15. Rolling Down a Very Short River

At its longest constant stretch, the Roe River spans only 61 meters, and its depth near the mouth ranges from 6 to 8 feet. This fascinating natural feature attracted attention for its brief journey, earning its place in record books until the category was retired in 2006.

The current title of the world’s shortest river has since been claimed by the Reprua River in the Republic of Abkhazia. Flowing just 18 meters, the Reprua stands as one of the shortest and coldest rivers, particularly noted for its proximity to the Black Sea coast.
