Cave

For roughly two hours around midday, sunlight enters this small sea cave on the tiny island of Biševo through an underwater opening, reflects off the white limestone floor and floods the entire cave in a glowing electric blue you can hardly believe is natural. It's a short but strictly-controlled boat visit from Komiža on Vis, or a longer speedboat day-tour from Split or Hvar.
