The best time to visit Mariscal Estigarribia is during the dry season, which runs from May to September.
During these months, the weather is more pleasant, with cooler temperatures and significantly less rainfall, making it ideal for exploring the Chaco region. This period is also better for wildlife spotting, as animals often gather around the more limited water sources.
For those interested in birdwatching or nature photography, the dry season offers clearer skies and better visibility.
