The best time to go to Las Pozas, Petén, Guatemala, is during the dry season, which typically runs from November to May.
During these months, you'll experience consistently sunny weather and lower humidity, making it ideal for exploring the ancient Mayan ruins and enjoying the natural beauty of the region. The trails are drier and easier to navigate, and the rivers are typically at a good level for boat trips. This period also offers clearer skies for photography and stargazing.
For those prioritising comfortable exploration of the archaeological sites, particularly Tikal, the dry season is perfect. You can spend full days wandering among the temples and plazas without the interruption of rain, and the cooler mornings are particularly pleasant for early starts.
Travellers interested in wildlife viewing will also find the dry season beneficial. With less dense foliage, animals like monkeys and various bird species are often easier to spot as they congregate around more limited water sources.
