The TGV Lyria serves Neuchâtel from Paris Gare de Lyon with three pseudo-direct ticket per day. First class passengers are entitled to a restoration in their place as the train crosses the border.
It is possible and easy to change to Frasne to catch one of the many Lyria TGV to Paris that comes from, or goes to, Lausanne.
There are no reservations for Swiss trains. The network is very dense and the trains very frequent. Generally there is one train every hour from any major city to any other. There is no difference as great as in France between the second and the first class, but the price is doubled. You have to buy the ticket before you get on the train, and there is no composting. You have to pay the full price, the half-price requires the purchase of a specific half-price card (which is quickly profitable if you often come to Switzerland).
For those arriving by plane from Geneva airport, or Zürich, there is a direct train connection between these two airports and Neuchâtel.
Neuchâtel is close to the following airports:
Geneva airport [1h13 by direct train]: GVA is the hub of the company easyjet, but also of Brussels Airline. Easyjet serves Nantes, Bordeaux, Lille, Nice, Toulouse and Paris Orly.
Zürich Airport [1h52 by direct train]: ZRH is the largest airport in Switzerland with connections to many French cities, including Low Cost (see in particular German Wings to come from Nice, or Brussels Airline to come from Toulouse).
The EuroAirport Basel, Mulhouse, Freiburg [1h50 via Basel] is also an EasyJet hub at a distance comparable to that of Geneva. It is however necessary to take a bus to Basel station, which is less convenient.
The airport of Berne [1h15 via Berne] is smaller but it can be an option for those coming from Paris or London. There is no direct train to Neuchâtel.
It is possible to come by car, taking into account the following two points:
If you wish to use the Swiss motorways, you have to pay a sticker worth 40, - CHF, which is sold at service stations and at the border crossing.
It is possible to reach Neuchâtel without using the motorways, especially if you pass through the town of Pontarlier or by Morteau
In Switzerland, the color of the panels is the reverse of France: green for highways, blue for normal roads.
It is not easy to park a car in the city center and the car parks are expensive. It is recommended that you contact your hotel or the tourist office to let you know where to park for free or at a reasonable cost.
