Jina Pass
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
Jina is Kinasi's understudy and, on its day, the better dive. The southern pass moves less water, so its walls hold delicate growth the main channel cannot keep — fans, soft coral tufts, sponge in quantity — while still pulling in channel traffic: snapper walls, trevally raids, turtles, and rays in the chutes. Groups drift the wall on the making tide, tucking into undercuts to let the flow slide past. Because most operators default to Kinasi, Jina often comes up empty of other divers, and guides save it for the tides when it runs clean and green-free.
The moment you come for: Quieter channel drift with better-preserved wall growth
Topography: Channel walls with coral heads, undercuts, and sand chutes
Current: A second, quieter gate into the bay system; tide-timed like Kinasi but usually gentler.
Know before you splash
Hazards: Tidal current and surge at the seaward mouth.
Permits & rules: Marine-park daily fee applies.
Conservation: Marine-park rules apply; the soft growth on these walls is the reason to keep trim tight.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
