Narva is the third largest city in Estonia. However it is a really small town with all the sights within walking distance.
The walks are made even more memorable by different thematic tours like city quest or audioguide that can be rented from Narva Tourist Information Centre which is located on Town Hall Square (Raekoja plats 1) and open 10-18 daily. You can also take free city maps, information about the whole country and guides` contacts from here.
