The Syrena Cruises anchors at Hang Trong. Hang Trong, or Drum Cave, refers to a nearby cave that earned its name as a result of the sound made as the wind blows through its stalagmites and stalactites.
The waters here are quiet for swimming and there is a lot to explore by kayak.
Depending on conditions there are as many as five potential anchorage spots. Though Hang Trong is the most used, conditions may mean the vessel's captain opts for another site.
