The main reason I went to Liege was the weekly Sunday market called 'La Batte'. It is one of the oldest street markets in Europe and spreads along the bank of the Meuse River for about a mile. Most of the stalls have colourful coverings and, even if it's raining, it's still fun to wander through the stalls filled with clothes, food, jewellery, etc. People come from all over, including Holland and Germany, and it's a great spot for people watching even if you don't shop.${QuickSuggestions} Grab a quick & cheap bite to eat from one of the many stalls selling food.

Liege is located in the Wallonia part of Belgium and the people speak French. ${BestWay} The sights I list are a bit spread out but traffic was pretty congested at times, so you're still better to park the car & walk. There are also city buses if your feet get tired.
