Begin your journey to the peaks of Switzerland by taking the Eurostar from London St Pancras to Paris Gare du Nord.
On arrival in Paris, transfer to Paris Gare de Lyon for your connection to Switzerland. Start by taking the scenic high-speed line to Basel, before connecting to the mountain resort of Interlaken.
Check into your hotel, your base for the next two nights and spend the evening at leisure. You could spend some time exploring Interlaken's bar and restaurant scene, or simply put your feet up at your hotel after a long journey.
