Backpacking has a long history dating back to the 18th century Grand Tour. It became more popular in the late 1960s after the National Scenic Trail Act. Typical backpackers are students and young adults in their late teens to early 30s traveling on a low budget. They stay in hostels and interact with local cultures. Backpacking brings economic benefits to remote regions but governments don't always recognize this. Increased travel costs and money exchange issues present threats.
