Cham Island, Uncrowded: A Private Snorkeling Escape off Hoi An
Slip past the crowds by speedboat and dive straight into Vietnam’s brightest coral gardens.
At Cua Dai, the morning river exhales into the sea and the speedboat answers, skimming out from Hoi An’s wide estuary as if tugged by the horizon. The Cham archipelago rises ahead—green-backed, cliff-shouldered, the color of old jade—and the water shakes off river silt to turn glassy, blue, and insistent. Fishing coracles bob like commas in a sentence you’re about to finish. The engine leans into a salt-wet sprint. The coast falls behind.
Trail Wisdom
Go Early for Calm Water
Morning departures often mean smoother seas, better visibility, and fewer boats at the reefs.
Wear a Rash Guard
Skip heavy sunscreen and protect skin with UPF layers—better for you and the coral.
Float, Don’t Stand
Avoid kicking or stepping on coral; keep your body horizontal and use gentle fin strokes.
Motion Sickness Plan
Take seasickness meds 30 minutes before boarding if you’re sensitive; the short crossing can be choppy.

Conservation Note
Use mooring buoys rather than anchors, avoid touching coral, and never feed fish. Reef-safe sun habits protect this sensitive marine ecosystem.
The Cham Islands supported Champa sailors for centuries and sit offshore from Hoi An, a former international trading port. In 2009, UNESCO recognized the islands and Hoi An as a combined Biosphere Reserve.
