Just outside the colonial town of Suchitoto, El Salvador, lies Los Tercios Waterfall (Cascada Los Tercios)—a natural wonder famous not only for its cascading waters but also for its striking rock formations. The waterfall tumbles over a wall of perfectly shaped basalt columns, creating a breathtaking geometric backdrop that looks like it was carved by hand.

The unique hexagonal and rectangular rock columns were formed thousands of years ago by the cooling and contraction of volcanic lava. Over time, the elements sculpted the site into the dramatic scene we see today. The waterfall’s name, Los Tercios (“the thirds”), is thought to refer to the patterned division of the rock wall.

Interesting Facts
