They are not the first or last to promote convenience and at times pleasures of train travel in Europe.
Most prominent I think The Man in Seat Sixty-One.
Snowcarbon does not stop at that.
The team at Snowcarbon helps you reach your winter sports destination in the most earth-friendly way.
They also put the combined ski and travel knowledge of their 12 writers to help you make the most of each mountain resort from dusk to dawn.
A few reason they offer to choose train over plane or car are that it is comfortable and relaxing, scenic, family friendly and without luggage fees (unless you travel like a king).
In France, besides the Eurostar service, another possibility to Bourg-St Maurice for example is the Corail Lunea for those who want to travel overnight (with sleeper car option)...
Snowcarbon selected 30 resorts in 4 European countries (Austria, France, Italy, Switzerland) plus Andorra and offers guides designed with travel from the UK in mind.
I am sure they can be of use for people from other countries who will just need to tweak the itineraries.
Snowcarbon was founded by Daniel Elkan and Mark Hodson.
