Las Piramides is a shallow Basque Coast slab dive with east-west rock plates, three prominent stones, and a simple profile that feels more like a careful cruise than a big drop-off. The site is built around low relief, crevices, and small-life hunting rather than coral cover or dramatic depth, so the planning feel is about reading the slab line, keeping track of the bottom, and enjoying the micro scenery as you move along the coast. It is a good match for divers who want an easy-to-read local site with plenty of life in a compact area.
