Orto Botanico
Located just below Cagliari's amphitheater, the city's Botanical Garden offers a welcome refuge from the summer's heat, and a shady spot for a pause from sightseeing. The 12-acre site is managed by Cagliari university and includes plants from all over the Mediterranean as well as Africa and further afield, plus herbariums, ponds, and a scattering of Roman remains, notably cisterns, tanks, and a well. As the only green space in the city center, it's ideal for kids to let off steam, and perfect for a picnic. Guided tours are also available (book ahead).
