Lake Valencia (Lago de Tacarigua) sits in a closed basin between Valencia and Maracay and was one of the first South American landscapes admired by Humboldt, who travelled here in 1800 and warned that the surrounding deforestation was already lowering the water level. Over the twentieth century the level instead rose, as treated and untreated wastewater from the growing cities of the central valleys was pumped into the basin. The lake is now badly polluted and several historic villages along the shore have been partially submerged.
There is no formal lakeside visitor infrastructure and a beach day here is not an option. What it can be is a short, sobering side-trip — a drive out to one of the partly drowned villages on the southern shore, or a stop at the mirador on the road between Valencia and Maracay — and a vivid case study in how badly central-Venezuelan environmental management has gone wrong over two centuries.
