Frequently Asked Questions

What is the overall difficulty of this hiking route?

While the Vía Verde del Cidacos section is generally easy and suitable for various users, the addition of the circular route to the Ajedrezado Caves involves an ascent to an elevated position. This makes the overall difficulty of the hike moderate.

What kind of terrain can I expect on the trail?

The route combines two distinct types of terrain. The main section follows the Vía Verde del Cidacos, which is built on an old railway line, featuring a generally flat surface of asphalt and compacted gravel. However, the circular part leading to the Ajedrezado Caves involves a more varied and ascending path.

Where can I park to access the trail?

You can typically find parking in or around Arnedillo, which serves as a convenient starting point for this circular route. The Vía Verde del Cidacos is accessible from various points, but starting from Arnedillo allows for easy access to both the greenway and the ascent to the caves.

Is this trail dog-friendly?

Yes, the Vía Verde del Cidacos is generally dog-friendly. You can bring your dog along, but please keep them on a leash, especially when passing through populated areas or near wildlife habitats, and remember to clean up after them.

When is the best time of year to hike this route?

The best times to hike this route are typically spring and autumn. During these seasons, the weather is usually mild and pleasant, making for comfortable hiking conditions. You'll also enjoy the vibrant natural scenery, from riverine forests to cultivated lands.

Do I need a permit or pay an entrance fee for this trail or the caves?

No, there are no specific permits or entrance fees required to hike this trail or to visit the Ajedrezado Caves. The Vía Verde del Cidacos is a public path, and the caves are an open archaeological site.

What interesting sights or landmarks will I see along the way?

This route is rich in points of interest. You'll follow the scenic Cidacos Greenway, pass by the Hermitage of San Tirso, and enjoy views from the Gurugus Viewpoint. Don't miss the hot spring pools, the Hermitage of San Andres and San Blas, and the historic Arnedillo Castle. The highlight is undoubtedly the unique Ajedrezado Caves with their distinctive chessboard pattern.

What kind of wildlife can I observe on this hike?

The rocky cliffs along the Cidacos River, especially around Arnedillo, are home to a significant colony of vultures and other rupicolous (rock-dwelling) birds. Keep an eye out for them, particularly from viewpoints. The riverine forests also support diverse birdlife.

Are there any specific regulations or considerations since this trail is within a Biosphere Reserve?

Yes, the trail is located within the Valles del Leza, Jubera, Cidacos y Alhama Biosphere Reserve. While there are no specific entrance fees, please adhere to general responsible tourism guidelines: stay on marked paths, do not disturb wildlife, take all your trash with you, and respect the natural and cultural heritage of the area, especially around the historical caves.

Does this route connect with other trails?

Yes, this route primarily follows and incorporates sections of the Vía Verde del Cidacos. You'll also find it intersects with parts of the Camino Natural Via Verde del rio Cidacos and briefly with the Vía Verde de Préjano, as these are all part of the broader greenway network in the region.

Are there any facilities like restrooms or cafes along the trail?

While the Vía Verde itself is a natural path, you'll find amenities like cafes, restaurants, and restrooms in the towns and villages along the route, particularly in Arnedillo and Santa Eulalia Somera. It's a good idea to plan your stops accordingly, especially before heading up to the Ajedrezado Caves.
