The best time to go to Tantara is during the dry season, which runs from May to October.During these months, you'll experience clear skies and pleasant temperatures, making it ideal for exploring the region's stunning natural landscapes and ancient sites. The days are generally sunny, with average temperatures hovering around 20-25°C, while evenings can be cooler, so a light jacket is advisable. This period is superb for outdoor activities like hiking to the nearby waterfalls or visiting the archaeological ruins scattered around the area.For those planning to attend the annual Festival of the Water (Fiesta del Agua), which is a significant cultural event in the region, visiting in late June or early July would be ideal. This festival offers a unique insight into local traditions and is a truly memorable experience. However, accommodation can book up quickly during this time, so it's wise to plan well in advance.Avoiding the rainy season, from November to April, is recommended as heavy rainfall can make travel difficult, and some roads may become inaccessible.
