Hiking (徒步旅行) is a good way to exercise. Most people choose to hike in the countryside, in the forests, or in the mountains. They like to be close to nature and exercise to be healthy at the same time.
Would you like to go on a hike next vacation? Before you start, there are some points you have to know: a hike can take a few hours or weeks. If you are a beginner, you should start with a hike that you can finish in one day. As you get stronger, you can go on overnight hikes. Later you can go on longer hikes, which may last for days or weeks.
For safety reasons, hikers should hike with others. You should have one or two friends with you. However, if you decide to be alone, you’d better let someone know where you are going and when you will return. It is also a good idea to carry a map. It is necessary to take a back-pack（背包）while hiking. You can carry food, clothing and other things on your back in a pack. Back-packers can stay many days in places where there is no food to buy.
