Romania
Romania is one of the least expensive travel destinations in Europe, particularly if you want to hike in the Carpathian Mountains or are mainly interested in seeing the countryside. Even a trip to Brasov, where Dracula's Bran Castle is located, may be extremely reasonably priced if you sign up for a sightseeing day tour or don't mind taking a slow train out of Bucharest.
Romanian trains are safe and fairly affordable, though they are not always in the best condition. The Old Town from the fifteenth century, Revolution Square, and Romania's own Arch of Triumph are some of Bucharest's most stunning landmarks, and they are all either free to enter or very reasonably priced. You might take one of the many free walking tours that leave from the town center, or you can rent a bike in the warmer months to explore smaller cities. Most of the time, grocery shopping here is not worthwhile because eating out is affordable and filling in Romania. Local specialties like sarmale (cabbage rolls), cozonac (sweet bread), or mamaliga (polenta, usually served with sour cream and strong cheese) are cheap, frequently available at street food vendors, and a great way to sample some Romanian food.
