The Monday River is a major tributary of the Paraná River, forming these falls just kilometers before their confluence.
The basalt rock formations at the site are characteristic of the massive volcanic activity that formed the Paraná Plateau millions of years ago.
The surrounding municipal park is part of a larger effort to preserve the Atlantic Forest corridor in the Alto Paraná region.
The waterfall's name is derived from the Guaraní word 'monda', often translated as 'to steal' or 'to trap', referring to the powerful currents of the river.
Monday Falls (Saltos del Monday) is a 45-meter-high waterfall situated within a protected municipal park in Presidente Franco, Paraguay. The falls consist of three primary cascades that plunge into the Monday River canyon. The park area serves as a transition zone between the Upper Paraná Atlantic Forest and the river ecosystem. Visitors access the falls via a series of trails and viewing platforms constructed along the cliffside. The site features a combination of native forest trails, adventure sports infrastructure, and proximity to the confluence of the Monday and Paraná rivers. It operates as a municipal facility focusing on conservation and tourism.
The main viewing platform located directly across from the central cascade.
Wear footwear with high-traction soles as the paths near the canyon rim can be slick from mist.
Bring insect repellent, as the humid, forested environment often hosts high mosquito activity.
Utilize the designated observation decks for the safest views of the main drop.
