as it traverses the rocky peaks of the Serra de Tramuntana. Following old stone-paved paths and mule trails, it showcases the region's beautiful landscape of mountains, forests and cultivated terraces, as well as its spectacular coastline. The GR221 can be walked in 1-2 weeks, although the guide also covers 3 alternative start-points and 3 alternative finishes, which would allow for a shorter trek. The main route is presented in 10 stages of 8.5-20.5km (5-13 miles), with a handful of optional detours to bag neighbouring summits. Detailed route description is accompanied by 1:25,000 mapping and inspirational photography, plus a wealth of information on local points of interest. Accommodation and travel are also thoroughly covered: the trail boasts good transport links and plentiful facilities on route, with accommodation in welcoming mountain villages and the occasional 'refugi'. A comprehensive introduction offers the opportunity to discover more about the region's diverse plants and wildlife and unique history and culture, and an English-Spanish-Catalan glossary can be found in the appendix. With a favourable climate and stunning scenery, the Serra de Tramuntana has much to tempt the walker. The GR221 Drystone Route represents an ideal way to explore this fascinating World Heritage Site.
