The 08:00 bus might be the 09:15 bus.
If that sentence just tightened something in your chest, go to Portugal. You will have a much better holiday and nobody will think less of you.
Still here? Good. Then this is your region, and this is the guide that treats you like an adult about it.
In the Balkans the currency that matters is not the euro, the mark, or the lek. It is time. Between Split and Dubrovnik the road passes through Bosnia's twenty kilometres of coastline, which means two passport stamps in forty minutes of driving. Debeli Brijeg, the crossing into Montenegro, is ten minutes in May and an hour in August. No amount of road quality fixes this, and no guide that quotes you driving distances is telling you the truth about your day. So this one quotes journey times with the border built in, names the bus companies, tells you which terminal they actually leave from, and gives you a matrix of the legs you are likely to travel so you can build a route that survives contact with a timetable.
The other thing it does is send you slightly sideways.
Bohinj rather than Bled. Cavtat, twenty minutes down the coast, rather than a bed inside Dubrovnik's walls. Perast, where no cruise ship can dock, rather than Kotor's waterfront in the middle of the day. Zadar rather than Split. Ulcinj rather than Budva. None of these are compromises. Every one of them is the better version of the thing you came to see, minus the queue, and usually for half the price.
Albania gets the honest treatment it rarely receives: the cheapest country in the book by a wide margin, where you eat properly for eight euros and sleep well for thirty, and also the one where the tarmac occasionally just stops. Bosnia gets more than the bridge at Mostar — Una's waterfalls, Sutjeska's primeval forest, the wine country an hour south. There is a chapter on the landmine question that neither dramatises it nor waves it away, and it comes down to one rule you can memorise in four words and follow for three weeks without ever thinking about it again.
You get daily budgets by country at three spending levels, month-by-month notes on what is actually open, forty phrases that will get you further than you expect, and the etiquette of talking about the nineties with people who lived through them.
And four routes, seven days to twenty-one, written to be followed or dismantled.
Go in June. Take a paperback. The bus will come.
