Dive site: Cave I - Nusa Menjangan
Time to destination: 45min
Difficulty: 2 to 3
Current: little to medium
Tips: impressive Drop Off
Further along from Post II is a mooring buoy which is half way along the drop off.
If the current is in the opposite direction both dives and snorkelers can start here and head back to Post II with the current.
You can also continue on from here towards the mangrove area, before the wall peters out to become a steep sandy slope.
Though it continues as wall for quiet some distance beyond the buoy.
