Cascada Los Tercios, near Suchitoto, El Salvador, is a striking seasonal waterfall known for its unique hexagonal rock formations. Accessibility can be challenging, requiring a somewhat strenuous hike down to the base, making it less suitable for those with mobility issues. Solo visits are possible, but a local guide is recommended for safety and to learn about the area's geology and ecology; guided tours typically cost around $10-$20 USD. The waterfall flows primarily during the rainy season (May to October); during the dry season, it may be reduced to a trickle or completely dry. A typical visit lasts 2-3 hours, allowing time for the hike and enjoying the falls. Be sure to wear appropriate footwear and bring water.
