There are plenty of hostels in both Sarajevo and Mostar (dorm beds costing around €12), as well as private rooms in these cities, though they’re pretty rare elsewhere. Otherwise, hotel accommodation is still pretty cheap in Bosnia-Herzegovina – you should always be able to find a room in the €25–35 range. Guesthouses (pansiona) are available in some towns, though are nowhere near as numerous as in neighbouring countries. Free wi-fi access is now almost standard in all accommodation. There are a few campsites dotted around, most with reasonable facilities (en.camping.info/bosnia-herzegovina). The possible presence of unexploded mines from the war means that wild camping is not a good idea.
