Batu Bolong: The Most Famous Dive Site in Komodo

Where is Batu Bolong?

Batu Bolong sits in the central area of Komodo National Park, between Komodo Island and Tatawa Kecil. The site is famous for the small rock sticking out above the water surface. The name “Batu Bolong” means “hollow rock” in Indonesian, referring to the hole found in the rock formation above sea level.

Underwater, the site is actually a submerged pinnacle rising from deep water. The reef starts around 5 meters and drops down beyond recreational diving limits. Because of this structure, ocean currents flow strongly around the pinnacle, bringing nutrients that support an incredible amount of marine life. Batu Bolong is also considered one of the most iconic spots among the many dive sites in Komodo because of its dense fish population and colorful coral gardens.

Why Divers Love Batu Bolong

There are many amazing dive spots in Komodo, but Batu Bolong stands out for one main reason: the amount of life underwater. The reef is covered with healthy hard and soft corals. Schools of anthias, fusiliers, and snapper surround divers almost everywhere they look. Larger pelagic species also patrol the area, especially when the current becomes stronger.

Divers often describe Batu Bolong as an “underwater aquarium” because there is always something happening around the reef. One moment you are watching tiny reef fish hiding inside the coral, and the next moment a giant trevally or white-tip reef shark appears from the blue.

Visibility is often excellent, especially during the dry season. On good days, divers can enjoy visibility reaching more than 20 meters, making the underwater scenery even more impressive. For underwater photographers, Batu Bolong is one of the best places in Komodo to capture colorful reef scenes filled with movement and marine life.

Marine Life and Diving Conditions

Batu Bolong is famous for its biodiversity. Because of the nutrient-rich currents, the reef attracts both small reef creatures and larger predators.

Some of the marine species commonly seen here include:

• White-tip reef sharks
• Napoleon wrasse
• Giant trevallies
• Barracudas
• Green turtles
• Tuna
• Sweetlips
• Manta rays
• Anthias and fusiliers

Macro lovers may also spot nudibranchs, frogfish, and small critters hidden between the coral formations. Although Batu Bolong is beautiful, it is not considered an easy dive site. Currents can become strong and unpredictable depending on tides and moon phases. Divers need good buoyancy control and should always stay close to their guide.

Most dive operators recommend Batu Bolong for intermediate to advanced divers. However, newer divers can still improve their confidence and skills by joining a diving course in Komodo before exploring more challenging dive sites. The dive itself is usually done as a drift dive. Divers descend quickly near the reef and stay protected behind the pinnacle while enjoying the marine life around them.

Best Time to Dive Batu Bolong

Batu Bolong can be dived year-round, but conditions are usually best between April and November. During these months, the sea around Labuan Bajo is generally calmer, visibility becomes clearer, and boat trips to Komodo National Park are more comfortable.

Water temperatures in Komodo usually range between 24°C and 29°C depending on the season and dive location. Cooler temperatures sometimes appear in the southern dive sites, while central Komodo often remains warmer. The dry season is especially popular among divers because conditions are more stable and underwater visibility becomes better for photography.

Many travelers visiting Labuan Bajo choose to combine Batu Bolong with other nearby dive locations through fun diving trips in Komodo, allowing them to experience the incredible variety of marine life across the national park.

Diving Batu Bolong from Labuan Bajo
