Asho's Gap
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.
Asho's Gap is Coral Bay's most dependable appointment: a cleaning station where reef mantas bank in slow circuits while cleaner wrasse work their undersides, and grey reef sharks queue for the same service. The drill is simple and strict, settle low and to the side, keep off the station, and let the animals fly the pattern. Even without mantas the gap earns its keep with turtles, sweetlips, and coral heads in easy depth, but when a manta shadow slides overhead in ten meters of water the site explains why Coral Bay guards its reputation so carefully.
The moment you come for: Manta cleaning station in easy depth, queuing reef sharks, tight approach etiquette that works
Topography: Coral heads and a cleaning-station bommie in a break in the reef near Coral Bay
Entry: A short run from Coral Bay; briefings emphasize station etiquette before anyone rolls in.
Know before you splash
Hazards: Little beyond diver discipline; shallow enough for generous no-stop time.
Conservation: Cleaning stations fail if crowded: hold position where the guide places you and never hover over the bommie.
