Hedonistic and historic, Eivissa (Ibiza, in Castilian) is a city jam-packed with cafés, nightspots, and trendy shops; looming over it are the massive stone walls of Dalt Vila —the medieval city declared a UNESCO World Heritage site in 1999—and its Gothic cathedral. Squeezed between the north walls of the old city and the harbor is Sa Penya, a long labyrinth of stone-paved streets that offer some of the city's best offbeat shopping, snacking, and exploring. The tourist information office on Vara de Rey has a useful map of walks through the old city.
