On the northern coast of Lanzarote, along the road that runs through Haría, you'll find the Piscina Natural Las Rosas, a volcanic formation shaped by the sea over time. It's a set of natural pools protected by dark basalt rocks, where Atlantic water enters and renews with the tides.

Access is from the main road, and the surroundings preserve the volcanic landscape characteristic of this part of the island. Swimming conditions depend directly on the sea state and tides: when the swell is strong or the tide is high, the pools may be covered or rough. The rocky formation offers natural shelter from the open ocean, though you should check sea conditions beforehand when planning your visit.
