What to go on holiday, but don’t have enough money for luxury (豪华的) hotels and expensive trips? Backpacking might be right up your street.
Backpacking is a very cheap kind of travel. European and American students and young adults who may not have all that much money often do it. It is called backpacking because, instead of using a suitcase (手提箱), people put all their things in a large backpack. A backpack sits on your back, and you pack all your clothes inside.
The most popular places for backpacking are Southeast Asia and South America. These countries aren’t very expensive, and are also very hot for most of the year. India and Australia are also very popular. In 2002, over 400,000 backpackers hit Australia. Sometimes, backpacking can be dangerous. A British backpacker was recently shot dead at a beach party in Thailand, and every year similar things happen.
Backpacking, in fact, is much more than a holiday—for young people in Europe, it is seen as a way of learning about the world.
Backpackers often travel alone for many months, as this is seen as more of an adventure and challenge. Beyond finding new words, backpacking, people say, is all about “finding yourself”.
