Nabq Bay is pristine and peaceful, thanks in large part to its status as a protected area. Here, mingle with dozens of species of flora and fauna amid the mangroves or dive into the sparkling water to explore the nearby coral reef. "Wild" (unguided) snorkeling is popular here—happy swimmers bob along as peacefully as the undisturbed wildlife. More adventurous travelers can venture into the desert on one of the many popular quad tours.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment.

As if a golden Greek beach could get any more special—wander to the northern point of Tsilivi to check out the remains of a Venetian observatory and observe the mashup of awe-inspiring history and contemporary vacationer culture.

Founded by the Berbers in the 2nd millennium BCE, the city of Tunis has been controlled by Phoenicians, Romans, Arab Muslims, the Ottomans, the Spanish, the French and the Germans, finally achieving independence as the capital of Tunisia in 1956. This history has made Tunis a mélange of ancient and modern cultures. The medina is a network of narrow alleyways, mosques, mausoleums, palaces and a souq where shoppers haggle over the price of everything from filigreed gold to inexpensive souvenirs.

This city, full of colorful homes, canals and bridges, is one of Europe's most picturesque capitals. Must-sees on any visitor's itinerary include the Anne Frank House, the Van Gogh Museum and the world's only floating flower market.

For an unusual and memorable alternative to hotels, consider staying in a houseboat.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same.

Golden palaces, floating markets, majestic porcelain-laid spires…you've never seen a capital city quite like Bangkok.

Savor mango sticky rice at a food stall before taking in the gilded splendor of the Grand Palace.

Langkawi is a serene archipelago of 140 islands – only a few of which are inhabited. The largest of these is the eponymous Langkawi Island, which has UNESCO World Geopark status because of its richly populated (by wildlife, that is) conservation areas. The best way to experience these ecological wonders is from high above, on the Langkawi Sky Bridge that stretches above the rainforest. Cheekily-named Pregnant Maiden freshwater lake is a great place to take a dip or play keep-away with the kleptomaniac monkeys.
