It is divided into three chapters: Zermatt; Grächen, Randa and the Mattertal; and Saas-Fee and the Saastal. The routes are graded from 1 to 4 and range from 4 to 18km. They are best walked between mid June and mid September. Most are on well-made mountain paths, although a few are on steep and rocky trails with exposure. There are routes to suit all tastes, from easy strolls up to mountain restaurants, lakes and viewpoints through to serious mountain challenges. Zermatt and Saas-Fee offer superb walking in the shadow of the Matterhorn. Both villages have a full range of facilities and there is a plenty of accommodation throughout the Mattertal and Saastal. There is ample opportunity to make use of Switzerland's an excellent public transport infrastructure to give access to walks. Distance, walking time, ascent, descent and difficulty are shown for each route, and the route description is supported by clear mapping. An appendix of contacts list sources of information, helpful websites and apps, and there is a useful English-German glossary.
