Weather…

The Guaviare River is a major waterway in eastern Colombia, formed by the confluence of the Guayabero and Ariari rivers. It flows eastward to eventually join the Orinoco, acting as a natural transition zone between the expansive Llanos plains and the Amazon rainforest. The river is ecologically significant as it links two distinct biomes and functions as a biological corridor for various wildlife species. Historically, the Guaviare region was deeply affected by armed conflict, which restricted scientific study and tourism for decades. In recent years, the river has emerged as a destination for ecotourism, notably for those visiting the ancient rock paintings of Cerro Azul near San José del Guaviare. While the river's waters are rich in fish and support local livelihoods, the Guaviare faces environmental pressures from land-use changes and deforestation within its catchment area.
