Coursing down the steep slopes of the Andes, the Pastaza River meets the edge of the Amazon jungle when it's forced through a narrow channel that concentrates the river's power like a firehose. The roiling torrent then shoots over the edge of this mountainside, plunging 200 feet into a cauldron-shaped pool. Agoyán, better known as El Pailón del Diablo (The Devil's Cauldron), is Ecuador's tallest and most famous waterfall. It's a highlight of the Ruta de las Cascadas (Route of the Waterfalls), a popular circuit of the many waterfalls and hot springs near the mountain town of Baños de Agua Santa.
