The Big Drop Off is a vertical wall that falls from near the surface to more than 285 m. It is a straightforward wall dive in moderate to no current, with sharks working the face and nothing but blue below.
Also known as Big Drop-Off, The Big Drop Off, Ngemelis Wall.
Where it is and how deep
7.1136° N, 134.2410° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
Guides keep the group between 1 and 37 m (3–120 ft) on the face. The site is dived in one of two directions, chosen by the current, and works equally well either way. Grey reef and whitetip sharks patrol back and forth along the drop-off, and a solitary leopard shark sometimes joins them. Visibility runs 15–30 m (50–100 ft), depending on the direction of the tide.
