More ways to explore the area's outdoor wonders
The speedboat cuts across Nha Trang Bay and salt spray slaps your forearms as the shoreline shrinks behind you. Clear water opens beneath the bow; coral gardens flicker with the busy language of fish. On arrival at Coral Bay or Con Se Tre, instructors fit helmets and brief the group — then the ocean pulls you down in a steady, breathable hush as you walk the sandy seabed among parrotfish and branching coral.
