Travelling from London to Italy's Amalfi Coast. Better to fly or take the train?

I would personally recommend taking the train - it means you can see the landscape change as you travel south, rather than bypassing it in the plane (also taking the train is lower carbon so better for the environment).

You can take a train from London to Paris, Paris to Milan, and then a night train from Milan to Naples, arriving at Naples in the morning:

(Disclaimer - I run loco2.com)

Unfortunately this option is likely to be much more expensive than flying. This makes me very sad, but is something that unfortunately we don't have much control over at Loco2.

You might be able to find cheaper options than Loco2 for the Paris-Milan leg of the journey at Thello.com (this site is only in French), and for the Milan-Naples leg of the journey at TrenItalia.com (this site is in English but can be quite confusing unfortunately).

You could also consider splitting the journey and stopping off in Paris and Milan. This is unlikely to affect the price much, and would make for a great adventure, but obviously you'd need more time.

I think it's worth adding detail for the Naples - Amalfi coast part of the journey. I'm assuming you're going to Sorrento, as that is the route I am familiar with.

If you do get the train to Naples, you'll want to change at Napoli Centrale station for the Circumvesuviana train to Sorrento, which is the end of the line. Pompeii (Pompei Scavi station for the Roman rather than modern town) is on the way, but you'll want most of a day for that.

If you fly to Naples airport, you can either:

• get a direct bus to Sorrento. While very scenic, the coastal road is very narrow and winding in places, and can get very busy (e.g on a Friday night) which can make for a frustrating and uncomfortable journey.

• get the 'Alibus' to Napoli Centrale train station and get the Circumvesuviana train from there - no train station at the airport. Probably not worth the bother, unless you want to spend some time in Naples, e.g, to visit the Naples National Archaeological Museum (Museo Archeologico Nazionale di Napoli) which has a lot of sculpture from Pompeii and Herculaneum (there are very few artifacts at Pompeii).

• stay on the Alibus to the port and get a fast catamaran to Sorrento from there. Very quick, fantastic views of Vesuvius and the coast (I spent the whole trip standing on deck), relatively expensive. Arriving at Sorrento's port is quite spectacular, although it's a very steep walk up to the town, you'd pretty much need to take a bus or taxi if you have a suitcase.

Regarding the Naples to Amalfi leg, I took ferries, and would suggest them as an option too. Note that this is the most complicated part of the trip in my opinion, so merits expansion of other options.

• The ferries are more scenic, and get you to the better parts of town, and are not as constrained by the traffic jams that can occur from Naples to Amalfi.
• Ferry schedules can be found here.
• Getting to Sorrento is simple, just take a ferry from Naples.
• You can take a ferry from Naples to Sorrento, and then Sorrento to other Amalfi towns.
• You can alternatively take the fast train to Salerno, a ferry from there ( I did not try this, but if I had to do it again, would probably try this ).
