Caño Cristales, Colombia
You’ve probably heard of Bogota, Colombia, but you may not have heard of the river Caño Cristales. There are numerous undiscovered places in Colombia, and that’s one of them. Seriously, it’s so spectacular it should be considered the eighth wonder of the world. This is where you’ll find waterfalls and rare local flora you’ll only see here. For half of the year, Caño Cristales takes on a vibrant beautiful yellow, green, red, and black color. This is because of the ‘macarenia clavigeria’ phenomenon, which is a plant. This plant has magic powers because it turns an entire river into a rainbow wonderland (via Hostelworld).
