The Banana Pancake Trail is the name given to growing routes around Southeast Asia travelled by backpackers and other tourists. The Trail has no clear geographical definition. […] It is a metaphor to describe the ever-developing travellers’ trails in South and Southeast Asia, rather than an actual route or road.

 
WORD OF THE DAY (Vietnamese): em ơi!
