Falla de la Sierra del Camorro

Falla de la Sierra del Camorro is a geological fault and natural monument in the municipality of Cuevas de San Marcos, in the province of Málaga, set at the foot of the Sierra del Camorro massif. It is a place where two blocks of the earth's crust have shifted against one another, creating one of the clearest visible examples of this process in Andalusia — and, alongside it, a raw, rocky landscape that draws hikers and climbers looking for something different from the Costa del Sol's beaches.

What can you see there?

The main draw is the fault itself — a limestone wall where the displacement between rock layers is visible to the naked eye. The massif is built from nodular limestones, dolomites and marly limestones dating to the Lower and Middle Jurassic, which explains both its hardness and its resistance to erosion, as well as the rich karst features carved into it over time. Near-vertical ridgelines, numerous cavities, fissures and chambers holding underground lakes are the result of thousands of years of water working on limestone rock.

The best-known underground feature is Belda Cave, a passage roughly 250 metres long where water accumulates permanently, forming internal pools. It is also home to a protected bat colony, which is why unguided access to the interior is generally discouraged outside organised trips. Traces of settlement dating back to prehistoric times have been found on the surrounding slopes and in nearby caves — people occupied this ground long before the present-day village existed.

The highest point of the whole massif is Cuevas Altas (907 metres), a geodetic survey point and a natural target for anyone planning a full day out in the mountains.

How do you get there and explore it?

Most routes start near the "Senda de los Milenios" interpretation centre in Cuevas de San Marcos, close to the town's football pitch. From there, the marked PR-A-234 trail runs through the Camorro massif toward the fault and the ridge above it. The route covers roughly 7.5 km with about 560 metres of elevation gain, and typically takes around 5 hours there and back — a moderate-to-demanding hike, with some sections that call for extra care on steep, rocky ground.

The area also draws climbers: rock routes have been set up around Cuevas de San Marcos, making it a regular destination for hiking and climbing clubs from across the Málaga region.

Sturdy hiking boots, long trousers to protect against scrub and sharp rock, sun protection, a hat, and enough water and food are essential — the nearest supplies are back in the village itself.

When is the best time to visit?

Because the approach is exposed and rocky with little shade for most of its length, spring (March to June) and autumn (September to November) are the best windows to visit, when inland temperatures in Málaga province are manageable for several hours of walking. Summer heat in this part of the province can be severe, while winter's shorter daylight hours limit the time available for a safe return — if you do go outside those seasons, start early in the morning.

Frequently asked questions

Can you enter Belda Cave on your own? Given the protected bat colony inside and the difficult terrain, it is best visited as part of an organised trip with a local guide or hiking club rather than on your own.

How long does the full route take? The full loop along the PR-A-234 trail through the Camorro massif takes around 5 hours, including the approach to the fault, the climb toward Cuevas Altas, and the return to the starting point.

Is the route suitable for beginners? The trail is moderate to demanding — it requires reasonable fitness, proper footwear and care on steep, rocky sections, so it is not the best choice for a first mountain hike.

Is climbing available in the area? Yes, rock climbing routes have been established around Cuevas de San Marcos on the massif's limestone walls, and they are popular with climbers from the Málaga region.
