Keen to tick a new country off your European bucket list? Pay a visit to the world’s only remaining Grand Duchy, a nine-hour trip from the UK's southeast by trains and buses or a seven-hour drive. The hilly, verdant nation is full of fairy-tale castles, such as Berg, whose white turrets can be seen for miles around. Hungry? There are eight Michelin-starred restaurants in the micronation. Oh, and when you get to Luxembourg, public transport is free, so you can travel about as much as you wish.
