The best time to visit Munduapo is during the dry season, which typically runs from late December to March.
During these months, you'll experience more sunshine and lower humidity, making outdoor activities and river excursions much more comfortable. The water levels in the rivers are also generally lower, which can make exploring certain areas by canoe or small boat easier and reveal more of the riverbanks.
For those interested in wildlife spotting, the dry season often concentrates animals around the remaining water sources, increasing your chances of seeing a wide variety of species.
