Go diving in the crystal clear waters of the Island of Tabarca and look at how the Neptune Grass (posidonia oceanica) moves with the tide while a group of species silently represents life in this marine reserve. Make the most of walking along the city's white streets, designed by the architects of King Carlos III in order to re-house the Genovese population retained on the North-African island of Tabarka by the King of Tunisia in the mid-18th century.
