If two wheels are your thing, there are numerous stunning mountain bike routes, such as the Grand Raid Cristalp from Verbier to Grimentz, scene of the race billed as the toughest in the world. But most routes are designed for families, using a combination of quiet lanes and off-road, well-surfaced tracks. The creation of the SwissMobility system (switzerlandmobility.info) has made it much easier to explore Switzerland by providing a complete holiday booking service through Swiss Trails. Bikes are provided, hotels booked, maps and guides supplied, and luggage transported.
For example, the 320km Rhône route between Andermatt and Geneva can be done in seven easy stages. The only really steep part, the climb to the Furkapass, can be avoided by putting your bike on the train - although you would miss the Rhône glacier and some spectacular scenery.
Swiss Trails also arranges canoeing and walking holidays. Half the Alpine Passes trail between St Gingolph and Chur is in the Valais. That section alone provides two to three weeks' walking through some of the most remote parts of the canton, staying in mountain huts some nights and carrying few essentials between hotels.
