We will be driving from Czech Republic to Switzerland for about 10 days.
Please share your tips on safe and enjoyable driving.
Also, is it worth driving to Lichtenstein?
Any tips will be appreciated.

Thank you

Hello Marmot! Lots of information on driving in the Swiss mountains, including rules you should pay attention to, can be found here. If you follow these tips, driving is very enjoyable, especially if you select scenic pass routes (and there are lots of them).

I suggest that you take a look at the Liechtenstein tourism website to see if that appeals to you. As for landscape and scenery, it's not that different from the eastern part of Switzerland.
