The birth of the Mundo River is an amazing natural phenomenon located in the province of Albacete, in Spain. This river emerges with great pressure from a network of underground galleries and caves, emerging in the form of a siphon from the Cueva de los Chorros. From there, it falls into a waterfall more than 100 meters high, forming several small waterfalls along the way. If you ever have the opportunity, I recommend visiting this unique corner of La Mancha and enjoying the majesty of the source of the Mundo River. 🌿🌊
