4. Cau Treo / Nam Phao (Google Maps)
This is the most popular border crossing if you want to take the bus from Vientiane to northern part of Vietnam (Nghe An, Thanh Hoa, Ninh Binh, and Hanoi)

5. Chalo / Naphao (Google Maps)
This border is not popular among the tourists visiting the two countries, but it is the very interesting and promising one.

6. Lao Bao / Dansavan (Google Maps)
This is the border crossing for the ones travelling from Laos to central Vietnam (Hue, Danang, Hoi An), which has some of the most beautiful beaches in Vietnam (even the world).
In Laos side, the tourism does not touch this part at all. It is again because of the poor basic infrastructure. Moreover, some parts of the area are not opened to tourists yet (the part of Ho Chi Minh Trail in Laos), which attracts many curious eyes from all over the world.
7. La Lay / Lalay (Google Maps)
This newly opened border crossing is the convenient way for the tourists who want to connect between central Vietnam (Hue, Danang, Hoi An) and southern Laos (Bolaven Plateau, Pakse, Wat Phou, Champasak, 4000 Islands)
Notice: You cannot apply for Visa on arrival to Laos via this border as there is not enough equipment. Hence, please get your Lao visa ready before getting on the bus.
