Thailand’s largest island is an international magnet for beach lovers and serious divers, who enthusiastically submerge themselves in the Andaman Sea. Blue lagoons and salmon sunsets make for a dream-like atmosphere, and indeed, a vacation here can feel a bit surreal. Watersports are the most popular activities, though once you’ve had enough sun there’s still plenty to explore at the island’s aquariums, gardens, and Buddhist temples.

At nearly three miles long, Karon’s beach stretches on and on and on… so this might be the perfect spot for travelers who want as much space as possible around their beach blankets. TripAdvisor travelers say the diving is fabulous. And bring the kids-- Karon is known as a family-friendly town.

Packed with all the amenities—and unsightly development—of a modern Thai harbor town, Ao Nang is a popular base camp for exploring Krabi’s karst islands. A long arc of sand is shared by long-tailed boats delivering day-trippers to resorts and rowdy beach bars.

The southern Thailand town of Krabi serves as base camp for exploring the province of the same name, a lush region of jungles, limestone cliffs and idyllic isles floating just offshore in the Andaman Sea. Buddhist shrines still used by local monks are tucked into the chambers of the town's top attraction, Tiger Cave. The riverside pier links travelers with ferries and longboats to the best scuba diving, rock climbing and white sand beaches on the coast.

The dive sites surrounding Ko Lanta are considered to be some of Thailand’s finest. An intricate system of reefs, islets, and underwater caves are teeming with vibrant sea life. While you splash in the waves you may catch a glimpse of a Moken (sea gypsy) boat, gliding nomadically through the waters. Cap off your day with mouthwatering seafood, freshly caught and spicy enough to make your tongue tingle.

Can Tho is the main city of the Mekong Delta, the "nine dragon river delta" where the Mekong River empties into the South China Sea. It's also the main transportation center for the region. The extensive canals make for a pleasant boat ride, and the nearby floating markets offer authentic goods and exotic local fruit. *Fly into Ho Chi Minh City International Airport where you can take a car or van (approximately 4 hours) to Can Tho.

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. On shore, the lush jungle shelters stone temples and mischievous monkeys. 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.

A trip to Hiroshima is best kicked off with a visit to the Hiroshima Peace Memorial Park, which contains a museum, the remnants of buildings destroyed by the 1945 atomic bomb and monuments to the people killed by this nuclear attack. Understanding Hiroshima’s relatively recent devastation is key to fully appreciating its beauty and culture. Visit splendidly rebuilt historic sites like Hiroshima Castle and Shukkei-en Garden, and don’t miss the Itsukushima Shrine on the nearby island of Miyajima.

Tradition collides with pop culture in Tokyo, where you can reverently wander ancient temples before rocking out at a karaoke bar. Wake up before the sun to catch the lively fish auction at the Toyosu Market, then refresh with a walk beneath the cherry blossom trees that line the Sumida River. Spend some time in the beautiful East Gardens of the Imperial Palace, then brush up on your Japanese history at the Edo-Tokyo Museum. Don’t forget to eat as much sushi, udon noodles, and wagashi (Japanese sweets) as your belly can handle.

The delightful village of Watamu is an eco-tourist’s dream, lined with sandy white beaches and hotels dedicated to sustainable tourism. Watamu is a quick snorkel away from the Malindi Marine Reserve Park, and Turtle Beach is the ideal spot for a swim and a tanning session. The village proper features quaint Kenyan shopping stalls called dukas, where you can stock up with supplies. Make sure to visit the Gede Ruins, a mysterious and heavily overgrown 12th century Swahili village, and the beautifully fluttery Kipepeo Butterfly Project.

On the banks of the Volga River, Kazan sits austerely, its cityscape a visual confection of architecture that somehow manages to be both playful and severe. No matter your spiritual inclination, you simply must visit the Temple of All Religions, a Technicolor cultural center built by artist Ildar Khanov. Though still a work in progress, the "temple" is a feast for the eyes—and the spirit.
