Located from El Haouaria and from the port of La Goulette, it is a natural extension of the peninsula of Cap Bon. Zembra is a natural fortress that housed a resort until 1976 and then passed into the hands of the Tunisian army. On the southern coast there are remains of an ancient harbour. Zembra is most probably the same as the island called Aegimouros () by many ancient writers. Pliny the Elder called  both Zembra and Zembretta Aegimuri. Environment. Zembra has a fragile ecosystem and has been classified as a protected area by UNESCO since 1977. The island has a Mediterranean climate. The native soils include rock, clay, sand and magnesium lime. Flora and fauna. The island's vegetation consists of about 266 plant species; the flora is characterised by a canopy of dense bush, including olive, Phoenician juniper and gorse, and the presence of rare plants which favour saline soils. There are also invertebrates and terrestrial mammals introduced by man, such as rabbit, , black rat and feral cat. Dolphins are also common  in the waters surrounding the island. In addition, Zembra is located on an avian migration route between Tunisia and the Strait of Sicily, and hosts more than 25,000 pairs of migrating birds which nest in the rocky cliffs; the island is home to the largest colony of Scopoli's shearwaters in the Mediterranean. The island, along with the neighbouring islet of Zembretta, has been designated an Important Bird Area (IBA) by BirdLife International.
