If you actually want to take a hike in Switzerland (and of course you do!), there are all levels from hikes for flatlanders to experts to alpinists. (See Swiss Alpine Wanderlust Packing List for Serious Hikers.)

So don’t let those enormous Alps intimidate you, because you can do a lot at lower altitudes. You might start by hiking around the Swiss vineyards, a common practice in Switzerland, or even in villages; you can hike down to the lake and the one of the relaxing and scenic cruises on Lake Geneva. Whatever the activity you will need a picnic lunch and the best place to find the ingredients is the Swiss supermarket.
