Las Tuerces, Nature reserve in Aguilar de Campoo, Spain.
Las Tuerces is a nature reserve featuring limestone formations with stone pillars, natural bridges, and passages carved between large rock blocks. The landscape spans a considerable area and allows visitors to walk through these geological structures.
The area was home to an Iberian settlement, with remains found on Monte Cildá, followed by Roman fortress structures. These archaeological layers show multiple periods of human occupation.
The rock-carved hermitage of Saints Justus and Pastor near the reserve reveals medieval religious practices in the region. Visitors can observe the crafted details and setting of this chapel, which is built directly into the natural rock.
Marked hiking trails connect different sections of the reserve and allow visitors to explore at their own pace. The area is accessible year-round and offers routes suitable for different fitness levels.
The reserve provides habitat for rare animal species such as the Pyrenean desman and the Eurasian otter, found in few other European locations. The diversity of natural habitats makes this region an important refuge for endangered species.
