Ong Can - One of Vietnam's 11 sea territorial landmarks
Hon Ong Can is point A9 - one of the 11 points on the straight baseline along the Vietnamese mainland.
Ngo Tran Hai An, a travel blogger, has conquered different journeys along Vietnam and visited many countries around the world. Below is Hai An's share of the journey to conquer landmark A9 on the baseline defining Vietnam's territorial sea. Previously, he has conquered the landmarks A3, A4 and A5 in Con Dao.

| "In addition to the passion for conquering, I also want to spread the stories behind my photos in order to praise Vietnam's beauty and increase the pride and affection of people towards Vietnam's borders, territories and islands", shared blogger Hai An. (Photo: VN Express) |
 |
| In addition to its unspoiled beauty, Ong Can is also the landmark A9 of Vietnam's baseline. Around Ong Can island exist lots of reefs, which makes the island difficult to be approached by boats. (Photo: VN Express) |

| From Eo Gio cape, the tourists pass through Hon Co. The farther from the shore they got, the stronger a wave pushed. About 15 minutes later, Ong Can island appeared. Ong Can includes three consecutive islands, about 200 meters apart, the landmark is set up on the furthest one. (Photo: VN Express) |
 |
| When the canoe approached, everyone was stunned. In the middle of the immense sea stands a giant rock of more than 20 meters high, which cracked in half to create a deep gap beyond the crashing waves. The island is covered with sharp oyster shells. (Photo: VN Express) |
 |
| Ong Can was formed due to volcanic eruption millions of years ago. As the lava stream encountered seawater, it suddenly froze to create an island. The island is located at 13 ° 53’57 ″ North 109 ° 21’08 ″ East, about 7 km from the shore, about 140 km from point A8 to the south, about 170 km from point A10 to the north. The island belongs to Nghiem Kinh Chieu island cluster, Nhon Ly commune. Ong Can is about 200 m long, and the widest part of the island is about 95 m. (Photo: VN Express) |

| Not far from the landmark is the national coordinate point built by the Ministry of Natural Resources and Environment in June 2017. Ong Can plays an important role in determining the width of Vietnam's territorial sea under the 1982 United Nations Convention on the Law of the Sea. (Photo: VN Express) |
 |
| After about 30 minutes of exploring the island, realizing the waves were getting stronger, the group of tourists left the island. They hope to have a chance to explore the last landmark on Con Co island in the near future. (Photo: VN Express) |
