Jaén offers a landscape defined by sixty-six million olive trees and some of the most challenging mountain terrain in the Iberian Peninsula. Whether you prefer the flat gravel of a converted railway or the steep, limestone crags of the Sierras, this province provides space that more famous coastal routes cannot match.

While many cyclists head straight for the climbs of the Sierra Nevada or the rolling hills of the Algarve, Jaén remains a destination for those who value quiet roads and untouched trails. The province is roughly divided into two distinct experiences: the vast, rolling seas of olive trees that occupy the central plains and the dramatic, high-altitude wilderness of the Sierras de Cazorla, Segura y Las Villas and Sierra Mágina. It is a place where you can spend four hours on a road bike and encounter more eagles than cars.

The infrastructure for cycling in Jaén has improved significantly over the last decade. The development of the Vía Verde network has opened up the province to families and casual tourers, while the mountain biking centres (Centros BTT) have mapped out technical routes for experienced riders. The local culture is deeply intertwined with the outdoors; you will find that even the smallest village bar is used to seeing groups of cyclists leaning their bikes against the whitewashed walls while they stop for a coffee or a glass of local olive oil on toast. This guide explores the best ways to experience the province on two wheels, whether you are looking for a gentle afternoon ride or a multi-day endurance challenge.

The Vía Verde del Aceite: The Olive Oil Greenway

The Classic Route from Jaén City to Alcaudete

The Vía Verde del Aceite is the longest greenway in Andalucía, stretching for 128 kilometres between Jaén and Puente Genil in Córdoba. For those staying in the provincial capital, the first 55-kilometre section to Alcaudete is the most accessible. Following the track of the old "Tren del Aceite" (Oil Train), the route is almost entirely flat or very gently graded, making it suitable for hybrid bikes and families.

One of the highlights of this section is the series of nineteenth-century metal viaducts designed by disciples of Gustave Eiffel. Crossing the Guadajoz River or the various deep ravines provides incredible views over the silver-green canopy of the olive groves. The track is well-surfaced with compacted gravel and is separated from motorised traffic. In Martos, roughly 24 kilometres from the start, you can stop at the old station, which has been converted into a cafe and information point. Expect to pay around €25 per day for a standard mountain bike hire or €45 for an e-bike from local shops like Ciclos Luna in the city centre.

Extending the Journey into Subbética

If you have more than one day, continue past Alcaudete towards the border with Córdoba. The landscape becomes more rugged as the route skirts the edges of the Sierras Subbéticas Natural Park. The Guadajoz viaduct is the most spectacular point here, marking the boundary between the two provinces. For those doing the full 128km, there are several accommodation options specifically geared towards cyclists, such as the refurbished station buildings or small rural guesthouses that provide secure bike storage. Most local taxi companies in Jaén and Alcaudete offer a shuttle service to bring you back to your starting point for around €60-€80 depending on the number of bikes.

Mountain Biking in the Sierras de Cazorla, Segura y Las Villas

The Borosa River Trail

Cazorla is the largest protected natural area in Spain and a primary destination for mountain bikers. One of the most famous routes follows the Borosa River. While the lower sections are accessible to most, the climb towards the Laguna de Valdeazores is a test of stamina. You will ride through deep limestone canyons and past waterfalls like the Salto de los Órganos. [AFFILIATE: Guided MTB tour in Cazorla]

The terrain here is varied, featuring forest tracks, rocky singletrack, and some steep technical descents. It is essential to carry a GPS or a detailed map, as the network of forestry tracks is vast and poorly signposted in certain areas. Operators like Centro de Turismo Ecuestre y Actividades en la Naturaleza in Arroyo Frío offer high-quality MTB rentals and guided excursions. A full-day guided tour typically costs between €50 and €70 per person, including the bike and helmet.

Ascending El Yelmo

For those in the Segura section of the park, the climb to the summit of El Yelmo (1,809 metres) is the definitive challenge. Starting from the village of Segura de la Sierra, the route takes you up a winding paved and gravel track to a peak that offers views across the entire province and into Castilla-La Mancha. The descent back down to Cortijos Nuevos is fast and requires good braking control. This area is much quieter than the southern Cazorla hub, offering a more solitary experience for those who want to escape the crowds.

Road Cycling: Despeñaperros and Sierra Mágina

The Despeñaperros Mountain Pass

Historically the only gateway into Andalucía from the north, Despeñaperros is now bypassed by a modern motorway, leaving the old N-IV road almost entirely to cyclists and local traffic. This is a dream for road cyclists. The road winds through dramatic orange-hued cliffs and dense Mediterranean forest. The gradients are manageable, rarely exceeding 6 or 7%, but the sheer number of curves makes it a technical and engaging ride. Starting from Santa Elena, you can complete a circular route that takes in the Roman ruins of Castulo and the town of La Carolina.

The High Peaks of Sierra Mágina

Sierra Mágina is often overlooked in favour of Cazorla, but for serious road cyclists, it offers some of the toughest climbs in the region. The ascent to the village of Bélmez de la Moraleda and the surrounding high mountain passes provide steep gradients that have frequently been featured in the Vuelta a España. The air is thinner here, and the scenery is starker, with high-altitude karst landscapes replacing the olive trees. Be prepared for rapid weather changes in this area, even during the spring months.

Practical Information

Cycling in Jaén is best enjoyed during the spring (March to June) and autumn (September to November). July and August should be avoided due to extreme temperatures which frequently exceed 40°C in the valleys. During the winter, the high mountains of Cazorla and Mágina often see snow, though the Vía Verde remains rideable and often very pleasant in the midday sun.

Bike hire is concentrated in Jaén city, Úbeda, and the tourist hubs of Cazorla (specifically Arroyo Frío). Prices for a standard hardtail mountain bike range from €20 to €30 per day. E-MTBs are increasingly popular given the vertical nature of the province and usually cost around €50 per day. Always carry a repair kit; while towns are frequent in the olive-growing areas, you can be very isolated in the Sierras. Water is also a priority; although there are mountain springs, you should carry at least two litres for any ride over two hours. Most local trains (Media Distancia) allow bikes, but you must book a space in advance, as capacity is limited to three bikes per train.

Local Tips

The best way to refuel in Jaén is to take advantage of the local tapas culture. Unlike many other parts of Spain, when you order a drink in a village bar in Jaén, a substantial tapa is provided for free. Look for "andarijos"—a local term for hikers and cyclists—at weekend morning spots. Also, keep an eye out for the "Coto de Caza" signs in the autumn; if you are mountain biking in the Sierras during hunting season (October to February), it is wise to stick to the main signposted tracks and wear bright clothing.
