Con Co Island is located in the east of Quang Tri province, about 13-15 nautical miles (around 30 km) from Cua Viet Port (Cua Viet commune, Gio Linh district). This is the smallest island district in Vietnam, covering an area of only about 2.3 km².
Located right on the 17th parallel, it was once a "steel fortress" during the resistance war against America, and is now point A11 on the baseline defining national territorial waters. More than 70% of the island's area is covered by 3-canopy tropical primary forest, one of the rare ecosystems in Vietnam that remains almost intact.
Highlights:
- Blue sea, white sand, and rich coral reefs.
- Attractions: National Flagpole (38.8m high), Nghe Wharf, Tranh Wharf, Traditional House, Memorial Monument, military medical bunker, primary forest, lighthouse...
- Fresh, peaceful air and less crowded compared to major tourist islands.
Ideal time: March to June (calm seas, low rainfall). From July to November, weather should be monitored closely due to potential storms.
