Early morning departure towards Vis island, which because of its unique geographical position was a strategic harbour for the Yugoslav navy and off-limits to tourists for many years. Vis has retained a rather special charm reflecting the “‘Mediterranean as it once was”. Near Vis, there is a tiny Ravnik island, with the Green Cave interesting to visit (entrance fee not included, to be paid on the spot). It was named after the unusual greenish light that reflects in the sea from the hole on top of the cave. A short swim stop depending on the weather conditions, and then set sail further to the town of Vis for overnight. Vis was developed near the remains of ancient Issa, the first urban centre in Croatia, formed by the Greeks in the 4th century B.C. Visit the remains of the Roman Baths, City Museum, or take a walk enjoying the view of the beautiful Villae Rusticae situated along the coast.
