Though we wouldn’t really call it a “secret” anymore, some of the best outdoor adventures in Europe can be found in the little Balkan country on the Adriatic Sea. Diving, whitewater rafting, and hiking in Montenegro are as good as they are anywhere on the continent, and few places offer all three in such a small area. Adrenaline junkies can get their fix here too, whether it’s kitesurfing near the town of Ulcinj or skiing in Durmitor National Park.

If you’re not so much for exhausting yourself, perhaps a train trip through Montenegro is more your speed. That’s cool, rides here are plentifully scenic, especially with the changing colors in the fall. You can even take a cruise to Montenegro, and we’ll tell you why it’s the world’s top cruise destination.
