Even though Mallorca seems to be supercrowded at all times, especially when the cruiseships come in, the island came as a pleasant surprise to me. Palma is a very nice city (and the cathedral would probably be already a WH site if it were in any other country) and the mountains are exceptionally scenic, sometimes even spectacular. The Serra de Tramuntana range is the spine of the island (and protects the beaches from the northern winds) and reaches a height of over 1,400 metres. It includes several pretty towns and various monasteries, including the huge one at Lluc. Even though it is not really easy to find out where the core zone of the WHS starts and what is only in the buffer zone, you can be reasonably sure that any trip to the northern coast will make you traverse the core zone. The site is inscribed as a cultural landscape, and it is quite easy to make out various aspects of this as you make your way through the mountains, especially the historic stone walls separating the fields, some of which date back to Arab times. I did two trips to the mountains, both of them very much on the tourist trail and likely to be offered by various agencies - the half-day trip to Valldemossa to visit the Charterhouse (of Chopin and Sand fame) and the full-day trip to Sa Calobra (very winding roads and extraordinarily scenic), followed by a boat ride to Port de Sóller, a tram ride to Sóller, and a train ride back to Palma.
