GR 160 - Camino del Cid BTT: Sierra de Caldereros Loop

This is a difficult mountain bike ride, requiring very good fitness and advanced riding skills. You should be prepared for significant elevation changes and potentially rugged, technical sections where you might need to push your bike. While much of the broader Camino del Cid is less technical, this specific loop is rated as hard.

The trail features significant elevation changes and can be rugged and technical in places. It traverses the Monumento Natural Sierra de Caldereros, offering unique geological formations and natural beauty. You'll encounter a mix of natural spaces, including river lands and areas with ancient fortresses, often in low-population density areas providing a sense of solitude.
