Castillo del Peñón de Inox

Castillo del Peñón de Inox is a ruined medieval castle in the municipality of Níjar, in the province of Almería, within the Cabo de Gata-Níjar Natural Park in Andalusia, Spain. The fortification sits on a rocky outcrop at the foot of the Sierra Alhamilla mountains, near the Colativí peak, at an altitude of roughly 650 metres above sea level, a few kilometres west of Níjar itself, close to the small hamlet of Inox.

What is this place?

The castle was built during the Nasrid period, when the Almería region was still under Muslim rule, and it served to defend and control the mountainous hinterland behind the Cabo de Gata coastline. Its most significant historical episode came later, after the Christian conquest, during the Morisco Rebellion of 1568–1570. During the so-called Christmas riots of 1568, Morisco families from across the Níjar region took refuge at the Peñón de Inox castle while awaiting the chance to cross to the North African coast. The site is therefore a witness to one of the most dramatic chapters in the history of Andalusia's Morisco population, which ended with their expulsion from Spain.

Today only scattered traces of walls and foundation outlines survive — the castle itself has largely been lost to erosion and time. Despite this, Castillo del Peñón de Inox has been officially listed as a Bien de Interés Cultural (a nationally protected Cultural Heritage asset) in the Monument category, recognising its historical value to the region.

How do you get there?

The ruins lie inland, in the hill country north of the Cabo de Gata coastal strip, near the small settlement of Inox, west of Níjar. Access to the site is free and unrestricted, but because of the rocky, elevated terrain reaching the ruins requires a walk on foot — it makes sense to plan the visit as part of a hiking or cycling route through the Sierra Alhamilla foothills and the town of Níjar.

What will you see?

Visitors will find the scattered remains of old defensive walls set into a rugged, rocky landscape, and above all sweeping views over the Sierra Alhamilla hills and the valley toward Níjar. This is a site for those interested in the military and Moorish-era heritage of Almería rather than a polished, well-preserved monument — its appeal lies mainly in its historical background and the surrounding scenery.

When should you visit?

Given the lack of visitor infrastructure and the rocky approach on foot, spring and autumn are the best times to visit, when temperatures are milder than in the height of summer. Morning hours help you avoid the heat typical of this, one of the driest corners of Spain.
