The Jejui Guazú River is one of the most important waterways in central-eastern Paraguay, flowing almost entirely through the San Pedro Department. Formed by the confluence of several smaller streams, it travels approximately 263 kilometers before emptying into the Paraguay River. Its drainage basin is recognized for its biological diversity, encompassing vast wetlands and remnants of the Interior Atlantic Forest. Historically, the river served as a vital artery for transporting yerba mate and timber from the hinterlands to the main ports on the Paraguay River. Today, the Jejui Guazú plays a central role in irrigating surrounding rice paddies and pastures, which form the economic backbone of the region. The river's fish fauna is notable, featuring species such as dorado and surubí, making it a popular destination for recreational fishing. Environmental groups are increasingly active in advocating for the protection of this river system against rising pollution from agricultural runoff and sedimentation.

📋 Practical info
Getting there
The highly photogenic sandy beaches of the river are comfortably reached via local country roads starting from San Pedro del Ycuamandiyú, which frequently lead straight directly into the broadly popular bathing areas.
Best season
The hot summer months extending well into early autumn, specifically from December to April, rapidly attract the most bathing and boating guests to the beaches, even when the daily midday heat becomes highly oppressive.
Terrain & paths
The gently flowing, highly peaceful river is lined by vast, incredibly soft white sandy beaches, which are immediately bordered closely by dense, heavily shade-providing green gallery forests on both banks.
What to bring
Swimwear, large beach towels, highly reliable sun protection, and robust water sandals are totally good; bringing your very own broad sunshade is incredibly practical on the completely unshaded sandy flats.
Parking
Local municipalities and private beach operators almost always reliably provide securely designated sandy parking areas situated immediately adjacent to the widely popular bathing zones, quite frequently for a small fee.
Safety
The calm water appears safe, but bathers should always remain highly vigilant regarding hidden undercurrents and avoid swimming too far from the easily manageable shallow sandy shorelines.
Time needed
For an excursion here, the vast majority of guests happily spend a wonderful half or even a full relaxing day enthusiastically swimming, casually sunbathing, and taking incredibly tranquil boat rides along the scenic shore.
