Dive Site: Bunaken Wall

About Bunaken Wall

The Bunaken Wall, located in the Bunaken Marine Park off North Sulawesi, Indonesia, is renowned as one of the world's premier wall diving destinations. This protected area, established in 1991, features dramatic drop-offs that plunge past 100 meters, showcasing an extraordinary biodiversity within the Coral Triangle. Divers explore sheer coral faces adorned with barrel sponges, vibrant sea fans, and abundant soft corals, all while enjoying often spectacular visibility exceeding 30 meters. The park's unique underwater topography and the influence of the Indonesian Throughflow create nutrient-rich waters that support a thriving ecosystem. While some sites, like Lekuan III, offer gentler currents suitable for all levels, others, such as Lekuan I and II, experience stronger flows that attract pelagic species. This dynamic environment makes Bunaken suitable for a range of divers, from beginners on sheltered walls to advanced divers seeking exhilarating drift dives with larger marine life. Key marine residents include numerous green and hawksbill turtles, whitetip and blacktip reef sharks, and schooling pyramid butterflyfish. Pelagic encounters can include eagle rays, dogtooth tuna, giant trevally, and even occasional dugongs or mola mola at sites like Tanjung Kopi. The consistent warm water temperatures, ranging from 26 to 30 °C, mean a 3mm shorty is typically sufficient for comfort, enhancing the overall dive experience. Diving logistics are straightforward, typically involving day trips from resorts on Bunaken, Siladen, or other nearby islands. Access is primarily via a short boat ride from Manado after flying into Sam Ratulangi International Airport (MDC). The combination of accessibility, healthy reefs, and diverse marine life solidifies Bunaken Wall's reputation as a world-class dive destination.

Conditions & Currents

Currents at Bunaken Wall vary significantly depending on the specific dive site and lunar cycle. Many main wall sites experience gentle to moderate currents, making them suitable for relaxed drift dives and divers of all experience levels. However, sites like Lekuan I and II, as well as Tanjung Kopi, can encounter moderate to strong currents, particularly during full and new moons. These stronger currents often attract larger pelagic species and necessitate good buoyancy control and current awareness. Entry techniques may include giant strides from the boat, often initiating a drift along the wall. Visibility remains excellent, generally between 20-35 meters, even with currents, ensuring clear views of the abundant marine life. Divers should always consult with their guide regarding specific site conditions before entering the water.

Dive profile & how the dive runs

Dives at Bunaken Wall typically begin with a boat entry onto the shallow reef top, usually around 5 meters, before gliding over the edge to explore the dramatic vertical walls. For sites like Lekuan I and II, the drop-off is immediate. Divers then drift along the wall, which plunges to depths well beyond 40 meters, often reaching over 100 meters. The route often involves exploring crevices, overhangs, and the vibrant coral formations that adorn the wall face. Depths are generally maintained between 12-25 meters to maximize bottom time and light exposure on the reef. The turn point is usually dictated by air consumption or current direction. Safety stops are comfortably conducted on the shallow reef gardens at the top of the wall, where schools of small fish and abundant hard corals offer a pleasant end to the dive.

Underwater photography

Bunaken Wall offers excellent opportunities for both wide-angle and macro photography, so consider a setup that allows for quick transitions if possible. For wide-angle shots, capture the dramatic wallscapes adorned with large barrel sponges, sea fans, and abundant soft corals, especially with the clear visibility and vibrant light penetration in the shallower sections. Include divers to convey scale against the immense walls. For macro subjects, explore the numerous cracks and crevices for nudibranchs, moray eels, and small reef fish. Look closely at the corals for pygmy seahorses and other tiny critters. Given the potential for currents, maintaining good buoyancy is crucial to avoid touching the reef and to steady your shots. A powerful strobe is beneficial to bring out the true colors of the corals and marine life, particularly at deeper points along the wall.

Getting there & logistics

Access to Bunaken Wall primarily involves flying into Sam Ratulangi International Airport (MDC) in Manado, North Sulawesi. From Manado, it's a 45-minute to one-hour boat ride to resorts located on Bunaken Island, Siladen, or other islands within the marine park. Most diving is conducted via day boats operating from these resorts, typically offering three dives per day. A typical trip length can range from 5 to 7 days, allowing for comprehensive exploration of the various wall sites. The Bunaken Marine Park requires an entrance fee, which is usually included in dive package costs. Many itineraries combine diving in Bunaken with muck diving in the nearby Lembeh Strait for a varied North Sulawesi diving experience.

Safety & environment

Diving at Bunaken Wall generally has a good safety record, but divers should always carry appropriate dive insurance that covers emergency medical treatment and evacuation. The nearest recompression chamber is located in Manado, approximately an hour's boat ride from Bunaken. Site-specific hazards include potential strong currents at certain locations, particularly Lekuan I and II and Tanjung Kopi, which require good buoyancy control and experience with drift diving. Always follow your dive guide's instructions, especially regarding current conditions and appropriate entry/exit procedures. Maintaining proper depth and bottom time is crucial, especially when exploring walls that plunge to great depths. Ensure your equipment is well-maintained and conduct thorough buddy checks before each dive.
