Offshore Sanctuary: Snorkeling the Living Reefs of Cham Island
A living reef reserve a short boat ride from Hoi An—where coral gardens meet local fishing life.
Continue ReadingThe engine thumps beneath your feet and the shore of Hoi An slims into a watercolor strip: ochre buildings, lanterns fluttering in a breeze that smells of wood smoke and lemongrass. Out past the fishing boats and the breakwater, the South China Sea opens into a different kind of quiet — a bright, clean silence broken only by the slap of the boat against the swell. Ten minutes becomes thirty; the town recedes and, somewhere between the horizon and the sun, Cham Island appears: a small, forested silhouette ringed in white sand and turquoise. You anchor and the sea dares you forward. It’s time to get wet.

Bring or Rent Proper Snorkel Gear
A well-fitting mask and fins make longer swims more comfortable and let you see more without tiring quickly.
Use Reef-Safe Sunscreen
Protect the coral as you protect yourself—chemical sunscreens can harm marine life, so choose mineral-based formulas.
Carry Small Change
Island eateries and vendors often accept only cash; keep Vietnamese dong for lunch, drinks, and tips.

Photographer's Notes
Photographer's Notes
Bring a waterproof camera or housing for close reef shots; shoot in the morning when light is softer and the water is clearest. Use a snorkel mask with a wide field of view and consider a floating wrist strap for your camera. For village scenes, lower shutter speed for water motion and use a polarizing filter when shooting from shore to cut glare.
