Camping Municipal El 300 is a campground situated along the Arroyo Aguaray Guazú, near Ruta Nacional N°12 in the province of Misiones, Argentina.

The arroyo itself is a clear, winding waterway that flows through lush native vegetation, including species such as Loro negro, Lapacho, and Guatambú, interwoven with climbing plants and epiphytes.

The surrounding environment supports a rich variety of wildlife, with birds such as toucans, hummingbirds, and parrots, as well as fish, reptiles, and amphibians inhabiting the stream and its banks.

The crystalline waters of the Aguaray Guazú provide a refreshing natural setting for campers looking to enjoy the biodiversity characteristic of the Misiones region.
