Often compared to Venice due to its abundance of canals, Alappuzha is the gateway to the backwaters of Kerala. Rent a houseboat for an up-close view of the palm-lined waterways. In August, the snake-boat race is a remarkable festival—each traditional boat has a crew of over 100 local sailors.

A blending of several small villages on the southwestern coast created the current incarnation of Kochi (or Cochin), where sunset strolls, sampling fresh fish from seaside vendors and boat rides through the islands just offshore top visitors' to-do lists. Art centers showcase the traditional dance, Kathakali. European influences are seen in the 16th-century Portuguese-built churches and forts, while the mark of early Chinese traders is visible in the unusual fishing nets dotting the shoreline.

Bali is a living postcard, an Indonesian paradise that feels like a fantasy. Soak up the sun on a stretch of fine white sand, or commune with the tropical creatures as you dive along coral ridges or the colorful wreck of a WWII war ship.

The “artistic capital” of Ubud is the perfect place to see a cultural dance performance, take a batik or silver-smithing workshop, or invigorate your mind and body in a yoga class.

If the mention of Mykonos doesn’t immediately bring to mind bright white buildings, turquoise skies and tanned bodies lining golden sandy beaches, you’ve been living under a rock. The most popular Greek Island in the Aegean Sea is all about energy and attracts a diverse and upscale crowd that thrives on its stylish nightlife. During the day some privacy can be had in the more secluded north beaches, but the south beaches are all party. Ski, jet-ski, windsurf, horseback ride, parasail or just save up your energy for the evening ahead, like most of your fellow travelers in Mykonos.

The biggest beach resort on the Adriatic Sea, Rimini is a favored Italian seaside holiday destination for Italians themselves. The city offers an impressive nine miles of beaches, though many of these have private access for the scores of hotels facing the shore.

Rimini also boasts many great restaurants and an energetic nightlife.

Galas, regattas, the Film Festival and an outrageously attractive and affluent set characterize Cannes. Vast yachts obscure the view and the town lives up to its motto, "Life is a festival." People-watching is the activity that brings most visitors to Cannes, and hotel-lined La Croisette provides a fine promenade. First popularized by Coco Chanel, Cannes beaches are a huge draw. Get expensive seaside food and drinks service on hotel sand or opt for the free public beaches, Plages du Midi and de la Boca.
