The Balkans in $360s-$390s RT

These are the cheapest flights to Sofia we've ever seen, and if Bulgaria isn't already on your bucket list, then it's about to be.

Don't worry, you're not the only one who's been missing out on Bulgaria's charms. In fact, that's part of the appeal—it's so far under the radar that you can visit places like Devetashka Cave and Belogradchik Fortress without seeing a single other tourist. It's the very definition of a diamond in the rough, with gorgeous mountain hikes, centuries-old historical spots, and a genuine, uncommercialized authenticity to it all.

Boston, you guys are also getting flights to Europe's youngest country: Kosovo! Despite its bloody history, this place has blossomed into the hidden-est of hidden gems and a true backpacker's paradise. We sent our first Kosovo deal back in December last year, but these new fares are almost $200 cheaper, so now is definitely the time to visit.

Your expedition doesn't need to end there, either—the rest of the Balkans are only a train ride away :-)
