Exploring south-southeast Asia.

I’m planning a spring-summer odyssey in Asia, from India by land to Nepal, Thailand, Laos, and perhaps, Vietnam, China, Malaysia, and/or Singapore. I live in North America, and have been vagabonding in Europe and Africa, but never to Asia. Advice? Must-sees? (You can message me, if you prefer.) I can’t wait to be among the beautiful lands, cultures, and peoples of Asia!
