What mistakes do travellers make in Switzerland?
The classic Switzerland mistakes are over-moving, under-budgeting, ignoring weather, buying rail passes without doing the maths and treating every mountain viewpoint as essential. The country is efficient; that does not mean the trip should be overloaded.
Answer
Switzerland makes travel feel smooth, which is why the mistakes can be subtle. Trains run well, but changing bases every night still drains the trip. Mountain viewpoints are easy to reach, but not every famous one is worth paying for in bad weather. Rail passes can be useful, but only after the route is known. Cities are pleasant, but using expensive city hotels as distant mountain bases can make the days clumsy. The better Switzerland trip is edited: fewer bases, clearer priorities, weather-flexible alpine time and a budget that includes the lifts, food and accommodation you are actually likely to choose. Efficiency helps. It does not replace judgement.
