Platja del Port Blanc is a small cove on the Puerto Blanco side of Calpe, sheltered by the marina works and made of sand, gravel, and clear Mediterranean water. It is not the town's broad beach scene; it is a compact alternative when you want a more tucked-away swim.
The beach is useful for combining sun, a short coastal wander, and diving or snorkelling plans around the old port area. Check local conditions before committing, because small coves change character quickly with works, seaweed, and summer pressure.
