Namur is located 60 km south-east of Belgium's capital city, Brussels. It is easily accessible by road (the E411 highway from Brussels), train or boat (the Meuse comes from France and the Samber flow through Namur where they actually meet).
Namur is a substantial city and might be too large to discover on foot. The layout of the city is complex and navigation is not easy. Cycling does not appear to be very popular with the locals, perhaps due to the number of cobbled streets. On the other hand, many one-way streets are "except bicycles", so cyclists enjoy special privileges.
Hire a bicycle and cycle up and through the Citadel. This is better than doing it on foot as the access road is mostly wide and uninteresting. There is also a network of mountain bike itineraries beginning and ending in Namur, but the signage, which is very good at the beginning, with large coloured arrows painted on the road, suddenly vanishes without explanation.
A tour company in nearby Dinant (Les Kayaks Bleus, www.lessekayaks.be) organises river kayaking trips. It would probably be possible to paddle downstream all the way to Holland and the North Sea.
There are public swimming pools in Salzinnes and Jambes.
Namur is often said to be an "open sky" shopping mall. Major shopping streets stretch from the Namur train station to Rue de Fer and Rue de l'Ange where you will find normal fashion outlets like H&M, Newlook,Zara, Kim Pie,Cool Cats, O' Appels, Charles Vogele Switzerland, Esprit, JBC, C& A, Women's secret, ICL Paris IV, Di, Camaieu among others.
The inner city supermarkets are one Match and one (smaller) Spar. Other supermarkets are Carrefour and COlruyt in Jambes and another Colruyt and Delhaize in Salzinnes among others.
Namur might also be your gateway to the Ardennes and Luxembourg. There is an international train going to Basel, Switzerland and from there to Zurich and Chur.
