A popular summer destination in the western Mediterranean Sea, the main Balearic island of Mallorca combines gorgeous tree-lined hillsides, beautiful Mediterranean seascapes and quaint hillside villages off the beaten track. While this Spanish island is approximately 80 kilometres from one end to the other, it boasts 550 kilometres of coastline, replete with white beaches, rocky coves and limestone cliffs. In the north, pine groves blend into mountain ranges, and the rugged and dramatic western peaks of the Serra de Tramuntana are an official UNESCO World Heritage site. In terms of climate, the hottest months are July and August, whereas the wettest are October and November. In the island's city of Palma de Mallorca, the Enterprise Rent-A-Car branch is near the seafront promenade on Avenida Gabriel Roca. Alternatively, a second branch serves travellers at the nearby international airport.
