Manta Point: The Manta Ray Wonderland
Manta Point is one of the most famous dive sites in Komodo National Park, celebrated for its reliable sightings of majestic manta rays. Located near the island of Nusa Penida, this site is a must-see for those diving from a yacht, especially if you’re looking for an unforgettable experience.

For beginners, Manta Point is an excellent spot for snorkeling as well. The shallow waters afford great opportunities to observe these gentle giants up close while remaining safe. Prices for a snorkel trip from a charter boat can range from $60 to $120 (IDR 900,000 to IDR 1,800,000), depending on the package selected.
Castle Rock: The Thrill-Seeker’s Delight

The depth here varies from 10 to over 30 meters, with the best visibility occurring between April and November.
While diving, you’ll likely encounter large pelagic species such as barracudas, trevally, and even sharks, which make this site an absolute paradise for those seeking big fish encounters. Liveaboard trips often include stops at Castle Rock, with prices typically around $350 to $550 (IDR 5,250,000 to IDR 8,250,000) for a 3-day, 2-night itinerary that covers multiple dive sites.
Batu Bolong: A Coral-Filled Paradise
Known for its breathtaking coral formations, Batu Bolong is another highlight in the Komodo dive circuit. This dive site is often touted as one of the best places to witness the beauty of the underwater world, making it a favorite among both snorkelers and divers alike.
The best time to dive Batu Bolong is also from April to November, when conditions are calmer, and visibility is high. You can expect dives to range between 10 to 30 meters deep, opening up opportunities to see not only the coral but also various fish species that thrive in this vibrant ecosystem.
For those snorkeling from a charter boat, Batu Bolong is incredibly user-friendly. The shallow areas are teeming with colorful reef fish, making it suitable for all skill levels. Prices for snorkeling trips typically range from $50 to $100 (IDR 750,000 to IDR 1,500,000), with many charters providing gear and guidance.
Diving Conditions and What to Expect
Diving in Raja Ampat offers a variety of conditions depending on the site. At Manta Point, expect mostly calm waters, making it excellent for beginners and advanced divers alike. Meanwhile, Castle Rock presents a more challenging environment with significant currents. For divers looking to experience a mix of both macro and large fish encounters, knowing which sites to choose is essential.
Macro vs. Big Fish Diving
If you’re interested in macro photography, sites like Cape Kri and Mioskon are better options, showcasing smaller, unique creatures. However, for those eager to catch sight of large pelagic species, Manta Point and Castle Rock are your best bets. Divers often find the thrill of spotting a manta ray or a busy school of trevally at these iconic locations unbeatable.
