請問如何從瑞士往巴黎？

You can take the train from Geneva to Paris, a journey that only takes about 4 to 4.5 hrs. The train gets you to Gare de Lyon, which has a metro station that will connect to the rest of the city, very convenient.

Unless you buy an open-jaw ticket, which allows you to fly into London, and out from Zurich, otherwise you will have to include one budget airline flight. If you have an open jaw ticket, then your route can be:

HK - London - Train to Paris - Train to Geneva - Train to Zurich - HK (or the opposite direction)

Route including a budget airline flight is similar:

HK - London - Train to Paris - Train to Geneva - Train to Zurich - Budget flight to London - HK

There's not much you can do about the route - but do take the train from Geneva to Paris - the one from Zurich to Paris is around 7 to 8 hrs.

Have fun!

OR

HK - Zurich - Train to Geneva - Train to Paris - Train to London - Budget flight to Zurich - HK

係瑞士(Bern)坐火車去巴黎只係四個半小時. 蘇黎世或日內瓦我想應該差不多吧!
未夠25歲可買小童火車飛.

好少人咁行，通常由倫敦過巴黎到法蘭克褔落蘇黎世，全程可以搭火車，最好改機票由蘇黎世走，唔係要坐好耐車番倫敦，當然搭飛機例外。
