The majestic Austrian Alps stretch across the country, an awe-striking area of Ice Age valleys, verdant heaths and alluvial cones within Europe's largest national park, 700-square-mile Hohe Tauern. Taking in the dramatic cities of Salzburg and Innsbruck and the beautiful province of Tirol, home to spectacular skiing and hiking, as well as Gross Glockner, Austria's highest peak, and some of the world's best winter and summer sports playgrounds, the Austrian Alps are an outdoor lover's paradise.

Sprawling along the edge of the Thermaic Gulf, Thessaloniki is a seaside showcase of Greek history from ancient Roman and Byzantine ruins to the modern high-rises lining its beaches. Plus, after sundown, Greece’s cultural capital hums with some of the best nightlife options in the Aegean.

The Ionian Islands are splendid, cinematic paradise. The waters are bluest blue, the sands are achingly silky and smooth. Everything looks heavily Photoshopped. But that's just Mother Nature, in all her unspoiled glory. Zakynthos is the largest of the Ionian Islands, and it's as fruitful as it is beautiful, boasting a bounty of crops like olives and grapes. Music is a huge part of the local culture—you can catch a concert or festival almost any night of the week, and you'll be captivated by the sights and sounds of Zakynthos performers.

Visit Provincetown and have a blast enjoying some of Cape Cod’s best beaches (Race Point Beach and Herring Cove Beach are favorites of TripAdvisor travelers). Plenty of cool boutiques, restaurants and art galleries give this town a fun and funky vibe. It’s an exceptionally LGBT-friendly destination as well. One tip: if it’s high season, take the ferry or a quick flight from Boston (unless you enjoy spending hours sitting in traffic).
