Travel smart
Tap water is safe to drink. Not expected. Service is usually included.
Luxembourg City's old quarters are built across deep river gorges spanned by dramatic bridges, giving the compact capital a genuinely three-dimensional layout unlike most European cities. Despite its tiny size, smaller than Rhode Island, the country packs in dense medieval castle ruins across its 'Little Switzerland' region and became, in 2020, the first country in the world to make all public transportation free nationwide.
When to go
SpringApril–May
Mild and blooming, a good window for the countryside's castle trails before summer crowds and heat.
SummerJune–August
Warm and the busiest season, with outdoor café culture and hiking trails at their most popular.
AutumnSeptember–October
Comfortable temperatures and vivid forest color, particularly in the 'Little Switzerland' region.
WinterNovember–March
Cold and often grey, but Luxembourg City's Christmas markets are a genuine highlight through December.
