The best time to visit Ybycui is during the dry season, which runs from May to September, offering pleasant temperatures and less rainfall.
During these months, the weather is generally mild and sunny, making it ideal for exploring the natural attractions, such as the waterfalls and hiking trails within the Ybycui National Park. You'll find it more comfortable for outdoor activities and wildlife spotting.
For those planning to spend a lot of time outdoors, particularly hiking or enjoying the park's natural pools, May to September provides the most comfortable conditions. The lower humidity also makes for a more enjoyable experience.
If your trip is focused on experiencing the local culture and events, the shoulder months of April and October can also be good.
