On a short but spectacular path you can explore several lava bubbles. But pay attention, it`s a small path, not recommended for children and people with fear of heights.
Park your car at the "Mirador de Ermita de las Nieves".
From the Ermita go in north direction. In front you will see a stone wall. The footpath started on the left side of the wall . By the way you will see the lava bubbles. On a rocky outcrop, which is formed by the lava flows very striking, is the cache.
Happy hunting
