Caño Cristales, Colombia
For many people, Colombia feels like an unexplored corner of South America, reserved for the intrepid. But since the 2016 peace agreement, tourists have converged on Caño Cristales, Responsible Travel says.
“Known as the ‘River of Five Colors,’ a waving undercurrent of aquatic plants turn the water yellow, pink, and even red,” Francis explained.
Around 16,000 people visit annually, but even this small number is enough to threaten the delicate environment, Francis says. In December 2018, the river was closed to allow it some recovery time. It reopened in July 2019.
