I was an American wandering the Muslim Quarter with nothing but Croatian currency in my wallet when I arrived. I asked someone at the bus station if the Kuna (Croatian) was accepted and she shook her head indicating that it was not a good idea. After getting robbed in Split, Croatia, my choices were limited and my access to cash was basically cut off, so needless to say, I was very budget conscious while in Mostar. I had read that one might experience some resentment toward Westerners here and the lady's reaction to the Kuna at the bus station confirmed this.
Fortunately, I was able to find a tourist information place (privately run) and a lady who spoke good English. She was able to exchange some Kuna for the local currency, the Convertible Marka (at a terrible rate for me, but oh well!).
Throughout Mostar you will see buildings that were shelled, tank-blasted and dotted with bullet holes. In fact, I'd say that at least 70% of the buildings in the Old Town are still showing obvious scars of the war.
As of May 2004, we were not able to exchange money in Mostar, as well as at the Croatian border, on Sunday. We did not find any ATM mashines in the city, and the exchange offices are closed on Sunday. Contrary to some reports, shops would not accept Euros or Croatian kunas (I assume the bus station, too). I do not know how this problem is commonly solved. Apparently, on a weekday money can be exchanged at the post-office.
Don't park your car when you see the warning like this one. There are lot of damaged buildings in Mostar and people use to park in front of them on pedestrian pavement. There are lot of parking spots where you can park your car without worry that it will be destroyed.
After two days of non-stop rain, Radoblja River started to flooding. Not to imperil the city, but terraces around it were flooded. I heard the story that during the war, Radoblja expose to damaged Crooked Bridge.
Croatian Mostar is the only potentially unsafe area of Mostar. See the Croatian flags? See people paying with Croatian money? Extreme nationalism doesn't make this area completely safe, unfortunately. In this area, in particular, you should make sure to keep a low profile, and also not to walk onto deserted building sites or fields, as you may step onto a landmine.
mostar is safe enough to visit, walking on the streets you can imagine how the war had been, people is friendly and helpful, there are a lot of UN forces all around the city but the thing is relaxed enough.
Sadly you will see bombed out buildings all over Mostar. You must not go inside any as they are dangerous. They are a poignant reminder of the horrors that took place here.
Iv"ve been to Mostar twice , both in September, I can say be prepared for heat. It was over 30 c this time.
There has been many shelling from Croatian side and there are still many sites are warned against possible unexploded or undiscovered explosives!
