Beautiful setting, impressive waterfall during its bursting season, which is usually in March. And a 700m hike to the highest viewpoint.

The Sierra de Alcaraz is part of the pre-Betic system, a subdivision of the Betic mountain ranges. The predominant vegetation includes reforested pine forests between 1,000 and 1,600 metres, and low scrub near the summit. The most common ascent route is along the south face, starting from the Pino de los Muchachos spring. Although it is not a difficult mountain to access, the climb requires some physical preparation.

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. 🌿🌊

This 40-kilometre-deep cave is the main attraction for many speleologists who visit the park. To visit it, it is necessary to hire the services of an active tourism company in the area or send an application to the Junta de Comunidades de Castilla La Mancha.
