Diving & Snorkeling in Dong Island is a guided underwater excursion off the coast of Lý Sơn, a volcanic archipelago in central Vietnam. The activity takes participants to coral reefs and rocky outcrops around Dong Island, where visibility often reaches 10-15 metres. Certified instructors lead each session, and all snorkeling gear and dive tanks are provided.
What to expect
- Sessions run 2-3 hours, including a 20-minute boat ride from Lý Sơn's main harbour to Dong Island.
- Two guided dives for certified divers, or a single snorkeling tour for beginners, with wetsuits, masks, fins, and buoyancy aids included.
- See hard coral gardens, schools of fusiliers, and occasional reef sharks or sea turtles near the island's submerged volcanic rock formations.
- Suitable for ages 10 and up; non-swimmers can join the snorkeling option with a floating ring and instructor supervision.
- All participants receive a safety briefing on reef etiquette and local marine life before entering the water.
- After the activity, a freshwater rinse and changing cabin are available on the support boat.
