Limestone “gesso” caves near Oulx showcase pale, sculpted gypsum formations and shadowy passageways ideal for moody wide-angle and texture shots. Visit in calmer weather seasons; inside lighting is controlled but dim—plan for slow shutter/low ISO. Entry is typically timed with guided access; bring a jacket and check current tickets/availability.
