Ciudad Guayana sits at the confluence of the Orinoco and Caroní rivers in Bolívar state. It is an industrial city — planned and built in the 1960s around heavy manufacturing (steel, aluminum, hydropower) — and is not a destination in itself. Most travelers pass through on the way south toward the Gran Sabana and the Brazilian border, or as a connection point for flights and buses to Ciudad Bolívar.
The natural attractions are the best reason to stop: Parque Cachamay and Parque La Llovizna are both built around impressive rapids and waterfalls on the Caroní River, and the Ecomuseo del Caroní is an unusually thoughtful museum about the river ecosystem and the Pemón people. The Guri Dam on the Caroní, one of the world's largest hydroelectric installations, lies about 100 km upstream — tours have historically been available but may require advance arrangement.
