While famous for its pelagics, on calmer days, divers can explore the pinnacle's slopes where healthy hard corals host various groupers, sweetlips, and the impressive Bumphead Parrotfish. The pinnacle is also home to numerous octopus, pygmy seahorses, and turtles, providing diverse photographic opportunities.

To fully appreciate the spectacle, divers typically make a negative entry and descend quickly. Once at depth, often around 20-25 meters, divers can use a reef hook to anchor themselves in a sheltered position and witness the incredible feeding frenzy unfold. The top of the pinnacle, around 5 meters, makes for an excellent safety stop, often still teeming with hunting trevallies.
