Coral Seafan, a short boat ride from Beqa Lagoon, might sound like just another easy lagoon dive, but we think it’s a brilliant spot to slow down and really look. Dropping to a comfortable 19m max, the current is often mild, letting you hover and appreciate the detail. We love how the soft corals sway, creating a gentle, undulating landscape, and the sea fans here are just enormous. We’ve spent entire dives just watching the anemonefish; the Fiji, Clark’s, and Pink varieties all seem to call this place home. Keep an eye out for the Threespot Righteye Flounder, almost invisible on the sandy patches, and the vibrant Scarlet wrasse flitting between coral heads. It’s not about huge pelagics here, though a Porcupine ray might glide past if you’re lucky. Instead, Coral Seafan excels at intricate reef life and makes for a fantastic long, relaxed dive, perfect for photographers or anyone wanting to truly immerse themselves without fighting a strong current.
