투델라‬에서 가장 멋진 ‪19‬개의 천연기념물

One of the most impressive pieces of earth.

There are many beautiful views here. This mountain is the highlight for many.

Castildetierra is a natural formation created by water and wind erosion; a stone placed on top protected the ground below, creating a sort of earth pyramid. The soil has different shades, and at sunrise and sunset it takes on extraordinary reddish hues.

a magical place ... even if it attracts many tourists :)

The 30 km tour is absolutely worth doing...by car or bicycle...scenery that satisfies the eye and the imagination...and in the sky many griffon vultures

Castildetierra is an impressive geological formation located in the Bardenas Reales Natural Park and Biosphere Reserve, in southeastern Navarre. This formation, known as "cabezo," is the result of differential erosion, where the upper layers of more resistant materials, such as limestone and sandstone, protect the lower layers of softer clay. The semi-desert landscape of the Bardenas Reales has been the setting for several film and television productions, including the series "Game of Thrones." There are also several trails to explore the area, with the Castildetierra trail being one of the most accessible and recommended for families.

The Castilla de Tierra, the castle of earth, the brightly colored mountain of sand with a few stones on top is the iconic centerpiece of this impressive park.
