Mountaineering refuges (planinarski dom)

Definitely the best solution if you're heading for the mountains. Accommodation prices range from 3 to 5 euros per night, and there are dozens of such places scattered all around Serbian mountains. Sometimes they are cozy and well equipped, sometimes shabby and old, and usually have small kitchens where you can prepare your food. Some of them are open all year round (Old mountain), for some of them you have to call in advance for the keeper to come and unlock it for you (Besna Kobila mountain), and sometimes they only work with groups so you have to argue a bit before they let you in (Beljanica mountain). The keeper is usually a person living in one of the nearby villages, and the best way to reach him is to contact the local mountaineering club. Don't expect English to be spoken, so you definitely need a local's help to arrange a stay. If you are sure the refuge is open all year round, you can just show up there. Make sure you know where it is, and don't forget to bring your map otherwise you can get lost in the mountains.
