Big Drop-Off has a vertical wall that stretches alongside Ngemelis Island. The wall deserves to be seen from all directions. It is possible to spot a big chain connected to a 2m/6ft steel sphere all the way from WWII that used to stop Japanese from coming to this channel. The end of the reef goes down to 274m/899ft. Sometimes a light current can occur.
