Thailand is a country of many contrasting facets, with glorious beaches as well as forests, jungles and mountains. Whether you want to swim, sunbathe or explore the wildlife, a family holiday in Thailand will never be dull.If you're looking for seaside relaxation, visit the beaches and bay of Hat Karon in Phuket with sand dunes and palm trees. The island of Ko Tao has coral reefs and is the place to go if you want to learn to dive, but you can also go mountain biking or just sunbathe on the beach. The Royal Barge National Museum in Bangkok houses several barges built for Thailand's kings; the beautifully detailed carving is quite breathtaking. Doi Suthep-Doi Pui National Park in Chiang Mai has a wealth of flowering plants and ferns as well as three hundred species of birds. If you're in the mood for a quiet spot, try the town of Sangkhlaburi; from there you can set off on an elephant trek or jungle tour. For mountains and forests, visit the north-western province of Mai Hong Son.

With more than 7,000 islands consisting of rice paddies, volcanos, mega-metropolises, world-class surf spots, and endemic wildlife, the Philippines is one of the most dazzling and diverse countries in all of Asia. Not to mention, it’s home to some of the world’s best beaches, too.

The biggest island in the Philippines, Luzon is also one of the most diverse—it’s where mountain peaks and volcanoes meet miles of coastline, and indigenous culture melds with Spanish colonial history. You can relax at the beach in Pagudpud, hike with locals up the Batad Rice Terraces, ride in a horse-drawn carriage in Vigan, and snack on street food and dance the night away in Manila. You’ll need a few days and a bus pass, but you’ll be glad you stayed.

Set your own pace by cycling through Khmer ruins at Angkor Wat or pedaling the banks of the mighty Mekong. Trek off the beaten path on eco-adventures through the Cardamom Mountains, southern tropical islands or crater lakes of the remote northeast. Add urban adventure and hire a "motodop" taxi in Siem Reap.

You could spend months exploring Taiwan’s Buddhist temples, villages, cities, and mountains and still barely scratch the surface of all the island has to offer. Here Confucius meets C-pop in a cultural mash-up of a place where traditional festivals are as important as hip-hop and cell phones. Taipei, Taichung, and Kaohsiung each burst with opportunities to explore, learn, shop, and dine. Don’t miss breathtaking natural features like Sun Moon Lake, the hot springs of Tainan, and Taroko Gorge.

Malaysia is a beautifully complex vacation destination, a land where ancient rainforests give way to multicultural city life. Capital city Kuala Lumpur is visually defined by the iconic Petronas Twin Towers, while in charming Melaka the vibe is more quaint and historical. Many of the country’s national parks offer opportunities for fantastic whitewater rafting, and the exclusive Sipadan dive site (off the east coast of Borneo) is among the best in the world.
