10 days is too less a time - especially for these 4 countries, each of whom offers such a huge variety of experiences on their own. I would say pick up Indonesia and Vietnam in one trip, and Thailand and Myanmar in the other one.
Indonesia is a beautiful assault on your senses. It is a spectacle of beaches and volcanoes. It is rich diversity coupled with pulse raising adventure. It is the extraordinarily imaginative Sumatra and the enterprising Flores. It is the gradual hair-raising excitement when you go from watching the lounging orangutans to the prowling komodo. From the precision of the Balinese dancer to the idyllic white sands of the Sumbawa; the glamour of Jakarta to the dramatic history of the Banda Islands; mouthwatering Bali to the magnificent Borobudur, it is the sheer contrast that one encounters here that makes Indonesia a truly intriguing experience.
The reasons to love Vietnam are many, with it being a glorious assault on your sense, a culinary superpower, home to its own share of thrills and chills, and a great testament to the progress that can be made due to peace after war. You can choose to escape to the surrealistic limestone islands from Halong Bay, explore the world’s most spectacular cave systems or just hike around the place indulging in activities that are sure to get your adrenaline pumping.
From the illimitable lengths of food stalls filled to the brim with quirky, local delicacies at Hanoi coupled with a stroll along the Lake Huu Tiep to the culture centric treks of the Muong Hoa Valley, Vietnam is an adventure haven. Visit the famous mausoleum of a former Saigon governor, Le Van Duyet, at the even more popular Ho Chi Minh City and enjoy a tour ending with sunsets at Turtle Lake. Discover for yourself the traditional handicrafts of Hoi An or just merge into the placidity of the seemingly empyreal beaches of Phu Quoc. Snorkel off into the sunset only to return for a delicious treat of seafood unique to this country.
