car travel from fuzzen to Murren to black forest

Leave it in Füssen. You can go by train from Füssen to Mürren, and from there to the Black Forest. If you know the rail systems, you won't need a car.

Thanks for the reply. Since we need to drive back to Brussel, and on the way we like to stop by different towns. Is there an option to drive?

You can also get to Brussels by train. Have a look at the Bahn.de website for information on rail schedules to each of the places you'll be travelling to. Unless you have lots of time, using the excellent rail network is the most efficient travel method. The high speed trains run at up to 300 km/h, so much faster than a car.

Note that if you're renting the car in Brussels, you'll need to obtain the Swiss tax vignette or risk hefty fines.

Thanks Ricks team for the suggestion. Here is my itinerary:

Day 1 departure stay

Day 12 murren murren

My family contains 2 kids 7 and 9 and a baby of 1 year old. Any suggestion on where should I pick a car and where can I use the rail. or if I can change my route a little big. The reason I picked car was thinking it's flexible at some route. Appreciate your help. Thanks

Day 11 will be a toughie.

Is there something in particular you want to see in Bern? It is out of the way and will add hours to your already busy day.

With the 2 children it is handy to have extra storage with the car, but if you plan to leave the car with luggage in it while you do something you are making the car a target.

If it is just you and the two children you will likely find the train much easier and cheaper, and you will be able to look out the window and amuse the kiddoes instead of driving and taking over your shoulder to them.

Are they both of sufficient height and weight that they don't legally require booster seats? They should both be in the back seat for safety, just like at home.

The baby will need to be in an approved baby carrier in the car.

You won't need any of that, although you may want a stroller/pram/push chair for baby, on the train.

Day 3 - do you mean the middle Rhine where the castles are and you can ride a boat through the best bit? If so, that is easily done by train, but if you use a car you have to back track to get the car. You won't be leaving any luggage in car, I hope.

Day 14 - if you stay in most of the towns and villages (where do you have planned, I like Gengenbach) in the Black Forest except Freiburg im Breisgau you will probably get a KONUS card when you check in, which gives you free transportation within the Black Forest area including on the scenic train which goes through it.

Do any of your children like model railways?

Nigel,

Thanks for all the suggestions. My family will be me, my husband, and 3 kids.
Good point on car seats. My friend just told me the train is slow and need to be on schedule. That's the reason I picked the car drive since I can drive any time and do not have to be on time. I need to explore the train option as well.
I thought Germany is safe and I can leave the car at parking log behind for some days.

For 2 days in Rhine, I planed to stop at Beilstein and visiting Eltz Castle first, and then visit St. Goar second day and wondering around the river.

Day 11, I meant Berner Oberland. Is this where I can pick up the lift to go to Murren. Is there a place I can leave the car in Berner Oberland or I better off drop the car in Fussen and take the train to finish the rest of the trip?
Day 14 Black Forest , not sure where to stay yet, but plan to visit open air museum and the clock museum.
