You’ve been called the energizer bunny. You have two speeds: On and off (and the latter is a rarity). Buenos Aires has the non-stop action you crave. With its splendid architecture, colorful street art, cultural attractions, delicious dining scene, and famously vibrant nightlife—from swanky lounges to milongas (tango halls)—there’s never a dull moment in this lively city. That’s why it’s on the list of increasingly popular travel destinations. Bonus: It’s also one of the best budget-friendly destinations.
Inquisitive: Edinburgh, Scotland
A seemingly endless series of narrow alleyways, covert courtyards, secret gardens, and hidden gems waiting to be discovered, Edinburgh is like a treasure map come to life. Inquisitive types can channel their inner Sherlock Holmes with a visit to Gilmerton Cove, a network of hand-carved underground passageways shrouded in myth. While there are numerous theories regarding the origin and function of these curious caves, the truth remains unknown. Adding to the mystery is Edinburgh Castle, considered one of the most haunted places on the planet.
