Mostar

Mostar is a tourist trap worth visiting but you can be in and out in a day.  The Old Bridge is the main attraction, no photo of it comes out bad, and during the day members of the Mostar Diving Club can be seen jumping off it. It's worth going to the main mosque - no longer a functioning mosque, and now a tourist attraction - where for 8KM you can go up in the minarette for an incredible view of the bridge and the city. But skip it if you're afraid of heights - the only way up and down is a spiral staircase wide enough for one, and there isn't much of a railing at the top. The bridge museum is worth a trip if you have the time and are interested in the history of the bridge and more recent reconstruction after it was destroyed during the war in the 90s. 

The old town now really caters everything to tourists, and there are many so hostels and plentiful and english menus are the norm. For E20 Pansion Lombrelle offers a large private with a kitchen and balcony 5 minutes from the old bridge. In the center is a Bosnian restraunt where hosteses wear traditional costumes - this is supposed to have good food, but take the left just before the restraunt and go to Hindi Han which offers very good food at a very reasonably price and if it is any indication is usually bustling with far more locals. 

Around the outskirts of the city the remnanst of the war are very visible - bombed out buildings are left to decay, "Dangerous Ruin" signs warning people from entering.
