The best time to visit El Retorno, Guaviare, is during the dry season, which typically runs from December to March.
During these months, the weather is generally sunny with less rainfall, making it ideal for exploring the region's natural attractions. The roads are also more accessible, which is a significant advantage when travelling to sites like the Cerro Azul and Nuevo Tolima caves or the various rock art sites. This period offers the most comfortable conditions for outdoor activities such as hiking, birdwatching, and river excursions.
For those interested in exploring the unique geological formations and ancient rock art, the dry season ensures clearer paths and better visibility. The lower water levels in the rivers also make boat trips more predictable and enjoyable. This is particularly appealing for travellers who appreciate unhindered access to remote natural wonders and archaeological sites.
While the dry season is generally preferred, some travellers might consider the shoulder months of November and April. During these times, you might experience occasional showers, but the landscapes are often lusher, and there are fewer visitors, offering a more tranquil experience.
