July 1, 2026
6 min read
Discover the dynamic diving experience at Castle Rock and Crystal Rock in North Komodo, where strong currents sweep through thriving pinnacles teeming with pelagic life. This adventure is a must for experienced divers seeking encounters with eagle rays, white-tip sharks, and lively marine biodiversity within the protected waters of Komodo National Park.
Exploring Castle Rock and Crystal Rock
Castle Rock and Crystal Rock are two of the most renowned dive sites in North Komodo, offering an exhilarating dive experience characterized by strong currents and diverse marine life. Both sites are pinnacles rising from the depths, surrounded by nutrient-rich waters that attract pelagic species. Divers can expect to encounter large schools of barracuda, trevally, and fusiliers, as well as solitary white-tip and black-tip reef sharks patrolling the area.
At Castle Rock, the top of the pinnacle is about 4-5 meters deep, making it ideal for divers to pause and observe the busy activity below. The currents, while challenging, create a thrilling underwater ride that brings divers face-to-face with the area’s dynamic ecosystem. Crystal Rock, located nearby, offers similar conditions with the added spectacle of colorful corals and the occasional appearance of dolphins and eagle rays. Both sites require a minimum of Advanced Open Water certification due to the demanding environment.
Diving Conditions and Seasons
Komodo National Park benefits from two distinct diving seasons. The dry season, from April to November, offers the best visibility, often exceeding 30 meters in North Komodo, with water temperatures ranging between 26-29°C. This period is ideal for exploring Castle Rock and Crystal Rock as the clearer waters enhance the visual spectacle of the marine life.
During the months of December to February, the focus shifts to the southern areas of Komodo, where nutrient-rich waters attract large manta rays. Water temperatures in these southern sites, including Manta Alley, can be cooler at 22–25°C. Despite the reduced visibility, the increase in plankton draws in mantas and other large pelagics, offering a different, but equally captivating, diving experience.

Komodo National Park is accessible via Komodo Airport (IATA: LBJ) located in Labuan Bajo on the island of Flores.

Once in Labuan Bajo, divers can join open-trip cruises, private charters, or speedboat day trips to reach the dives sites within the park. These options cater to various budgets and preferences, ensuring that the wonders of Castle Rock and Crystal Rock are within reach for those eager to explore.
