Stretching along the southern side of Italy's Sorrentine Peninsula, the Amalfi coast dazzles with its mysterious grottos, craggy cliffs and shimmering bays. Grab a seat on the sea side of a regional bus to soak up views on the fabled route from artsy Positano to Amalfi. Ravello offers some respite from the crowds, plus the stunning Villa Cimbrone, which overlooks the Bay of Salerno. The historic section of Sorrento has winding streets filled with craftspeople. Capri is only a hydrofoil or ferry ride away.

A small city with big appeal, Bialystok is a charming Polish town. Visit the impressive Branickis' Palace or admire the beautiful 19th-century architecture of Warszawska Street or follow the historic Jewish Heritage Trail. Performances at the Białystok Puppet Theater are fun for the whole family, as is the dining experience at a local milk bar.

The museums of Lisbon celebrate the rich history and culture of this Portuguese capital city. The Maritime Museum is perfect for kids (and grown-ups!) who adore all things nautical, while the Casa-Museu Dr. Anastácio Gonçalves is a hidden gem of colorful artwork. To fully appreciate the city’s dramatic stone architecture you can take a guided walking tour, or customize your own tour, making sure to visit the Padrao dos Descobrimentos, the Mosteiro dos Jeronimos, and the UNESCO World Heritage site the Torre de Belem.

Golden palaces, floating markets, majestic porcelain-laid spires…you've never seen a capital city quite like Bangkok. Visit Pratunam or Siam Square for premium shopping, then unwind in the European-style gardens of Dusit. Thon Buri is home to the awesome Wat Arun temple, and over in Phra Nakhon, you’ll find the Wat Pho temple of the Reclining Buddha. Savor mango sticky rice at a food stall before taking in the gilded splendor of the Grand Palace.

The Singapore cityscape looks like it was ripped from the pages of a science fiction comic book. If you’re hungry for a true Singapore experience, sample the myriad street foods or take a cultural cooking class. The Botanic Gardens and the Gardens By the Bay offer a slice of horticultural heaven, and the observation deck of the Sands SkyPark makes you feel like you’re high above the clouds. The banks and walkways along the Singapore River bustle with local activity.

The charming Vietnamese capital has aged well, preserving the Old Quarter, monuments and colonial architecture, while making room for modern developments alongside. Hanoi may have shrugged off several former names, including Thang Long, or "ascending dragon," but it hasn't forgotten its past, as sites such as Ho Chi Minh's Mausoleum and Hoa Lo Prison attest. Lakes, parks, shady boulevards and more than 600 temples and pagodas add to the appeal of this city, which is easily explored by taxi.
