Xep Islet or Layer Islet is a huge, multi-layered, square piece of stone which looks like an Egyptian pyramid built in the middle of the Bai Tu Long Bay, Cam Pha District.
Boating past the Am Islet some 20 minutes, we see Mat Quy Islet or Monster Head Islet, which protrudes about 30-35 m from the waters of Bai Tu Long Bay.
Some 30-minute boating away from the Con Coc Islet, on the way to the Ba Trai Dao (Three Peaches) Island, visitors see a pen bobbing (But Islet) in the seawaters.
