Grotta Azzurra (Blue Grotto) is a sea cave where sunlight turns the water intense electric blue. Photographers shoot the glowing water, boat-lit cave entrances, and shimmering reflections. Best light is mid-morning to early afternoon on clear days; crowds build in peak summer. Access is by short boat rides from nearby harbors—book/arrive early. Bring a light jacket; splashy spray and spray haze are common.
