Early in the morning, cruise toward the little island of Biševo to visit the Blue Cave, a magnificent natural phenomenon. The visit depends on sea conditions; entrance tickets are paid on the spot. After the cave, continue toward the island of Vis, once a strategic harbour for the Yugoslav navy and closed to the public for decades. Thanks to that isolation, Vis kept the rare charm of “the Mediterranean as it once was.” Overnight will be in Vis or Komiža (depending on berth availability). Vis sits on the northern side of the island, developed near the remains of ancient Issa, the first urban centre in Croatia. If you feel like exploring, visit the Roman Thermal Baths and the City Museum, or enjoy a walk along the waterfront with views of the villae rusticae scattered along the shore. For travellers who want to see more, renting a car or scooter is an easy way to discover the rest of this surprisingly wild island.
