Iguazu Falls, straddling the border between Argentina and Brazil, is a breathtaking spectacle of nature, comprising hundreds of waterfalls. Accessibility is generally good, with paved paths and elevators at key viewpoints, but some trails involve stairs. While solo exploration is feasible, guided tours offer deeper insights into the local flora, fauna, and history. The falls are impressive year-round, but the rainy season (November-March) brings higher water levels and potentially more dramatic views, though some walkways may be closed due to flooding; the dry season (April-October) offers more predictable weather. Budget travelers can find affordable accommodations and food in Puerto Iguazu, but costs rise for premium experiences. A typical visit lasts 1-3 days to experience both the Argentinian and Brazilian sides, including boat tours and jungle treks.
