Citrus Ridge – Reef in Raja Ampat, Indonesia

Name: Citrus Ridge
Address: Raja Ampat

About Citrus Ridge

Citrus Ridge is a renowned dive site in Raja Ampat, located in a natural channel separating Gam Island from Yanggelo. This site features a vibrant coral slope that descends gradually, transforming into denser, more colorful growth. Its name comes from a large pinnacle around 14 meters deep toward the center of the channel, which is blanketed in stunning soft corals in shades of orange, yellow, and red, resembling a field of citrus fruit. The rich nutrients from nearby mangrove forests contribute to an explosion of marine life, making it a visually spectacular dive. The topography transitions from sporadic rock formations and bommies on the gentle slope to a magnificent main pinnacle teeming with life, ultimately leading to the opposite slope. Divers encounter abundant crustaceans on sandy bottoms, ghost shrimps and clownfish in anemones, and a kaleidoscope of reef fish. Large schools of pelagic species, including barracudas, jackfish, and snappers, are frequently observed converging around the central pinnacle, attracted by the nutrient-rich currents. Green turtles are often seen resting on corals, while critters like nudibranchs, octopuses, and even wobbegong sharks inhabit the reef's crevices. Citrus Ridge can experience moderate to strong currents, often making it an exhilarating drift dive. Entry points are secluded and safe, with dives adaptable depending on current direction, though swimming against the flow is not advised. Though currents can be intense, the site is generally accessible to intermediate and advanced divers comfortable with moving water and maintaining good buoyancy. Visibility typically ranges from 15 to 30 meters, with optimal conditions during the dry season (October to April). Dives often end in shallow mangrove corners or fringing reefs, providing a tranquil ascent after the vibrant activity.

Conditions & Currents

Currents at Citrus Ridge can range from moderate to strong, often flowing consistently along the reef, making it an ideal site for drift diving. Divers should be prepared for moving water and maintain good current control, especially around the large sand slope halfway through the dive where currents can intensify, requiring stronger finning. The current direction dictates the dive plan, with entry typically upstream to allow for a natural drift along the ridge. While exhilarating, these currents demand intermediate to advanced diving skills and solid buoyancy control to fully appreciate the site's vibrant reef life. Visibility usually remains good, but plankton blooms, sometimes associated with currents, can occasionally reduce clarity.

Marine life & sighting chances

Dive profile & how the dive runs

Your dive at Citrus Ridge begins with a tender drop-off at the end of the ridge, specifically where the current originates, facilitating a comfortable drift. You'll descend to approximately 25 meters, exploring the vibrant slope of the ridge. The path meanders along a terrain of coral gardens and reef outcrops, showcasing the site's namesake orange and yellow soft corals. Halfway through the dive, you'll encounter a large sand slope where currents can pick up, requiring a more active finning effort to cross. Once past this section, the current typically lessens, allowing for continued exploration of the rich reef. The dive concludes with a gradual ascent along the reef to a safety stop at 5 meters, often offering views of mangroves and possibly archerfish activity at the surface.

Underwater photography

Citrus Ridge offers exceptional opportunities for both wide-angle and macro photography, thanks to its vibrant coral coverage and diverse marine life. For wide-angle shots, utilize the consistent visibility and colorful soft corals, particularly around the large pinnacle at 14 meters, to capture sweeping reefscapes and schooling fish. A wide-angle lens with external strobes will enhance color and detail. For macro subjects, explore the numerous nudibranchs, eels, and camouflaged scorpionfish along the slope; a macro lens with a snoot can isolate these smaller wonders. Given the potential for moderate to strong currents, precise buoyancy control is crucial to avoid damaging delicate corals and to hold position for steady shots.

Getting there & logistics

Accessing Citrus Ridge typically involves flying into Sorong (SOQ), which serves as the primary gateway to Raja Ampat. From Sorong, divers usually transfer to a liveaboard or take a ferry to Waisai, then travel to local resorts. Liveaboards offer the most comprehensive way to explore Raja Ampat's remote sites, with itineraries often ranging from 7 to 12 days, covering various regions including the North, Central, and South. Citrus Ridge is frequently included in itineraries exploring the Gam Island area. All divers are required to purchase a Raja Ampat Marine Park Entry Permit, valid for one calendar year. Given the remote nature of the region, booking liveaboards well in advance, especially for the high season, is highly recommended.

Safety & environment

Diving at Citrus Ridge requires careful attention to safety protocols due to potentially strong currents; divers should always follow their guide's instructions regarding entry and drift techniques. Good buoyancy control and current experience are essential. Recompression chambers are available in Sorong, but evacuation from remote dive sites can be time-consuming, making comprehensive dive insurance, including coverage for emergency medical evacuation and recompression treatment, absolutely mandatory. Divers should always carry an SMB for surfacing in strong currents and ensure they are adequately hydrated to prevent decompression sickness.

Why dive Citrus Ridge from a liveaboard?

Citrus Ridge is one of Raja Ampat, Indonesia's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
