Rainbow River, Colombia

The name is something of a giveaway. Okay, the official name is Caño Cristales, but Colombia’s Rainbow River is an incredible celebration of colour that must be seen to be believed. Red, yellow, purple and greens abound in this liquid rainbow, flowing dramatically through the Serranía de la Macarena National Park, with the colours changing depending on light conditions. Red dominates, thanks to the Macarenia clavigera plants on the river’s bed, and the many waterfalls accentuate what is already an incredible sight. รูเล็ตออนไลน์
