Most trails in Switzerland are documented and clearly sign posted, and along these routes you find written way-points, as well as coloured stripes on trees or rocks showing you the next degree of difficulty or hazard. Very little map reading capability is required, but I recommend that you carry a local guidebook, a GPS, and a cell phone. (If you fall or injure yourself, you can call for help and even helicopter evacuation). Walks in the Canton Vaud and Canton Valais I find to be the prettiest and easiest during the period between May to mid August. This is the area within striking distance of Lac Leman (Geneva, Lausanne, Montreux, Martigny, and Sion), taking in the Jura Hills (up to 1470mts) and the Pre Alps (up to 2400mts). Base height of Lac Leman on the Plateau (Lake Geneva) is 380 mts. Trekking farther a-field in the high Alps (Zermatt, Interlaken, Monte Rosa areas) can give you majestic views and take you from a base altitude of approx 1800mts up to 4200 mts. Mont Blanc is in France and clouds permitting, can be seen from most areas. Before attempting high altitude walks it is strongly recommended that you take local advice (and maybe a guide), as people are killed every year in the mountains owing to rock falls, sudden weather changes and just foolhardiness in obvious dangerous areas. If you live at sea level and are coming directly to an altitude above 3000mts you may find that you suffer from shortness of breath and giddiness. I would therefore recommend that you spend some days acclimatising your bodies walking in the high Pre Alps region (around 2000mts). For walks that you will love with spectacular views, good food, wine and accommodation, I suggest that you use the Montreux area as a base and buy a local walking guide once you are here. Most starting points are within easy reach of Montreux and can be accessed by bus, train, boat, funicular, or cable car. You can either stay in small mountain inns (auberge), or carry a tent and camp in their back gardens. Base language in this area is French. However, German, Italian, and English are taught in all schools, and owing to the cosmopolitan nature of the region and the high tourist saturation all year, people even understand the American and Australian dialects.
