Visp area, map No. 274T, at 1:50, 000 in a special hiking edition of the country’s topographic survey, published by Swisstopo in cooperation with the Swiss Hiking Federation. Coverage extends southwards from the Rhone Valley & Brig to include the lower part of the Mattertal beyond Grächen & St. Niklaus, the lower part of the Saastal & the Simplon Pass. Cartography, identical to the standard version of the survey, is highly regarded for its superb use of graphic relief & hill shading to provide an almost 3-D picture of Switzerland`s mountainous terrain. Contours are at 20m intervals. An overprint highlights routes maintained by the SHF, distinguishing between hiking routes, mountain routes requiring proper footwear, & alpine routes where equipment is needed. Paths which are part of the national or regional network of long-distance hiking routes are specially marked & in the more recent editions are annotated with their official numbers. The maps show mountain huts, refuges & in remote areas also inns, plus roads with bus service & the positions of bus stops. All the maps have a 1-km grid of the Swiss national coordinates.
