A few kilometres south of the peak, across from the parador, lies this geological freak show of twisted lava pinnacles with names like the Finger of God and the Cathedral. They are the result of erosion of old volcanic dykes, or vertical streams of magma. The weirdest of the rocks is the Roque Cinchado , while spreading out to the west are the otherworldly bald plains of the Llano de Ucanca.
Note that the Roque Cinchado is wearing away faster at the base than above, and one of these days is destined to topple over (so maybe you shouldn’t get too close). It is such an iconic symbol in Spain that it featured for years on the old 1000 peseta note. This is the most popular spot in the park and is viewed by nearly 90% of its visitors. The car park is always crowded, but most people just leave their cars or tour buses for a 15-minute glance. If you plan to hike the relatively easy, 1½-hour trail that circles the rocks, you’ll most likely be alone.
