With its landscape of mountains, glaciers, deep gorges and fast-flowing rivers, Switzerland is ideal territory for adventure sports . Dozens of companies based in all the main resorts operate thrill-making schemes galore, mostly in summer only (typical prices are in brackets): canyoning (half-day Sfr100), river-rafting (the same), bungee-jumping (from 100m Sfr80; 150m Sfr150; 180m Sfr220), zorbing (where you're strapped inside a giant plastic sphere and rolled down a mountainside; Sfr50), house-running (where you hook a rope round yourself and run full-tilt down the side of a tall building; Sfr70), flying fox (where you glide down a vertical cliff on a rope; Sfr75), and more. Hang-gliding (Sfr130), paragliding (Sfr170) and skydiving from 4000m (Sfr400) can all be done alone or in tandem with an instructor. Two main centres for adventure sports are Interlaken and Luzern; you generally book at the company's office in advance, then get bussed out to their preferred site in the mountains and back into town afterwards. Local tourist offices always have full information.
