An outdoor rock museum
Before interpreting the wider landscape, it helps to understand its geological building blocks. At La Tejera you will find the ten primary rock types of the Park: slate, quartzite, dacite, conglomerate, sandstone, gypsum, bioclastic limestone, sand, massive limestone, and calcareous tufa.
Each rock features a raw boulder, a cut and polished slab displaying its true colour and grain structure, and a magnifying lens to observe minerals invisible to the naked eye. Interpretive panels explain the topography formed by each rock, its geological age, and traditional building uses.
Very close by
In the surrounding slates lies the Checa graptolite site. A rewarding stop when exploring with families.
