The coast here is all edges: sharp where the lava froze mid-flow, smoothed only where centuries of waves have rubbed the rock into curves. You park on the dirt shoulder and pick your way down terraced stone, passing through a landscape that looks more lunar than Mediterranean. The water sits dark and heavy against the basalt, surging into crevices, retreating, surging again with the slow breath of the open sea.

You choose your entry point carefully—a flat shelf where the rock dips below the waterline, worn smooth enough that your feet won't shred. The water is shockingly cold for the first thirty seconds, then your skin adjusts and you push off, swimming parallel to the coast where the bottom disappears into blackness. Small fish dart through underwater caves. The visibility is extraordinary: you see twenty, thirty feet down to where the rock face continues its plunge. There's no lifeguard, no boundary buoys, no suggestion that anyone has made this safe for you.
Between swims you sprawl on the hot stone, lizards scattering at your approach, and feel the basalt bake the seawater from your skin. The only shade comes from your own towel, draped over your head. By mid-afternoon the rock is too hot to touch, and you make one final swim before the climb back to the car, legs shaky, head buzzing with sun and salt and the particular satisfaction of having swum somewhere genuinely unforgiving.
