Edna’s Anchor

This dive site, known as Edna’s Anchor, offers an engaging exploration along a sand/reef edge that gradually descends towards a dramatic drop-off. The dive typically begins by following this reef line. The main attraction is the large anchor of the schooner Edna, which later sank in Atiu, found at approximately 24 meters depth nestled between two prominent coral bommies. Beyond this point, at about 30 meters, the reef transforms into a sheer wall that plunges straight down to an impressive depth of around 65 meters, resembling an underwater ski slope. The marine life at Edna's Anchor is diverse and vibrant. Divers can expect to encounter a variety of fish species including colorful parrotfish, camouflaged scorpionfish, elegant lionfish, and the distinctive crocodile needlefish. Schools of peacock groupers and damselfish add to the reef's activity. Green turtles are often spotted gliding gracefully. For macro enthusiasts, christmastree worms and pineapple sea cucumbers provide interesting subjects, while the hard corals, such as Porites, form the foundation of this thriving ecosystem. The best time to visit the Cook Islands for diving is typically during the dry season, from May to October, when visibility is generally excellent and the weather is calm. Edna's Anchor is particularly appealing for divers seeking a mix of historical wreck interest, beautiful reef formations, and the chance to encounter larger marine life. While the shallower parts of the reef edge are suitable for more experienced freedivers, the main features like the anchor and the deeper drop-off are best enjoyed by certified scuba divers, offering a rewarding experience for those comfortable with intermediate depths and beyond.
