Grotta Azzurra (Blue Grotto) is a sea cave off Terrasini, famous for the vivid turquoise light that floods the water surface. Photographers should chase the glowing rock walls and mirror-like reflections at boat level, with cave-entry framing for dramatic color contrast. Summer crowds can be heavy; go early morning for calmer seas and cleaner light.
