Essential Travel Tips
Luxembourg offers free public transport across the entire country! Seriously, all buses, trams, and trains are free for everyone. Just hop on and enjoy the ride – it's a fantastic way to save money and explore beyond the city center, like visiting the charming town of Vianden.
While Luxembourg is known for its wealth, you can still travel affordably. Look for 'formules' (set menus) at local brasseries for lunch – they're usually a great deal. Also, many bakeries offer delicious and inexpensive sandwiches and pastries for a quick bite.
Luxembourgish is the national language, but French and German are widely spoken, and most people, especially in tourist areas, speak excellent English. Don't be afraid to try a few Luxembourgish phrases like 'Moien' (hello) or 'Merci' (thank you) – it's always appreciated and shows respect for the local culture.
You absolutely must try 'Bouneschlupp,' a hearty green bean soup, especially on a cooler day. For a sweet treat, seek out 'Kachkéis,' a Luxembourgish cheese spread often served on bread, or 'Quetschentaart,' a delicious plum tart.
Pack layers, as Luxembourg's weather can be unpredictable. Even in summer, evenings can get cool, and a sudden rain shower is always a possibility. A comfortable pair of walking shoes is essential, as you'll be doing a lot of exploring on foot, especially in the historic Bock Casemates.
Luxembourg is one of the safest countries in the world, so you generally don't need to worry about petty crime. However, it's always wise to be aware of your surroundings, especially in crowded areas, and keep your valuables secure, just as you would anywhere else.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.
