Commenting on the S-shaped land, Business Insider said: “For a truly one-of-a-kind experience, head to southern Vietnam's Mekong Delta and discover a world that revolves around the river.”

The most popular activity for travelers to the region is guided boat tours through the maze-like Mekong and its many offshoots. There, travelers will see incredible floating markets like the one in Can Tho, where bustling crowds of locals navigate from boat to boat trading their goods.

Travelers can also get a breathtaking view of the delta from Sam mountain near Chau Doc.
