City-states are rare in the present day—and none are quite like Singapore. In the 20th century, the Southeast Asian nation hurtled itself into the modern world, and it continues to expand its state-of-the-art transportation system and build its edgy skyline. Yet Singapore's urban plan wisely maintained its intimate neighborhoods, many with streets lined with colorful shophouses (a type of building unique to parts of Asia, with businesses located on their ground floors and residences above).

Koh Samui can feel like a screensaver landscape. As if designed by Mother Nature for posters, calendars and daydreams, it’s Thailand’s most famous island for a number of reasons. The beach-fringed coast is edged with vivid, blue water that’s a surf-and-sand playground for snorkeling, scuba diving, kayaking, building sandcastles and simply lounging. Along with busy food stalls and restaurants where you can find a whole world of cuisine made with local produce and fresh seafood as well as authentic Thai dishes, the lively streets are lined with bars, boutiques, markets and spas.

With dreamy landscapes and island adventures from boat excursions to nature treks, you'll soon be enchanted by Koh Samui.
