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.

Sprawling tea plantations surround the serene hills of Munnar, which attract adventure travelers hungry for paragliding, treks to Anaimudi (South India's highest peak) and hikes originating at the confluence of three mountain streams. The stone Christ Church, built by the British in 1910, is adorned with renowned works of stained glass, and Eravikulam National Park, about 10 miles away, is home to equally colorful wildlife, including the endangered Nilgiri Tahr (ibex), ruddy mongoose and 120 bird species.

Let the beautiful coastal town of Varkala melt your worries and tensions away. Varkala’s peaceful seaside cliffs adjoin the Arabian Sea, setting the scene for several water spouts and wellness spas. The waters lapping at Papanasam beach are considered to have holy, sin-cleansing properties, and the nearby Ayurveda treatment center will cleanse what the ocean missed.

Da Nang is laid-back and friendly, maybe because everyone you meet has just finished an amazing meal. Culinary tours are a hugely popular way to experience literal local flavor. After you’ve stuffed yourself with bold noodle soups and savory street foods, walk it off by exploring the limestone caves and Buddhist grottos of the Marble Mountains.

The caves of Plettenberg Bay are wrinkles in time, lined with ancient artifacts that date to the Middle Stone Age. Under the sun, Robberg, Central and Lookout beaches are pristine stretches of white sand, magnets for tourists, seagulls and dolphins, who bob playfully just off shore. Wildlife lovers will delight at the Birds of Eden aviary and Monkeyland. (How can you not have fun in a place called Monkeyland?)

Quaint alpine villages and great skiing entice travelers to the Grisons. The sparsely populated region of eastern Switzerland contains the source of the Rhine and Inn rivers, 140 square miles of glaciers and dense pine forests. Join the ski action at the resorts of St. Moritz, Davos and Arosa or stake a lofty claim with a visit to Juf, which boasts the highest altitude of any inhabited village in the Alps. In summer, take a hike through the Engadine Valley in the unspoiled beauty of Swiss National Park.
