This guidebook presents 50 half-day and day walks in Mallorca's Serra de Tramuntana, the striking limestone range that stretches along the northwestern flank of the island. Whilst the region promises breathtaking scenery and some fantastic walks, there is also some potentially challenging terrain, making guidance when choosing, planning and walking the routes all the more valuable. As many involve steep ground, navigational challenge and hands-on scrambling, these routes are primarily geared towards those with some experience of mountain walking. Comprehensive route description is illustrated with 1:25,000 Alpina mapping and each walk includes a statistics box to aid route selection. Useful contacts are listed in the appendix. There is also background information on history, plants and wildlife, plus language notes in native Catalan and Castilian Spanish. The routes are spread across the Serra de Tramuntana, with characterful towns and villages such as Sóller, Deià, Fornalutx, Valldemossa and Pollença serving as potential bases for a walking holiday. Ranging from 5.5km to 24km, the carefully selected routes showcase the region's rugged limestone peaks, mountain and coastal vistas and rich mountain heritage manifested in numerous drystone constructions, charcoal-burning sites and irrigation systems. Highlights include the lush island of sa Dragonera and the dramatic gorge of Torrent de Pareis. The majority of walks are accessible by public transport and many can be linked, opening up further possibilities for exploration.
