Three months solo travel around Europe itinerary ideas and advice please (25F)

You are welcome, since you are going to Poland and Hungary , they are not very far also from Budapest you can go to Vienna then Prague then Wroclaw they are all close and just around 4 hours or 5 by train between each of those cities.as for France italy Netherlands and switzerland it depends also on the cities . Paris to Amsterdam for example is also accessible by train just 3 hrs i think and also if you plan on visiting the south east of France , Italy and switzerland will be pretty close too. What i would advice you to do is to try and estimate how many days you want to stay in each country, then start planning your trip , some cities would take just 2 to 3 days to visit , some would take longer so consider all that .
