The sun-drenched Canary Islands lie close to North Africa and have an exotic flavour of their own. Hundreds of volcanoes, rolling sand dunes, rich forests and rugged cliffs dapple these seven Atlantic gems. Catch a ferry to Lanzarote. Ride a camel through volcanic Timanfaya National Park. Take on Tenerife, home of Mount Teide, Spain's tallest peak. Romp Grand Canary's beaches or hike La Gomera's Garajonay National Park. More adventures await on tiny El Hierro, verdant La Palma and peaceful Fuerteventura.

Glamourous Santorini is deliciously different. Geographical newness is in part to thank. The island’s popular black volcanic Perissa and Kamari beaches are big draws, as is its arguably most famous Red Beach near Akrotiri (which is the place to go for archaeology buffs). Santorini curves round a giant lagoon in the Cyclades islands, offering stunning views from sky-high towns, eclectic cuisine, lovely galleries, thriving nightlife and excellent wines.

The nine islands that make up the Azores are in fact the peaks of some of the world's tallest mountains, reaching from deep beneath the Atlantic. The once-uninhabited, volcanic archipelago now hosts thousands of tourists every year who flock to the islands for sun, sand and verdant mountain scenery. From the beaches of Praia da Vitoria to the bustling marina of Horta, to the bubbling volcanic ground "ovens" of Furnas, these islands offer unparalleled--and unusual--adventures to discover.

Strung below craggy mountains, the Omani capital of Muscat is one of the Middle East’s oldest and most picturesque cities. Between its corniches and modern quarter are Portuguese-built forts, blue-domed mosques, royal palaces, and souks, all heavy with the sense of a lost Arabia.

We won't lie: Niagara Falls is uber-touristy. There are wax museums and a Ripley's Believe It or Not Museum, and if it's a fast-food chain, you can probably find it here. But even the most jaded hipster shouldn't pass up a chance to visit this town, because the Falls themselves are spectacular.

Situated amidst lush green, forested hills on the highest peak in the Aravali range, Mount Abu is the summer capital for the Indian state of Rajasthan. Its cool and soothing climate makes it an ideal retreat. Explore a number of Jain temples, including the Dilwara Temples, a complex carved of while marble, or visit the nearby Achalgarh fort, which houses many beautiful temples of its own.

East meets West in this sun-soaked state, where Indian culture intertwines with Portuguese influences left over from a 500-year occupation. The beaches have long served as a magnet for serene hedonists. To the north, the tourist-centric scene is prevalent, with an international flair that is now skewing more hip than hippie. Travel south for stretches of unspoiled sand and an escape from large resorts. Temples, mosques and wildlife sanctuaries provide diversions from the beach.
