What practical mistakes do first-time visitors make in Serbia?
The mistakes are usually practical rather than dramatic: assuming cards work everywhere, leaving transport too vague, treating taxis casually, and expecting English to solve every small-town problem.
Answer
Serbia is not a hard country to visit, but it does punish vague planning in small ways. Arrive without a transfer plan and the first taxi feels bigger than it should. Assume every place takes cards and you may spend too much time hunting for cash at the wrong moment. Rely on English everywhere and the easy city confidence can fade in bus stations, markets or smaller towns. Overload the route and you discover that a short-looking country still has slow days. None of this should scare you off. It just means doing the boring work early so the trip can spend its energy on food, streets and people rather than avoidable admin.
