To get there rail is simply the best option: take the Eurostar to Paris and then, a few platforms away at Gare du Nord, there’s regional rail to Amiens, a journey that takes about an hour and a half. I travelled with Trainline, which has an app for all the tickets, which is particularly handy when you’re making a rapid transfer from one train to the other. You could make the journey in a day: an early train from St Pancras gets you to Amiens by lunchtime, and so you’re good for the four or five hours before the market starts to close, around 4.30-5pm, with time for a bowl of cider and a ficelle, the local stuffed pancake, before returning to Paris for a late train back.
