It's no wonder that the start of the Mundo River, in the Spanish town of Riopar, is considered to be among the most beautiful river sources in all the world. The 93-mile-long body of water originates from a cave that sits in the middle of a cliff, the cascading stream forming a waterfall over 300 feet high that descends into smaller spouts and pools. As if the town's picturesque setting wasn't already reason enough to visit.
