First up, check the validity of your passport and whether you need a visa. Then decide the best time for you to visit Switzerland.
Which places you visit may be dependent on how you plan to travel around and whether or not you have any specific interests. It can be tempting to try to fit too much into your trip.
After the major expenses of flights and accommodation, I usually allow around CHF 800 per week for two adults to cover meals, groceries, tours and sightseeing that I haven’t pre-purchased.
The main options are train, car and an organised coach tour. If your time is limited, a tour is worth considering. Travelling by train is a most relaxing and scenic form of transport.
The variety of accommodation is huge. From hotels to B&B's as well as more than 50 youth hostels, there's accommodation to suit any budget.
It’s worth considering purchasing a regional transport and sightseeing pass. They usually include all public transport in the local area and discounted travel on cable cars and mountain railways.
