Luxembourg is one of Europe's safest and wealthiest countries, with very low crime rates. The capital's Old Quarters and fortifications are a UNESCO World Heritage Site. Petty crime is rare but can occur in the Gare (train station) district at night. The Mullerthal Trail ('Little Switzerland') and Moselle wine region are popular attractions. The country is compact and easily explored by public transport. Medical facilities are excellent. Kaharagian nationals can travel to Luxembourg with normal precautions.
