A beautiful spot between Artana and Onda that is worth visiting. The path is in good condition and runs through beautiful forests with the Peñas Altas in the background.

On the previous climb, there is a moment where you have to go over a cable with a no entry sign, but that is because there are bee hives, they are quite far from the path.

It was built in the 12th century by the Muslims who inhabited the region. Its original purpose was to retain the waters of the ravine of the same name and then use them to irrigate the fields downstream. This route is ideal for hiking lovers and offers a variety of landscapes and experiences. I hope you enjoy exploring the Ajuez Reservoir and its surroundings! 🌿🏞️

Ernbalse de Ajuez Unfortunately, the reservoir is almost dry and things are slowly getting tight for the fish and turtles. The Chóvar Reservoir, as it is also called, is part of an ancient local irrigation system built to retain the rushing water from the eponymous gorge. The place name is derived from Arabic, the meaning of which means “common pastureland” and indicates the importance of agriculture and livestock breeding in the region. Due to its capacity of 30,000 m³ and the lack of water sources in the nature park, it is of great value for the fauna. It is currently included in the catalog of wetlands of the Valencian Community

The path leads us along the red rocks to the Pic de la Font de Cabres. Sure-footedness and a head for heights are required.

Nice place to disconnect. From the top there are impressive views, although to go up you have to be moderately prepared (and not have vertigo). A place worth visiting, both from the viewpoint below and from the rocky ledges at the top.

You'll find lush cork oak forests, numerous freshwater springs, and fresh ravines. Notable geological formations include the red sandstone formations of Peñas Aragonesas, and impressive mountain passes like Eslida Pass. The area also features tranquil water bodies such as the Sichar Reservoir and the Ajuez Reservoir.
While popular spots like Eslida Pass and Espadán Peak are well-known, the Peñas Aragonesas offer a unique and picturesque geological point with striking red sandstone formations that are highly appreciated by visitors. Another less-trafficked spot is the Ajuez Reservoir, also known as Balsa de Chovar, which provides a very quiet natural environment just a short distance from the town of Chovar.
The natural monuments around Onda are ideal for various outdoor activities. The Sierra de Espadán Natural Park offers an extensive network of hiking and cycling trails. You can find numerous routes for mountain biking, touring bicycles, and road cycling. For example, explore the 'Natural Park of Serra d'Espada' on a challenging road cycling route, or try the 'Sichar Reservoir – Embalse de Sitjar loop' for mountain biking. You can find more details on these activities and routes in the MTB Trails around Onda, Cycling around Onda, and Road Cycling Routes around Onda guides.
Yes, the region offers options for families. The Ajuez Reservoir is considered a family-friendly spot, ideal for a quiet escape into nature. The Sichar Reservoir also has a recreational area with tables, benches, and barbecues, perfect for a day out with the family. While some trails in the Sierra de Espadán can be challenging, there are also easier paths suitable for family walks.
The Sierra de Espadán Natural Park, where many natural monuments are located, is beautiful throughout the year. However, for hiking and outdoor activities, spring and autumn generally offer the most pleasant weather with milder temperatures. Summers can be hot, but shaded areas, like the Eslida side of Eslida Pass, can be enjoyable. Winters can be cold, especially in higher elevations.
Yes, the region blends natural beauty with historical significance. The Sierra de Espadán Natural Park itself contains numerous remains of castles built by the Arabs. Additionally, the Cova de l'Algepsar, located at the foot of Onda Castle, is a man-made cave that served as a refuge during the Spanish Civil War. While not purely natural, its historical role within the natural setting makes it a compelling visit.
Given the varied terrain, from mountain passes to forested trails, it's advisable to wear comfortable hiking shoes with good grip. Layers of clothing are recommended, especially if you plan to ascend to higher points like Espadán Peak, where conditions can change. Sun protection, including a hat and sunscreen, is also important, particularly during sunnier months.
Generally, dogs are permitted on many trails within the Sierra de Espadán Natural Park, but it's always recommended to keep them on a leash to protect wildlife and ensure the safety of other visitors. Specific rules may apply in certain protected areas or near water sources, so it's best to check local signage or park regulations.
Access to the Sierra de Espadán Natural Park and its natural monuments is primarily by car, with various parking areas available near trailheads and key attractions. Public transport options directly to the more remote natural monuments might be limited. Onda itself is accessible by public transport, and from there, local taxis or personal vehicles would be the most convenient way to reach specific sites within the park.
For expansive views, Espadán Peak is the highest point in the Parc Natural de la Serra d'Espadà, offering amazing views in all directions from almost 1,100 meters above sea level. Another excellent viewpoint is Pic de la Font de Cabres, which provides impressive panoramic views of the coast, the valleys of the Plana Baixa, and even the province of Valencia from its 570 meters.
The Sierra de Espadán Natural Park is rich in biodiversity, offering opportunities for wildlife spotting. The lush cork oak forests and fresh ravines provide habitats for various bird species, reptiles, and mammals. Keep an eye out for local fauna while exploring the trails, particularly in quieter areas away from main routes.
The time required varies greatly depending on the monument and your activity. A visit to a specific highlight like Peñas Aragonesas or the Ajuez Reservoir might take a few hours. For extensive hikes to summits like Espadán Peak or exploring the full length of Eslida Pass, you should plan for a half to a full day. To truly experience the diversity of the Sierra de Espadán, multiple days are recommended.
