In the itinerary of Thien Cung Cave – Dau Go Cave – Ti Top Beach, after visiting Thien Cung Cave and Dau Go Cave, one needs 10 minutes boating to the Cho Da Islet or Stone Dog Islet or Dinh Huong Islet. Some 8 m up the islet one can figure out a piece of stone in the shape of a dog sitting with its back to the sea, standing guard for the safety of seagoing boats for millions of years.
