Lonely Planet is on a roll. The travel company released their Best in Travel lists this week, including the countries you need to be visiting (hint: Singapore) and the budget destinations to hit up next year.
Also on the list, of course, are the 10 cities you should be visiting in 2015. You're likely familiar with quite a few of them, like Washington, D.C., Toronto and Milan, but the same might not be true for others.
Three cases in point: El Chalten, Argentina, aka the trekking capital of Argentina, Valletta, the charming capital of Malta and up-and-coming Plovdiv, Bulgaria.
Here are the 10 cities you should schlep to next year.
