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

There is an impressive abyss in front of us (be careful if you feel dizzy) and another stone needle rises below us, and to our left is the reservoir. Spectacular.

Magical place both by extraordinary rock formations, by the magnificent view and the feeling of being suspended above the void. Access to the edge of the cliffs is relatively easy, and of course great care is necessary because the surroundings are not protected.

The entire "Carretera de Chóvar-Eslida" is a beautiful mountain road that is very worthwhile in both directions. On the Eslida side it is mostly shady, certainly enjoyable in summer, cold in winter even in sunny weather! From or to Eslida you can go towards the sea or further into the Serra Espada, which is really spectacular there at Ain! Everything that is marked in yellow by Komoot here are roads of the finest racing bike quality, on which you can really let it rip. But the landscape is actually too beautiful for that!

Rising above 1,000 meters above sea level, it is the highest point in the Parc Natural de la Serra d'Espadà. It offers amazing views in all directions and without a doubt getting there is quite a challenge. It is a place very visited by hikers and runners who aspire to reach the top beyond 1000 meters above sea level. Be careful on the way because by sectors it can be somewhat technical and rocky.

Sierra Espadà is renowned for its Triassic geological formations, particularly the reddish silicic sandstones known as "rodé." These, combined with grayish limestone, create a striking polychromatic landscape. You'll encounter abrupt peaks, deep ravines, and unique rock structures like the Órganos de Benitandús, which resemble a pipe organ.
For breathtaking panoramic views, consider hiking to Espadán Peak, the highest point in the natural park. From here, you can see in all directions. The Órganos de Benitandús also offer magnificent views, providing a sense of being suspended above the void with vistas of the Onda reservoir.
Yes, the Ajuez Reservoir, also known as Balsa de Chovar, is a very quiet place surrounded by nature, making it an ideal spot for families to relax and enjoy the environment. While some natural monuments involve more challenging hikes, many areas within the cork oak forests offer tranquil paths suitable for family walks.
The difficulty varies. For instance, reaching Espadán Peak is considered quite a challenge, with sectors that can be technical and rocky. The path to Órganos de Benitandús also requires a firm step due to some technical sections. However, there are also easier routes, such as those found in the cork oak forests or around the Ajuez Reservoir.
Sierra Espadà offers a wide range of outdoor activities. You can explore numerous hiking trails, from easy hikes to more challenging ascents. The region is also a popular destination for cycling, with beautiful mountain passes like Eslida Pass and Coll d’Aín, making it a cycling paradise. Gravel biking is also popular, with many routes available.
The cork oak forests provide shade, making them enjoyable even in summer, though they can be cold in winter. Generally, spring and autumn offer the most pleasant temperatures for hiking and exploring the natural monuments, avoiding the peak heat of summer and potential chill of winter.
Sierra Espadà hosts one of the few sandstone outcrops in this part of Spain, which, combined with higher rainfall, allows cork oak trees (Quercus suber) to thrive. These extensive forests are unique to the region, providing critical habitats for diverse wildlife, including various bird species like the Bonelli's eagle, foxes, and wild boars. They offer tranquil trails for hiking and wildlife spotting.
Absolutely. Eslida Pass is considered one of the most beautiful mountain passes in the region, offering scenic views and a rewarding experience for cyclists and hikers. Another picturesque option is Coll d’Aín, known for its spectacular setting and minimal traffic, ideal for tranquil routes.
Given the varied terrain, which can include technical and rocky sectors, it's advisable to wear sturdy hiking boots with good ankle support. Layered clothing is recommended to adapt to changing temperatures, especially if you're ascending to higher points like Espadán Peak. Don't forget sun protection and plenty of water.
Visitors frequently praise the extraordinary rock formations, the magnificent panoramic views from various viewpoints, and the feeling of being immersed in a unique natural environment. The challenge of reaching summits like Espadán Peak and the tranquility of the cork oak forests are also highly appreciated.
Public transport options directly to individual natural monuments within Sierra Espadà are generally limited. It is often recommended to travel by car to access trailheads and specific sites. However, local buses might connect larger towns surrounding the park, from which you could potentially start your exploration.
While the focus is on natural features, the region has a rich history. For example, the Ajuez Reservoir was built in the 12th century by Muslims for irrigation, highlighting the historical importance of water management. The cork oak forests also have historical significance, with an exhibition on cork in the interpretation center in Eslida village.
