Shark Close

Shark Close does what the label says: it puts divers and grey reef sharks in the same modest volume of water. The site, off Alor's northwest coast near Sebanjar, gained its reputation in the years when local boats drew the sharks in close; the practice has faded, but the residents remain, cruising the terraces where the reef shelves toward the strait's deep water. Whitetips rest in the sand cuts, schooling fusiliers and surgeonfish work the slope, and the same cold pulses that power the rest of the Pantar Strait sweep through mid-dive. It is a straightforward, slightly stern dive whose appeal is dependable shark traffic without cages, feeding, or fuss.

The moment you come for: Grey reef sharks at close quarters; cool, fish-rich strait water; uncrowded big-animal diving.

Topography: Sloping reef and rubble terraces off the northwest Alor coast, falling toward deep water.

Current: Exposed to the strait's flow; dived on selected tides with drift procedures.

Hazards: Current, depth, and thermoclines together shorten safe bottom time; plan conservatively this far from help.

Conservation: Historic provisioning has ended; treat encounters as wild and unbaited, and keep behavior accordingly neutral.

Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
