Dive Site: Manado Tua

About Manado Tua

Manado Tua, or 'Old Manado,' is one of five islands that form the Bunaken Marine Park, a celebrated marine protected area in North Sulawesi, Indonesia. This site is distinguished by its unique topography, featuring steep walls that plunge past 80 meters, creating a habitat rich in both corals and diverse fish species. As a dormant volcano, Manado Tua provides a dramatic backdrop both above and below the water, contributing to the distinct character of its dive sites. The underwater landscape around Manado Tua is primarily composed of vertical walls adorned with extensive hard and soft corals, large barrel sponges, and sea fans. Depths range from shallow reef tops at 5 meters down to significant drop-offs. The visibility is often exceptional, typically between 20 to 35 meters, allowing for clear views of the vibrant ecosystems that thrive along these dramatic formations. Divers can expect to encounter a wide array of marine life, from schools of reef fish like pyramid butterflyfish and fusiliers to larger pelagic species such as whitetip reef sharks, eagle rays, and dogtooth tuna. Green and hawksbill turtles are common residents, often seen gliding along the walls. The area also hosts various macro critters, including nudibranchs and ornate ghost pipefish, especially in shallower, more sheltered spots. The diving experience at Manado Tua caters to various skill levels, with some sites offering gentle drifts along the walls, while others present stronger currents suitable for advanced divers seeking pelagic action. Most diving is conducted via day boats from nearby resorts, often as part of a multi-site itinerary within the Bunaken Marine Park, making it an integral part of the region's world-renowned diving offerings.

Conditions & Currents

Currents at Manado Tua can vary significantly by dive site and tidal conditions. While some areas offer gentle to mild drifts along the walls, sites like Tanjung Kopi are known for moderate to strong currents that can rip, attracting pelagic action. Dive plans are often dictated by current direction, often involving drift dives where divers enter upstream and are carried along the reef. Guides frequently instruct divers to go 'reef left' or 'reef right' depending on the current. Visibility generally ranges from 20 to 35 meters, but can fluctuate at sites with strong currents or plankton blooms. Water temperatures remain consistently warm at 28-29°C. Divers should be comfortable with varying current intensities and be prepared for potential strong drifts, especially at pelagic-rich sites, making advanced experience beneficial for certain locations.

Dive profile & how the dive runs

Dive profiles at Manado Tua typically begin with a boat drop directly onto the reef, often a shallow shelf before a dramatic wall. Divers descend to a maximum planned depth, frequently 25-30 meters, following the vertical wall either 'reef left' or 'reef right' depending on current direction. The route usually involves a drift along the wall, observing the vibrant coral formations, whip corals, and gorgonians, with frequent stops to spot smaller marine life in cracks and crevices. At sites with stronger currents, divers may hold onto the reef or take shelter in down-current eddies to watch schooling fish and pelagics. The turn point is often determined by air consumption or current changes. The ascent usually involves a gradual return to shallower depths, with a safety stop conducted over the reef top, which often hosts diverse marine life suitable for extended observation.

Underwater photography

Manado Tua offers excellent opportunities for both wide-angle and macro photography. For the dramatic wall topography and schools of fish, a wide-angle lens (e.g., 10-17mm or 16-35mm) is ideal, capturing the vastness of the drop-offs and large formations like barrel sponges. When strong currents bring in pelagics like eagle rays or sharks, a wide-angle setup is also preferred. For macro subjects such as nudibranchs, pygmy seahorses, and ornate ghost pipefish found in sheltered areas or on the reef top, a dedicated macro lens (e.g., 60mm or 100/105mm) with close-up diopters is essential. External strobes are recommended for both disciplines to bring out the true colors of the corals and marine life, especially at depth. Maintain excellent buoyancy control to avoid damaging delicate corals or silting up the environment.

Getting there & logistics

Access to Manado Tua typically begins with a flight into Sam Ratulangi International Airport (MDC) in Manado, North Sulawesi. From Manado, a short 45-minute to one-hour boat transfer will take you to resorts located on Bunaken Island or other islands within the marine park, or directly to day boats for diving. Most operators offer daily dive trips, often including 2-3 dives per day, with Manado Tua being a frequent stop due to its proximity and iconic status. Dive packages usually include full board at resorts, simplifying logistics. An entrance fee of 25,000 IDR per person per visit is required for Bunaken Marine Park. This site is commonly combined with other Bunaken Marine Park dives and sometimes with Lembeh Strait for a comprehensive North Sulawesi dive experience.

Safety & environment

For diving at Manado Tua, comprehensive dive insurance covering hyperbaric treatment and emergency evacuation is highly recommended. The nearest recompression chamber is located in Manado, approximately 1-2 hours away by boat and land, highlighting the importance of cautious diving practices. Site-specific hazards include potentially strong and unpredictable currents, especially at certain points like Tanjung Kopi, which demand good dive planning and comfort with drift diving. Always follow your dive guide's instructions regarding entry points, current conditions, and maximum depths. Maintain excellent buoyancy to avoid damaging the protected coral reefs. It is advisable to dive within your training and experience levels, particularly at advanced sites known for strong currents.
