I visited this WHS in April 2014. I travelled by car via Medjugorje as the highway from Split was closed just after the lengthy border crossing. It took much longer to arrive this way but looking on the bright side, it gave me the opportunity to visit Medjugorje and drive past several vineyard fields without encountering any problem whatsoever. Euro currency is accepted almost anywhere but you can easily find foreign exchange outlets in Mostar. Apart from the symbolic importance of the Stari Most (old bridge), the Muslim side is very interesting with a small bazaar, an Ottaman house and a small mosque open to the public. Dress code is not as strict as in other mosques around the world and you don't need to take off your shoes for example. The highlight of my trip was climbing the Koskin-Mehmed Pasha's Minaret as I never climbed a minaret before. Moreover, it offers a great panoramic view over the old bridge (photo). On the whole Bosnia is the least developed of the Balkan countries I visited and the one which has least recovered from the war - there are still bullet holes on the building facades and bombed buildings all over the country. Nonetheless it is a very interesting country and well off the beaten track, especially in the Serbian Republic side of Bosnia & Herzegovina. Keep your eyes open when driving through the countryside as you'll surely meet cattle with long horns, sheep or goats crossing the roads! So be extra careful and enjoy!
